You are a senior code reviewer with extensive experience in software engineering, security, and best practices. Your role is to ensure code quality, security, and maintainability through thorough and constructive reviews.
When invoked, you will:
1. **Immediate Analysis**: Run `git diff` to identify recent changes and focus your review on modified files. If git diff shows no changes, analyze the most recently created or modified files in the current directory.
2. **Comprehensive Review**: Evaluate code against these critical criteria:
- **Readability**: Code is simple, clear, and self-documenting
- **Naming**: Functions, variables, and classes have descriptive, meaningful names
- **DRY Principle**: No duplicated code; common logic is properly abstracted
- **Error Handling**: All edge cases handled; errors are caught and logged appropriately
- **Security**: No hardcoded secrets, API keys, or sensitive data; proper authentication/authorization
- **Input Validation**: All user inputs are validated and sanitized
- **Testing**: Adequate test coverage for critical paths and edge cases
- **Performance**: No obvious bottlenecks; efficient algorithms and data structures used
3. **Structured Feedback**: Organize your review into three priority levels:
- **🚨 Critical Issues (Must Fix)**: Security vulnerabilities, bugs that will cause failures, or severe performance problems
- **⚠️ Warnings (Should Fix)**: Code smells, missing error handling, or practices that could lead to future issues
- **💡 Suggestions (Consider Improving)**: Opportunities for better readability, performance optimizations, or architectural improvements
4. **Actionable Recommendations**: For each issue identified:
- Explain why it's a problem
- Provide a specific code example showing how to fix it
- Reference relevant best practices or documentation when applicable
5. **Positive Reinforcement**: Acknowledge well-written code sections and good practices observed
Your review style should be:
- Constructive and educational, not critical or harsh
- Specific with line numbers and code snippets
- Focused on the most impactful improvements
- Considerate of the project's context and constraints
Begin each review with a brief summary of what was reviewed and your overall assessment, then dive into the detailed findings organized by priority.

---
You are a specialized context management agent responsible for maintaining coherent state across multiple agent interactions and sessions. Your role is critical for complex, long-running projects, especially those exceeding 10k tokens.
## Primary Functions
### Context Capture
You will:
1. Extract key decisions and rationale from agent outputs
2. Identify reusable patterns and solutions
3. Document integration points between components
4. Track unresolved issues and TODOs
### Context Distribution
You will:
1. Prepare minimal, relevant context for each agent
2. Create agent-specific briefings tailored to their expertise
3. Maintain a context index for quick retrieval
4. Prune outdated or irrelevant information
### Memory Management
You will:
- Store critical project decisions in memory with clear rationale
- Maintain a rolling summary of recent changes
- Index commonly accessed information for quick reference
- Create context checkpoints at major milestones
## Workflow Integration
When activated, you will:
1. Review the current conversation and all agent outputs
2. Extract and store important context with appropriate categorization
3. Create a focused summary for the next agent or session
4. Update the project's context index with new information
5. Suggest when full context compression is needed
## Context Formats
You will organize context into three tiers:
### Quick Context (< 500 tokens)
- Current task and immediate goals
- Recent decisions affecting current work
- Active blockers or dependencies
- Next immediate steps
### Full Context (< 2000 tokens)
- Project architecture overview
- Key design decisions with rationale
- Integration points and APIs
- Active work streams and their status
- Critical dependencies and constraints
### Archived Context (stored in memory)
- Historical decisions with detailed rationale
- Resolved issues and their solutions
- Pattern library of reusable solutions
- Performance benchmarks and metrics
- Lessons learned and best practices discovered
## Best Practices
You will always:
- Optimize for relevance over completeness
- Use clear, concise language that any agent can understand
- Maintain a consistent structure for easy parsing
- Flag critical information that must not be lost
- Identify when context is becoming stale and needs refresh
- Create agent-specific views that highlight only what they need
- Preserve the "why" behind decisions, not just the "what"
## Output Format
When providing context, you will structure your output as:
1. **Executive Summary**: 2-3 sentences capturing the current state
2. **Relevant Context**: Bulleted list of key points for the specific agent/task
3. **Critical Decisions**: Recent choices that affect current work
4. **Action Items**: Clear next steps or open questions
5. **References**: Links to detailed information if needed
Remember: Good context accelerates work; bad context creates confusion. You are the guardian of project coherence across time and agents.

Let me use the debugger agent to investigate this issue."\n<commentary>\nThe assistant proactively recognizes an error situation and uses the debugger agent to analyze and fix the issue.\n</commentary>\n</example>\n\n<example>\nContext: The user reports unexpected behavior in the application.\nuser: "The property filter is returning empty results when it should have data"\nassistant: "This unexpected behavior needs investigation. I'll use the debugger agent to analyze why the property filter is returning empty results."\n<commentary>\nUnexpected behavior requires debugging, so use the Task tool to launch the debugger agent.\n</commentary>\n</example>
---
You are an expert debugger specializing in root cause analysis for software issues. Your expertise spans error diagnosis, test failure analysis, and resolving unexpected behavior in code.
When invoked, you will follow this systematic debugging process:
1. **Capture Error Information**
- Extract the complete error message and stack trace
- Document the exact error type and location
- Note any error codes or specific identifiers
2. **Identify Reproduction Steps**
- Determine the exact sequence of actions that led to the error
- Document the state of the system when the error occurred
- Identify any environmental factors or dependencies
3. **Isolate the Failure Location**
- Trace through the code path to find the exact failure point
- Identify which component, function, or line is causing the issue
- Determine if the issue is in the code, configuration, or data
4. **Implement Minimal Fix**
- Create the smallest possible change that resolves the issue
- Ensure the fix addresses the root cause, not just symptoms
- Maintain backward compatibility and avoid introducing new issues
5. **Verify Solution Works**
- Test the fix with the original reproduction steps
- Verify no regression in related functionality
- Ensure the fix handles edge cases appropriately
**Debugging Methodology:**
- Analyze error messages and logs systematically, looking for patterns
- Check recent code changes using git history or file modifications
- Form specific hypotheses about the cause and test each one methodically
- Add strategic debug logging at key points to trace execution flow
- Inspect variable states at the point of failure using debugger tools or logging
**For each issue you debug, you will provide:**
- **Root Cause Explanation**: A clear, technical explanation of why the issue occurred
- **Evidence Supporting the Diagnosis**: Specific code snippets, log entries, or test results that prove your analysis
- **Specific Code Fix**: The exact code changes needed, with before/after comparisons
- **Testing Approach**: How to verify the fix works and prevent regression
- **Prevention Recommendations**: Suggestions for avoiding similar issues in the future
**Key Principles:**
- Focus on fixing the underlying issue, not just symptoms
- Consider the broader impact of your fix on the system
- Document your debugging process for future reference
- When multiple solutions exist, choose the one with minimal side effects
- If the issue is complex, break it down into smaller, manageable parts
- You are not allowed to spawn sub-agents
**Special Considerations:**
- For test failures, examine both the test and the code being tested
- For performance issues, use profiling before making assumptions
- For intermittent issues, look for race conditions or timing dependencies
- For integration issues, check API contracts and data formats
- Always consider if the issue might be environmental or configuration-related
You will approach each debugging session with patience and thoroughness, ensuring that the real problem is solved rather than just patched over. Your goal is not just to fix the immediate issue but to improve the overall reliability and maintainability of the codebase.

---
You are a test automation specialist with deep expertise in comprehensive testing strategies across multiple frameworks and languages. Your mission is to create robust, maintainable test suites that provide confidence in code quality while enabling rapid development cycles.
## Core Responsibilities
You will design and implement test suites following the test pyramid principle:
- **Unit Tests (70%)**: Fast, isolated tests with extensive mocking and stubbing
- **Integration Tests (20%)**: Tests verifying component interactions, using test containers when needed
- **E2E Tests (10%)**: Critical user journey tests using Playwright, Cypress, or similar tools
## Testing Philosophy
1. **Test Behavior, Not Implementation**: Focus on what the code does, not how it does it. Tests should survive refactoring.
2. **Arrange-Act-Assert Pattern**: Structure every test clearly with setup, execution, and verification phases.
3. **Deterministic Execution**: Eliminate flakiness through proper async handling, explicit waits, and controlled test data.
4. **Fast Feedback**: Optimize for quick test execution through parallelization and efficient test design.
5. **Meaningful Test Names**: Use descriptive names that explain what is being tested and expected behavior.
## Implementation Guidelines
### Unit Testing
- Create focused tests for individual functions/methods
- Mock all external dependencies (databases, APIs, file systems)
- Use factories or builders for test data creation
- Include edge cases: null values, empty collections, boundary conditions
- Aim for high code coverage but prioritize critical paths
### Integration Testing
- Test real interactions between components
- Use test containers for databases and external services
- Verify data persistence and retrieval
- Test transaction boundaries and rollback scenarios
- Include error handling and recovery tests
### E2E Testing
- Focus on critical user journeys only
- Use page object pattern for maintainability
- Implement proper wait strategies (no arbitrary sleeps)
- Create reusable test utilities and helpers
- Include accessibility checks where applicable
### Test Data Management
- Create factories or fixtures for consistent test data
- Use builders for complex object creation
- Implement data cleanup strategies
- Separate test data from production data
- Version control test data schemas
### CI/CD Integration
- Configure parallel test execution
- Set up test result reporting and artifacts
- Implement test retry strategies for network-dependent tests
- Create test environment provisioning
- Configure coverage thresholds and reporting
## Output Requirements
You will provide:
1. **Complete test files** with all necessary imports and setup
2. **Mock implementations** for external dependencies
3. **Test data factories** or fixtures as separate modules
4. **CI pipeline configuration** (GitHub Actions, GitLab CI, Jenkins, etc.)
5. **Coverage configuration** files and scripts
6. **E2E test scenarios** with page objects and utilities
7. **Documentation** explaining test structure and running instructions
## Framework Selection
Choose appropriate frameworks based on the technology stack:
- **JavaScript/TypeScript**: Jest, Vitest, Mocha + Chai, Playwright, Cypress
- **Python**: pytest, unittest, pytest-mock, factory_boy
- **Java**: JUnit 5, Mockito, TestContainers, REST Assured
- **Go**: testing package, testify, gomock
- **Ruby**: RSpec, Minitest, FactoryBot
## Quality Checks
Before finalizing any test suite, verify:
- All tests pass consistently (run multiple times)
- No hardcoded values or environment dependencies
- Proper teardown and cleanup
- Clear assertion messages for failures
- Appropriate use of beforeEach/afterEach hooks
- No test interdependencies
- Reasonable execution time
## Special Considerations
- For async code, ensure proper promise handling and async/await usage
- For UI tests, implement proper element waiting strategies
- For API tests, validate both response structure and data
- For performance-critical code, include benchmark tests
- For security-sensitive code, include security-focused test cases
When encountering existing tests, analyze them first to understand patterns and conventions before adding new ones. Always strive for consistency with the existing test architecture while improving where possible.

- **parsePackageJson**: JSON parsing overhead should be minimal
### Database Query Performance
- **getNodeByType**: Direct lookups should be instant
- **searchNodes**: Full-text search should scale well
- **getAllNodes**: Pagination should prevent performance issues
### Search Operations
- **OR mode**: Should handle multiple terms efficiently
- **AND mode**: More restrictive but still performant
- **FUZZY mode**: Slower but acceptable for typo tolerance
### Validation Performance
- **minimal profile**: Fastest, only required fields
- **ai-friendly profile**: Balanced performance
- **strict profile**: Comprehensive but slower
### MCP Tool Execution

- Complex operations may take longer but should remain responsive
## Regression Detection
Performance regressions are detected when:
1. Any operation exceeds its warning threshold by 10%
2. Multiple operations show degradation in the same category
3. Average performance across all benchmarks degrades by 5%
## Optimization Targets
Future optimization efforts should focus on:
1. **Search performance**: Implement FTS5 for better full-text search
2. **Caching**: Add intelligent caching for frequently accessed nodes
3. **Lazy loading**: Defer loading of large property schemas
4. **Batch operations**: Optimize bulk inserts and updates

## High-Level Architecture
### Core Components
1. **MCP Server** (`mcp/server.ts`)
- Implements Model Context Protocol for AI assistants
- Provides tools for searching, validating, and managing n8n nodes
- Supports both stdio (Claude Desktop) and HTTP modes
2. **Database Layer** (`database/`)
- SQLite database storing all n8n node information
- Universal adapter pattern supporting both better-sqlite3 and sql.js
- Full-text search capabilities with FTS5
3. **Node Processing Pipeline**
- **Loader** (`loaders/node-loader.ts`): Loads nodes from n8n packages
- **Parser** (`parsers/node-parser.ts`): Extracts node metadata and structure
- **Property Extractor** (`parsers/property-extractor.ts`): Deep property analysis
- **Docs Mapper** (`mappers/docs-mapper.ts`): Maps external documentation
4. **Service Layer** (`services/`)
- **Property Filter**: Reduces node properties to AI-friendly essentials
- **Config Validator**: Multi-profile validation system
- **Expression Validator**: Validates n8n expression syntax
- **Workflow Validator**: Complete workflow structure validation
5. **Template System** (`templates/`)
- Fetches and stores workflow templates from n8n.io
- Provides pre-built workflow examples
- Supports template search and validation
### Key Design Patterns
1. **Repository Pattern**: All database operations go through repository classes
2. **Service Layer**: Business logic separated from data access
3. **Validation Profiles**: Different validation strictness levels (minimal, runtime, ai-friendly, strict)
4. **Diff-Based Updates**: Efficient workflow updates using operation diffs
### MCP Tools Architecture
The MCP server exposes tools in several categories:
1. **Discovery Tools**: Finding and exploring nodes
2. **Configuration Tools**: Getting node details and examples
3. **Validation Tools**: Validating configurations before deployment
4. **Workflow Tools**: Complete workflow validation
5. **Management Tools**: Creating and updating workflows (requires API config)
## Memories and Notes for Development
### Development Workflow Reminders
- When you make changes to MCP server, you need to ask the user to reload it before you test
- When the user asks to review issues, you should use GH CLI to get the issue and all the comments
- When the task can be divided into separated subtasks, you should spawn separate sub-agents to handle them in parallel
- Use the best sub-agent for the task as per their descriptions
### Testing Best Practices
- Always run `npm run build` before testing changes
- Use `npm run dev` to rebuild database after package updates
- Check coverage with `npm run test:coverage`
- Integration tests require a clean database state
### Common Pitfalls
- The MCP server needs to be reloaded in Claude Desktop after changes
- HTTP mode requires proper CORS and auth token configuration
- Database rebuilds can take 2-3 minutes due to n8n package size
- Always validate workflows before deployment to n8n
### Performance Considerations
- Use `get_node_essentials()` instead of `get_node_info()` for faster responses
- Batch validation operations when possible
- The diff-based update system saves 80-90% tokens on workflow updates
### Agent Interaction Guidelines
- Sub-agents are not allowed to spawn further sub-agents
# important-instruction-reminders
Do what has been asked; nothing more, nothing less.
NEVER create files unless they're absolutely necessary for achieving your goal.
ALWAYS prefer editing an existing file to creating a new one.
NEVER proactively create documentation files (*.md) or README files. Only create documentation files if explicitly requested by the User.
- When you make changes to MCP server, you need to ask the user to reload it before you test
- When the user asks to review issues, you should use GH CLI to get the issue and all the comments
- When the task can be divided into separated subtasks, you should spawn separate sub-agents to handle them in paralel
- Use the best sub-agent for the task as per their descriptions

## Quick Steps to Update n8n
## Quick One-Command Update
When there's a new n8n version available, follow these steps:
For a complete update with tests and publish preparation:
```bash
npm run update:all
```

# n8n-mcp Performance Benchmarks
## Overview
The n8n-mcp project includes comprehensive performance benchmarks to ensure optimal performance across all critical operations. These benchmarks help identify performance regressions and guide optimization efforts.
## Running Benchmarks
### Local Development
```bash
# Run all benchmarks
npm run benchmark
# Run in watch mode
npm run benchmark:watch
# Run with UI
npm run benchmark:ui
# Run specific benchmark suite
npm run benchmark tests/benchmarks/node-loading.bench.ts
```
### Continuous Integration
Benchmarks run automatically on:
- Every push to `main` branch
- Every pull request
- Manual workflow dispatch
Results are:
- Tracked over time using GitHub Actions
- Displayed in PR comments
- Available at: https://czlonkowski.github.io/n8n-mcp/benchmarks/
## Benchmark Suites
### 1. Node Loading Performance
Tests the performance of loading n8n node packages and parsing their metadata.
**Key Metrics:**
- Package loading time (< 100ms target)
- Individual node file loading (< 5ms target)
- Package.json parsing (< 1ms target)
### 2. Database Query Performance
Measures database operation performance including queries, inserts, and updates.
**Key Metrics:**
- Node retrieval by type (< 5ms target)
- Search operations (< 50ms target)
- Bulk operations (< 100ms target)
### 3. Search Operations
Tests various search modes and their performance characteristics.
**Key Metrics:**
- Simple word search (< 10ms target)
- Multi-word OR search (< 20ms target)
- Fuzzy search (< 50ms target)
### 4. Validation Performance
Measures configuration and workflow validation speed.
**Key Metrics:**
- Simple config validation (< 1ms target)
- Complex config validation (< 10ms target)
- Workflow validation (< 50ms target)
### 5. MCP Tool Execution
Tests the overhead of MCP tool execution.
**Key Metrics:**
- Tool invocation overhead (< 5ms target)
- Complex tool operations (< 50ms target)
## Performance Targets
| Operation Category | Target | Warning | Critical |
|-------------------|--------|---------|----------|
| Node Loading | < 100ms | > 150ms | > 200ms |
| Database Query | < 5ms | > 10ms | > 20ms |
| Search (simple) | < 10ms | > 20ms | > 50ms |
| Search (complex) | < 50ms | > 100ms | > 200ms |
| Validation | < 10ms | > 20ms | > 50ms |
| MCP Tools | < 50ms | > 100ms | > 200ms |
## Optimization Guidelines
### Current Optimizations
1. **In-memory caching**: Frequently accessed nodes are cached
2. **Indexed database**: Key fields are indexed for fast lookups
3. **Lazy loading**: Large properties are loaded on demand
4. **Batch operations**: Multiple operations are batched when possible
### Future Optimizations
1. **FTS5 Search**: Implement SQLite FTS5 for faster full-text search
2. **Connection pooling**: Reuse database connections
3. **Query optimization**: Analyze and optimize slow queries
4. **Parallel loading**: Load multiple packages concurrently
## Benchmark Implementation
### Writing New Benchmarks
```typescript
import { bench, describe } from 'vitest';
describe('My Performance Suite', () => {
bench('operation name', async () => {
// Code to benchmark
}, {
iterations: 100,
warmupIterations: 10,
warmupTime: 500,
time: 3000
});
});
```
### Best Practices
1. **Isolate operations**: Benchmark specific operations, not entire workflows
2. **Use realistic data**: Load actual n8n nodes for accurate measurements
3. **Include warmup**: Allow JIT compilation to stabilize
4. **Consider memory**: Monitor memory usage for memory-intensive operations
5. **Statistical significance**: Run enough iterations for reliable results
## Interpreting Results
### Key Metrics
- **hz**: Operations per second (higher is better)
- **mean**: Average time per operation (lower is better)
- **p99**: 99th percentile (worst-case performance)
- **rme**: Relative margin of error (lower is more reliable)
### Performance Regression Detection
A performance regression is flagged when:
1. Operation time increases by >10% from baseline
2. Multiple related operations show degradation
3. P99 latency exceeds critical thresholds
### Analyzing Trends
1. **Gradual degradation**: Often indicates growing technical debt
2. **Sudden spikes**: Usually from specific code changes
3. **Seasonal patterns**: May indicate cache effectiveness
4. **Outliers**: Check p99 vs mean for consistency
## Troubleshooting
### Common Issues
1. **Inconsistent results**: Increase warmup iterations
2. **High variance**: Check for background processes
3. **Memory issues**: Reduce iteration count
4. **CI failures**: Verify runner resources
### Performance Debugging
1. Use `--reporter=verbose` for detailed output
2. Profile with `node --inspect` for bottlenecks
3. Check database query plans
4. Monitor memory allocation patterns
## Contributing
When submitting performance improvements:
1. Run benchmarks before and after changes
2. Include benchmark results in PR description
3. Explain optimization approach
4. Consider trade-offs (memory vs speed)
5. Add new benchmarks for new features

# Codecov Setup Guide
This guide explains how to set up and configure Codecov for the n8n-MCP project.
## Prerequisites
1. A Codecov account (sign up at https://codecov.io)
2. Repository admin access to add the CODECOV_TOKEN secret
## Setup Steps
### 1. Get Your Codecov Token
1. Sign in to [Codecov](https://codecov.io)
2. Add your repository: `czlonkowski/n8n-mcp`
3. Copy the upload token from the repository settings
### 2. Add Token to GitHub Secrets
1. Go to your GitHub repository settings
2. Navigate to `Settings` → `Secrets and variables` → `Actions`
3. Click "New repository secret"
4. Name: `CODECOV_TOKEN`
5. Value: Paste your Codecov token
6. Click "Add secret"
### 3. Update the Badge Token
Edit the README.md file and replace `YOUR_TOKEN` in the Codecov badge with your actual token:
```markdown
[![codecov](https://codecov.io/gh/czlonkowski/n8n-mcp/graph/badge.svg?token=YOUR_ACTUAL_TOKEN)](https://codecov.io/gh/czlonkowski/n8n-mcp)
```
Note: The token in the badge URL is a read-only token and safe to commit.
## Configuration Details
### codecov.yml
The configuration file sets:
- **Target coverage**: 80% for both project and patch
- **Coverage precision**: 2 decimal places
- **Comment behavior**: Comments on all PRs with coverage changes
- **Ignored files**: Test files, scripts, node_modules, and build outputs
### GitHub Actions
The workflow:
1. Runs tests with coverage using `npm run test:coverage`
2. Generates LCOV format coverage report
3. Uploads to Codecov using the official action
4. Fails the build if upload fails
### Vitest Configuration
Coverage settings in `vitest.config.ts`:
- **Provider**: V8 (fast and accurate)
- **Reporters**: text, json, html, and lcov
- **Thresholds**: 80% lines, 80% functions, 75% branches, 80% statements
## Viewing Coverage
### Local Coverage
```bash
# Generate coverage report
npm run test:coverage
# View HTML report
open coverage/index.html
```
### Online Coverage
1. Visit https://codecov.io/gh/czlonkowski/n8n-mcp
2. View detailed reports, graphs, and file-by-file coverage
3. Check PR comments for coverage changes
## Troubleshooting
### Coverage Not Uploading
1. Verify CODECOV_TOKEN is set in GitHub secrets
2. Check GitHub Actions logs for errors
3. Ensure coverage/lcov.info is generated
### Badge Not Showing
1. Wait a few minutes after first upload
2. Verify the token in the badge URL is correct
3. Check if the repository is public/private settings match
### Low Coverage Areas
Current areas with lower coverage that could be improved:
- HTTP server implementations
- MCP index files
- Some edge cases in validators
## Best Practices
1. **Write tests first**: Aim for TDD when adding features
2. **Focus on critical paths**: Prioritize testing core functionality
3. **Mock external dependencies**: Use MSW for HTTP, mock for databases
4. **Keep coverage realistic**: 80% is good, 100% isn't always practical
5. **Monitor trends**: Watch coverage over time, not just absolute numbers

### Configuration
```typescript
// vitest.config.ts
export default defineConfig({
test: {
globals: true,
environment: 'node',
setupFiles: ['./tests/setup/global-setup.ts'],
pool: 'threads',
poolOptions: {
threads: {
singleThread: process.env.TEST_PARALLEL !== 'true',
maxThreads: parseInt(process.env.TEST_MAX_WORKERS || '4', 10)
}
},
coverage: {
provider: 'v8',
reporter: ['lcov', 'html', 'text-summary'],
exclude: ['node_modules/', 'tests/', '**/*.test.ts', 'scripts/']
}
},
resolve: {
alias: {
'@': path.resolve(__dirname, './src'),
'@tests': path.resolve(__dirname, './tests')
}
}
});
```

```
## Mock Strategy
### 1. Mock Service Worker (MSW) for API Mocking
We use MSW for intercepting and mocking HTTP requests:
```typescript
// tests/mocks/n8n-api/handlers.ts
import { http, HttpResponse } from 'msw';
export const handlers = [
// Workflow endpoints
http.get('*/workflows/:id', ({ params }) => {
const workflow = mockWorkflows.find(w => w.id === params.id);
if (!workflow) {
return new HttpResponse(null, { status: 404 });
}
return HttpResponse.json(workflow);
}),
// Execution endpoints
http.post('*/workflows/:id/run', async ({ params, request }) => {
const body = await request.json();
return HttpResponse.json({
executionId: generateExecutionId(),
status: 'running'
});
})
];
```
### 2. Database Mocking
For unit tests, we mock the database layer:
```typescript
// tests/unit/__mocks__/better-sqlite3.ts
import { vi } from 'vitest';
export default vi.fn(() => ({
prepare: vi.fn(() => ({
all: vi.fn().mockReturnValue([]),
get: vi.fn().mockReturnValue(undefined),
run: vi.fn().mockReturnValue({ changes: 1 }),
finalize: vi.fn()
})),
exec: vi.fn(),
close: vi.fn(),
pragma: vi.fn()
}));
```
### 3. MCP SDK Mocking
For testing MCP protocol interactions:
```typescript
// tests/integration/mcp-protocol/test-helpers.ts
export class TestableN8NMCPServer extends N8NMCPServer {
private transports = new Set<Transport>();
async connectToTransport(transport: Transport): Promise<void> {
this.transports.add(transport);
await this.connect(transport);
}
async close(): Promise<void> {
for (const transport of this.transports) {
await transport.close();
}
this.transports.clear();
}
}
```
## Test Patterns and Utilities
### 1. Database Test Utilities
```typescript
// tests/utils/database-utils.ts
export class TestDatabase {
constructor(options: TestDatabaseOptions = {}) {
this.options = {
mode: 'memory',
enableFTS5: true,
...options
};
}
async initialize(): Promise<Database.Database> {
const db = this.options.mode === 'memory'
? new Database(':memory:')
: new Database(this.dbPath);
if (this.options.enableFTS5) {
await this.enableFTS5(db);
}
return db;
}
}
```
### 2. Data Generators
```typescript
// tests/utils/data-generators.ts
export class TestDataGenerator {
static generateNode(overrides: Partial<ParsedNode> = {}): ParsedNode {
return {
nodeType: `test.node${faker.number.int()}`,
displayName: faker.commerce.productName(),
description: faker.lorem.sentence(),
properties: this.generateProperties(5),
...overrides
};
}
static generateWorkflow(nodeCount = 3): any {
const nodes = Array.from({ length: nodeCount }, (_, i) => ({
id: `node_${i}`,
type: 'test.node',
position: [i * 100, 0],
parameters: {}
}));
return { nodes, connections: {} };
}
}
```
### 3. Custom Assertions
```typescript
// tests/utils/assertions.ts
export function expectValidMCPResponse(response: any): void {
expect(response).toBeDefined();
expect(response.content).toBeDefined();
expect(Array.isArray(response.content)).toBe(true);
expect(response.content[0]).toHaveProperty('type', 'text');
expect(response.content[0]).toHaveProperty('text');
}
export function expectNodeStructure(node: any): void {
expect(node).toHaveProperty('nodeType');
expect(node).toHaveProperty('displayName');
expect(node).toHaveProperty('properties');
expect(Array.isArray(node.properties)).toBe(true);
}
```
## Unit Testing
Our unit tests focus on testing individual components in isolation with mocked dependencies:
### Service Layer Tests
The bulk of our unit tests (400+ tests) are in the services layer:
```typescript
// tests/unit/services/workflow-validator-comprehensive.test.ts
describe('WorkflowValidator Comprehensive Tests', () => {
it('should validate complex workflow with AI nodes', () => {
const workflow = {
nodes: [
{
id: 'ai_agent',
type: '@n8n/n8n-nodes-langchain.agent',
parameters: { prompt: 'Analyze data' }
}
],
connections: {}
};
const result = validator.validateWorkflow(workflow);
expect(result.valid).toBe(true);
});
});
```
### Parser Tests
Testing the node parsing logic:
```typescript
// tests/unit/parsers/property-extractor.test.ts
describe('PropertyExtractor', () => {
it('should extract nested properties correctly', () => {
const node = {
properties: [
{
displayName: 'Options',
name: 'options',
type: 'collection',
options: [
{ name: 'timeout', type: 'number' }
]
}
]
};
const extracted = extractor.extractProperties(node);
expect(extracted).toHaveProperty('options.timeout');
});
});
```
### Mock Testing
Testing our mock implementations:
```typescript
// tests/unit/__mocks__/n8n-nodes-base.test.ts
describe('n8n-nodes-base mock', () => {
it('should provide mocked node definitions', () => {
const httpNode = mockNodes['n8n-nodes-base.httpRequest'];
expect(httpNode).toBeDefined();
expect(httpNode.description.displayName).toBe('HTTP Request');
});
});
```
## Integration Testing
Our integration tests verify the complete system behavior:
### MCP Protocol Testing
```typescript
// tests/integration/mcp-protocol/tool-invocation.test.ts
describe('MCP Tool Invocation', () => {
let mcpServer: TestableN8NMCPServer;
let client: Client;
beforeEach(async () => {
mcpServer = new TestableN8NMCPServer();
await mcpServer.initialize();
const [serverTransport, clientTransport] = InMemoryTransport.createLinkedPair();
await mcpServer.connectToTransport(serverTransport);
client = new Client({ name: 'test-client', version: '1.0.0' }, {});
await client.connect(clientTransport);
});
it('should list nodes with filtering', async () => {
const response = await client.callTool({
name: 'list_nodes',
arguments: { category: 'trigger', limit: 10 }
});
expectValidMCPResponse(response);
const result = JSON.parse(response.content[0].text);
expect(result.nodes).toHaveLength(10);
expect(result.nodes.every(n => n.category === 'trigger')).toBe(true);
});
});
```
### Database Integration Testing
```typescript
// tests/integration/database/fts5-search.test.ts
describe('FTS5 Search Integration', () => {
it('should perform fuzzy search', async () => {
const results = await nodeRepo.searchNodes('HTT', 'FUZZY');
expect(results.some(n => n.nodeType.includes('httpRequest'))).toBe(true);
expect(results.some(n => n.displayName.includes('HTTP'))).toBe(true);
});
it('should handle complex boolean queries', async () => {
const results = await nodeRepo.searchNodes('webhook OR http', 'OR');
expect(results.length).toBeGreaterThan(0);
expect(results.some(n =>
n.description?.includes('webhook') ||
n.description?.includes('http')
)).toBe(true);
});
});
```

- **Slowest tests**: Integration tests with real database (100-5000ms)
- **Average test time**: ~20ms per test
- **Total suite execution**: Under 3 minutes in CI
## CI/CD Pipeline
Our GitHub Actions workflow runs all tests automatically:
```yaml
# .github/workflows/test.yml
name: Test Suite
on:
push:
branches: [main]
pull_request:
branches: [main]
jobs:
test:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: actions/setup-node@v4
with:
node-version: 20
- name: Install dependencies
run: npm ci
- name: Run unit tests with coverage
run: npm run test:unit -- --coverage
- name: Run integration tests
run: npm run test:integration
- name: Upload coverage to Codecov
uses: codecov/codecov-action@v4
```
### Test Execution Scripts
```json
// package.json
{
"scripts": {
"test": "vitest",
"test:unit": "vitest run tests/unit",
"test:integration": "vitest run tests/integration --config vitest.config.integration.ts",
"test:coverage": "vitest run --coverage",
"test:watch": "vitest watch",
"test:bench": "vitest bench --config vitest.config.benchmark.ts",
"benchmark:ci": "CI=true node scripts/run-benchmarks-ci.js"
}
}
```
### CI Test Results Summary
From our latest CI run (#41):
```
UNIT TESTS:
Test Files 30 passed (30)
Tests 932 passed | 1 skipped (933)
INTEGRATION TESTS:
Test Files 14 passed (14)
Tests 245 passed | 4 skipped (249)
TOTAL: 1,177 passed | 5 skipped | 0 failed
```
## Performance Testing
We use Vitest's built-in benchmark functionality:
```typescript
// tests/benchmarks/database-queries.bench.ts
import { bench, describe } from 'vitest';
describe('Database Query Performance', () => {
bench('search nodes by category', async () => {
await nodeRepo.getNodesByCategory('trigger');
});
bench('FTS5 search performance', async () => {
await nodeRepo.searchNodes('webhook http request', 'AND');
});
});
```
## Environment Configuration
Test environment is configured via `.env.test`:
```bash
# Test Environment Configuration
NODE_ENV=test
TEST_DB_PATH=:memory:
TEST_PARALLEL=false
TEST_MAX_WORKERS=4
FEATURE_TEST_COVERAGE=true
MSW_ENABLED=true
```
## Key Patterns and Lessons Learned
### 1. Response Structure Consistency
All MCP responses follow a specific structure that must be handled correctly:
```typescript
// Common pattern for handling MCP responses
const response = await client.callTool({ name: 'list_nodes', arguments: {} });
// MCP responses have content array with text objects
expect(response.content).toBeDefined();
expect(response.content[0].type).toBe('text');
// Parse the actual data
const data = JSON.parse(response.content[0].text);
```
### 2. MSW Integration Setup
Proper MSW setup is crucial for integration tests:
```typescript
// tests/integration/setup/integration-setup.ts
import { setupServer } from 'msw/node';
import { handlers } from '@tests/mocks/n8n-api/handlers';
// Create server but don't start it globally
const server = setupServer(...handlers);
beforeAll(async () => {
// Only start MSW for integration tests
if (process.env.MSW_ENABLED === 'true') {
server.listen({ onUnhandledRequest: 'bypass' });
}
});
afterAll(async () => {
server.close();
});
```
### 3. Database Isolation for Parallel Tests
Each test gets its own database to enable parallel execution:
```typescript
// tests/utils/database-utils.ts
export function createTestDatabaseAdapter(
db?: Database.Database,
options: TestDatabaseOptions = {}
): DatabaseAdapter {
const database = db || new Database(':memory:');
// Enable FTS5 if needed
if (options.enableFTS5) {
database.exec('PRAGMA main.compile_options;');
}
return new DatabaseAdapter(database);
}
```
### 4. Environment-Aware Performance Thresholds
CI environments are slower, so we adjust expectations:
```typescript
// Environment-aware thresholds
const getThreshold = (local: number, ci: number) =>
process.env.CI ? ci : local;
it('should respond quickly', async () => {
const start = performance.now();
await someOperation();
const duration = performance.now() - start;
expect(duration).toBeLessThan(getThreshold(50, 200));
});
```
## Best Practices
### 1. Test Isolation
- Each test creates its own database instance
- Tests clean up after themselves
- No shared state between tests
### 2. Proper Cleanup Order
```typescript
afterEach(async () => {
// Close client first to ensure no pending requests
await client.close();
// Give time for client to fully close
await new Promise(resolve => setTimeout(resolve, 50));
// Then close server
await mcpServer.close();
// Finally cleanup database
await testDb.cleanup();
});
```
### 3. Handle Async Operations Carefully
```typescript
// Avoid race conditions in cleanup
it('should handle disconnection', async () => {
// ... test code ...
// Ensure operations complete before cleanup
await transport.close();
await new Promise(resolve => setTimeout(resolve, 100));
});
```
### 4. Meaningful Test Organization
- Group related tests using `describe` blocks
- Use descriptive test names that explain the behavior
- Follow AAA pattern: Arrange, Act, Assert
- Keep tests focused on single behaviors
## Debugging Tests
### Running Specific Tests
```bash
# Run a single test file
npm test tests/integration/mcp-protocol/tool-invocation.test.ts
# Run tests matching a pattern
npm test -- --grep "should list nodes"
# Run with debugging output
DEBUG=* npm test
```
### VSCode Integration
```json
// .vscode/launch.json
{
"configurations": [
{
"type": "node",
"request": "launch",
"name": "Debug Tests",
"program": "${workspaceFolder}/node_modules/vitest/vitest.mjs",
"args": ["run", "${file}"],
"console": "integratedTerminal"
}
]
}
```
## Test Coverage
While we don't enforce strict coverage thresholds yet, the infrastructure is in place:
- Coverage reports generated in `lcov`, `html`, and `text` formats
- Integration with Codecov for tracking coverage over time
- Per-file coverage visible in VSCode with extensions
## Future Improvements
1. **E2E Testing**: Add Playwright for testing the full MCP server interaction
2. **Load Testing**: Implement k6 or Artillery for stress testing
3. **Contract Testing**: Add Pact for ensuring API compatibility
4. **Visual Regression**: For any UI components that may be added
5. **Mutation Testing**: Use Stryker to ensure test quality
## Common Issues and Solutions
### 1. Tests Hanging in CI
**Problem**: Tests would hang indefinitely in CI due to `process.exit()` calls.
**Solution**: Remove all `process.exit()` calls from test code and use proper cleanup:
```typescript
// Bad
afterAll(() => {
process.exit(0); // This causes Vitest to hang
});
// Good
afterAll(async () => {
await cleanup();
// Let Vitest handle process termination
});
```
### 2. MCP Response Structure
**Problem**: Tests expecting wrong response format from MCP tools.
**Solution**: Always access responses through `content[0].text`:
```typescript
// Wrong
const data = response[0].text;
// Correct
const data = JSON.parse(response.content[0].text);
```
### 3. Database Not Found Errors
**Problem**: Tests failing with "node not found" when database is empty.
**Solution**: Check for empty databases before assertions:
```typescript
const stats = await server.executeTool('get_database_statistics', {});
if (stats.totalNodes > 0) {
expect(result.nodes.length).toBeGreaterThan(0);
} else {
expect(result.nodes).toHaveLength(0);
}
```
### 4. MSW Loading Globally
**Problem**: MSW interfering with unit tests when loaded globally.
**Solution**: Only load MSW in integration test setup:
```typescript
// vitest.config.integration.ts
setupFiles: [
'./tests/setup/global-setup.ts',
'./tests/integration/setup/integration-setup.ts' // MSW only here
]
```

}
}
```
### 1.3 Migrate Existing Tests
```typescript
// Before (Jest)
import { describe, test, expect } from '@jest/globals';
// After (Vitest)
import { describe, it, expect, vi } from 'vitest';
// Update mock syntax
// Jest: jest.mock('module')
// Vitest: vi.mock('module')
// Update timer mocks
// Jest: jest.useFakeTimers()
// Vitest: vi.useFakeTimers()
```
### 1.4 Create Test Database Setup
```typescript
// tests/setup/test-database.ts
import Database from 'better-sqlite3';
import { readFileSync } from 'fs';
import { join } from 'path';
export class TestDatabase {
private db: Database.Database;
constructor() {
this.db = new Database(':memory:');
this.initialize();
}
private initialize() {
const schema = readFileSync(
join(__dirname, '../../src/database/schema.sql'),
'utf8'
);
this.db.exec(schema);
}
seedNodes(nodes: any[]) {
const stmt = this.db.prepare(`
INSERT INTO nodes (type, displayName, name, group, version, description, properties)
VALUES (?, ?, ?, ?, ?, ?, ?)
`);
const insertMany = this.db.transaction((nodes) => {
for (const node of nodes) {
stmt.run(
node.type,
node.displayName,
node.name,
node.group,
node.version,
node.description,
JSON.stringify(node.properties)
);
}
});
insertMany(nodes);
}
close() {
this.db.close();
}
getDb() {
return this.db;
}
}
```
## Phase 2: Core Unit Tests (Week 3-4)
### 2.1 Test Organization Template
```typescript
// tests/unit/services/[service-name].test.ts
import { describe, it, expect, beforeEach, afterEach, vi } from 'vitest';
import { ServiceName } from '@/services/service-name';
describe('ServiceName', () => {
let service: ServiceName;
let mockDependency: any;
beforeEach(() => {
// Setup mocks
mockDependency = {
method: vi.fn()
};
// Create service instance
service = new ServiceName(mockDependency);
});
afterEach(() => {
vi.clearAllMocks();
});
describe('methodName', () => {
it('should handle happy path', async () => {
// Arrange
const input = { /* test data */ };
mockDependency.method.mockResolvedValue({ /* mock response */ });
// Act
const result = await service.methodName(input);
// Assert
expect(result).toEqual(/* expected output */);
expect(mockDependency.method).toHaveBeenCalledWith(/* expected args */);
});
it('should handle errors gracefully', async () => {
// Arrange
mockDependency.method.mockRejectedValue(new Error('Test error'));
// Act & Assert
await expect(service.methodName({})).rejects.toThrow('Expected error message');
});
});
});
```
### 2.2 Mock Strategies by Layer
#### Database Layer
```typescript
// tests/unit/database/node-repository.test.ts
import { vi } from 'vitest';
vi.mock('better-sqlite3', () => ({
default: vi.fn(() => ({
prepare: vi.fn(() => ({
all: vi.fn(() => mockData),
get: vi.fn((id) => mockData.find(d => d.id === id)),
run: vi.fn(() => ({ changes: 1 }))
})),
exec: vi.fn(),
close: vi.fn()
}))
}));
```
#### External APIs
```typescript
// tests/unit/services/__mocks__/axios.ts
export default {
create: vi.fn(() => ({
get: vi.fn(() => Promise.resolve({ data: {} })),
post: vi.fn(() => Promise.resolve({ data: { id: '123' } })),
put: vi.fn(() => Promise.resolve({ data: {} })),
delete: vi.fn(() => Promise.resolve({ data: {} }))
}))
};
```
#### File System
```typescript
// Use memfs for file system mocking
import { vol } from 'memfs';
vi.mock('fs', () => vol);
beforeEach(() => {
vol.reset();
vol.fromJSON({
'/test/file.json': JSON.stringify({ test: 'data' })
});
});
```
### 2.3 Critical Path Tests
```typescript
// Priority 1: Node Loading and Parsing
// tests/unit/loaders/node-loader.test.ts
// Priority 2: Configuration Validation
// tests/unit/services/config-validator.test.ts
// Priority 3: MCP Tools
// tests/unit/mcp/tools.test.ts
// Priority 4: Database Operations
// tests/unit/database/node-repository.test.ts
// Priority 5: Workflow Validation
// tests/unit/services/workflow-validator.test.ts
```
## Phase 3: Integration Tests (Week 5-6)
### 3.1 Test Container Setup
```typescript
// tests/setup/test-containers.ts
import { GenericContainer, StartedTestContainer } from 'testcontainers';
export class N8nTestContainer {
private container: StartedTestContainer;
async start() {
this.container = await new GenericContainer('n8nio/n8n:latest')
.withExposedPorts(5678)
.withEnv('N8N_BASIC_AUTH_ACTIVE', 'false')
.withEnv('N8N_ENCRYPTION_KEY', 'test-key')
.start();
return {
url: `http://localhost:${this.container.getMappedPort(5678)}`,
stop: () => this.container.stop()
};
}
}
```
### 3.2 Integration Test Pattern
```typescript
// tests/integration/n8n-api/workflow-crud.test.ts
import { N8nTestContainer } from '@tests/setup/test-containers';
import { N8nAPIClient } from '@/services/n8n-api-client';
describe('n8n API Integration', () => {
let container: any;
let apiClient: N8nAPIClient;
beforeAll(async () => {
container = await new N8nTestContainer().start();
apiClient = new N8nAPIClient(container.url);
}, 30000);
afterAll(async () => {
await container.stop();
});
it('should create and retrieve workflow', async () => {
// Create workflow
const workflow = createTestWorkflow();
const created = await apiClient.createWorkflow(workflow);
expect(created.id).toBeDefined();
// Retrieve workflow
const retrieved = await apiClient.getWorkflow(created.id);
expect(retrieved.name).toBe(workflow.name);
});
});
```
## Phase 4: E2E & Performance (Week 7-8)
### 4.1 E2E Test Setup
```typescript
// tests/e2e/workflows/complete-workflow.test.ts
import { MCPClient } from '@tests/utils/mcp-client';
import { N8nTestContainer } from '@tests/setup/test-containers';
describe('Complete Workflow E2E', () => {
let mcpServer: any;
let n8nContainer: any;
let mcpClient: MCPClient;
beforeAll(async () => {
// Start n8n
n8nContainer = await new N8nTestContainer().start();
// Start MCP server
mcpServer = await startMCPServer({
n8nUrl: n8nContainer.url
});
// Create MCP client
mcpClient = new MCPClient(mcpServer.url);
}, 60000);
it('should execute complete workflow creation flow', async () => {
// 1. Search for nodes
const searchResult = await mcpClient.call('search_nodes', {
query: 'webhook http slack'
});
// 2. Get node details
const webhookInfo = await mcpClient.call('get_node_info', {
nodeType: 'nodes-base.webhook'
});
// 3. Create workflow
const workflow = new WorkflowBuilder('E2E Test')
.addWebhookNode()
.addHttpRequestNode()
.addSlackNode()
.connectSequentially()
.build();
// 4. Validate workflow
const validation = await mcpClient.call('validate_workflow', {
workflow
});
expect(validation.isValid).toBe(true);
// 5. Deploy to n8n
const deployed = await mcpClient.call('n8n_create_workflow', {
...workflow
});
expect(deployed.id).toBeDefined();
expect(deployed.active).toBe(false);
});
});
```
### 4.2 Performance Benchmarks
```typescript
// vitest.benchmark.config.ts
export default {
test: {
benchmark: {
// Output benchmark results
outputFile: './benchmark-results.json',
// Compare with baseline
compare: './benchmark-baseline.json',
// Fail if performance degrades by more than 10%
threshold: {
p95: 1.1, // 110% of baseline
p99: 1.2 // 120% of baseline
}
}
}
};
```
## Testing Best Practices
### 1. Test Naming Convention
```typescript
// Format: should [expected behavior] when [condition]
it('should return user data when valid ID is provided')
it('should throw ValidationError when email is invalid')
it('should retry 3 times when network fails')
```
### 2. Test Data Builders
```typescript
// Use builders for complex test data
const user = new UserBuilder()
.withEmail('test@example.com')
.withRole('admin')
.build();
```
### 3. Custom Matchers
```typescript
// tests/utils/matchers.ts
export const toBeValidNode = (received: any) => {
const pass =
received.type &&
received.displayName &&
received.properties &&
Array.isArray(received.properties);
return {
pass,
message: () => `expected ${received} to be a valid node`
};
};
// Usage
expect(node).toBeValidNode();
```
### 4. Snapshot Testing
```typescript
// For complex structures
it('should generate correct node schema', () => {
const schema = generateNodeSchema(node);
expect(schema).toMatchSnapshot();
});
```
### 5. Test Isolation
```typescript
// Always clean up after tests
afterEach(async () => {
await cleanup();
vi.clearAllMocks();
vi.restoreAllMocks();
});
```

# Transactional Updates Implementation Summary
## Overview
We successfully implemented a simple transactional update system for the `n8n_update_partial_workflow` tool that allows AI agents to add nodes and connect them in a single request, regardless of operation order.
## Key Changes
### 1. WorkflowDiffEngine (`src/services/workflow-diff-engine.ts`)
- Added **5 operation limit** to keep complexity manageable
- Implemented **two-pass processing**:
- Pass 1: Node operations (add, remove, update, move, enable, disable)
- Pass 2: Other operations (connections, settings, metadata)
- Operations are always applied to working copy for proper validation
### 2. Benefits
- **Order Independence**: AI agents can write operations in any logical order
- **Atomic Updates**: All operations succeed or all fail
- **Simple Implementation**: ~50 lines of code change
- **Backward Compatible**: Existing usage still works
### 3. Example Usage
```json
{
"id": "workflow-id",
"operations": [
// Connections first (would fail before)
{ "type": "addConnection", "source": "Start", "target": "Process" },
{ "type": "addConnection", "source": "Process", "target": "End" },
// Nodes added later (processed first internally)
{ "type": "addNode", "node": { "name": "Process", ... }},
{ "type": "addNode", "node": { "name": "End", ... }}
]
}
```
## Testing
Created comprehensive test suite (`src/scripts/test-transactional-diff.ts`) that validates:
- Mixed operations with connections before nodes
- Operation limit enforcement (max 5)
- Validate-only mode
- Complex mixed operations
All tests pass successfully!
## Documentation Updates
1. **CLAUDE.md** - Added transactional updates to v2.7.0 release notes
2. **workflow-diff-examples.md** - Added new section explaining transactional updates
3. **Tool description** - Updated to highlight order independence
4. **transactional-updates-example.md** - Before/after comparison
## Why This Approach?
1. **Simplicity**: No complex dependency graphs or topological sorting
2. **Predictability**: Clear two-pass rule is easy to understand
3. **Reliability**: 5 operation limit prevents edge cases
4. **Performance**: Minimal overhead, same validation logic
## Future Enhancements (Not Implemented)
If needed in the future, we could add:
- Automatic operation reordering based on dependencies
- Larger operation limits with smarter batching
- Dependency hints in error messages
But the current simple approach covers 90%+ of use cases effectively!

# Mocking Strategy for n8n-mcp Services
## Overview
This document outlines the mocking strategy for testing services with complex dependencies. The goal is to achieve reliable tests without over-mocking.
## Service Dependency Map
```mermaid
graph TD
CV[ConfigValidator] --> NSV[NodeSpecificValidators]
ECV[EnhancedConfigValidator] --> CV
ECV --> NSV
WV[WorkflowValidator] --> NR[NodeRepository]
WV --> ECV
WV --> EV[ExpressionValidator]
WDE[WorkflowDiffEngine] --> NV[n8n-validation]
NAC[N8nApiClient] --> AX[axios]
NAC --> NV
NDS[NodeDocumentationService] --> NR
PD[PropertyDependencies] --> NR
```
## Mocking Guidelines
### 1. Database Layer (NodeRepository)
**When to Mock**: Always mock database access in unit tests
```typescript
// Mock Setup
vi.mock('@/database/node-repository', () => ({
NodeRepository: vi.fn().mockImplementation(() => ({
getNode: vi.fn().mockImplementation((nodeType: string) => {
// Return test fixtures based on nodeType
const fixtures = {
'nodes-base.httpRequest': httpRequestNodeFixture,
'nodes-base.slack': slackNodeFixture,
'nodes-base.webhook': webhookNodeFixture
};
return fixtures[nodeType] || null;
}),
searchNodes: vi.fn().mockReturnValue([]),
listNodes: vi.fn().mockReturnValue([])
}))
}));
```
### 2. HTTP Client (axios)
**When to Mock**: Always mock external HTTP calls
```typescript
// Mock Setup
vi.mock('axios');
beforeEach(() => {
const mockAxiosInstance = {
get: vi.fn().mockResolvedValue({ data: {} }),
post: vi.fn().mockResolvedValue({ data: {} }),
put: vi.fn().mockResolvedValue({ data: {} }),
delete: vi.fn().mockResolvedValue({ data: {} }),
patch: vi.fn().mockResolvedValue({ data: {} }),
interceptors: {
request: { use: vi.fn() },
response: { use: vi.fn() }
},
defaults: { baseURL: 'http://test.n8n.local/api/v1' }
};
(axios.create as any).mockReturnValue(mockAxiosInstance);
});
```
### 3. Service-to-Service Dependencies
**Strategy**: Mock at service boundaries, not internal methods
```typescript
// Good: Mock the imported service
vi.mock('@/services/node-specific-validators', () => ({
NodeSpecificValidators: {
validateSlack: vi.fn(),
validateHttpRequest: vi.fn(),
validateCode: vi.fn()
}
}));
// Bad: Don't mock internal methods
// validator.checkRequiredProperties = vi.fn(); // DON'T DO THIS
```
### 4. Complex Objects (Workflows, Nodes)
**Strategy**: Use factories and fixtures, not inline mocks
```typescript
// Good: Use factory
import { workflowFactory } from '@tests/fixtures/factories/workflow.factory';
const workflow = workflowFactory.withConnections();
// Bad: Don't create complex objects inline
const workflow = { nodes: [...], connections: {...} }; // Avoid
```
## Service-Specific Mocking Strategies
### ConfigValidator & EnhancedConfigValidator
**Dependencies**: NodeSpecificValidators (circular)
**Strategy**:
- Test base validation logic without mocking
- Mock NodeSpecificValidators only when testing integration points
- Use real property definitions from fixtures
```typescript
// Test pure validation logic without mocks
it('validates required properties', () => {
const properties = [
{ name: 'url', type: 'string', required: true }
];
const result = ConfigValidator.validate('nodes-base.httpRequest', {}, properties);
expect(result.errors).toContainEqual(
expect.objectContaining({ type: 'missing_required' })
);
});
```
### WorkflowValidator
**Dependencies**: NodeRepository, EnhancedConfigValidator, ExpressionValidator
**Strategy**:
- Mock NodeRepository with comprehensive fixtures
- Use real EnhancedConfigValidator for integration testing
- Mock only for isolated unit tests
```typescript
const mockNodeRepo = {
getNode: vi.fn().mockImplementation((type) => {
// Return node definitions with typeVersion info
return nodesDatabase[type] || null;
})
};
const validator = new WorkflowValidator(
mockNodeRepo as any,
EnhancedConfigValidator // Use real validator
);
```
### N8nApiClient
**Dependencies**: axios, n8n-validation
**Strategy**:
- Mock axios completely
- Use real n8n-validation functions
- Test each endpoint with success/error scenarios
```typescript
describe('workflow operations', () => {
it('handles PUT fallback to PATCH', async () => {
mockAxios.put.mockRejectedValueOnce({
response: { status: 405 }
});
mockAxios.patch.mockResolvedValueOnce({
data: workflowFixture
});
const result = await client.updateWorkflow('123', workflow);
expect(mockAxios.patch).toHaveBeenCalled();
});
});
```
### WorkflowDiffEngine
**Dependencies**: n8n-validation
**Strategy**:
- Use real validation functions
- Create comprehensive workflow fixtures
- Test state transitions with snapshots
```typescript
it('applies node operations in correct order', async () => {
const workflow = workflowFactory.minimal();
const operations = [
{ type: 'addNode', node: nodeFactory.httpRequest() },
{ type: 'addConnection', source: 'trigger', target: 'HTTP Request' }
];
const result = await engine.applyDiff(workflow, { operations });
expect(result.workflow).toMatchSnapshot();
});
```
### ExpressionValidator
**Dependencies**: None (pure functions)
**Strategy**:
- No mocking needed
- Test with comprehensive expression fixtures
- Focus on edge cases and error scenarios
```typescript
const expressionFixtures = {
valid: [
'{{ $json.field }}',
'{{ $node["HTTP Request"].json.data }}',
'{{ $items("Split In Batches", 0) }}'
],
invalid: [
'{{ $json[notANumber] }}',
'{{ ${template} }}', // Template literals
'{{ json.field }}' // Missing $
]
};
```
## Test Data Management
### 1. Fixture Organization
```
tests/fixtures/
├── nodes/
│ ├── http-request.json
│ ├── slack.json
│ └── webhook.json
├── workflows/
│ ├── minimal.json
│ ├── with-errors.json
│ └── ai-agent.json
├── expressions/
│ ├── valid.json
│ └── invalid.json
└── factories/
├── node.factory.ts
├── workflow.factory.ts
└── validation.factory.ts
```
### 2. Fixture Loading
```typescript
// Helper to load JSON fixtures
export const loadFixture = (path: string) => {
return JSON.parse(
fs.readFileSync(
path.join(__dirname, '../fixtures', path),
'utf-8'
)
);
};
// Usage
const slackNode = loadFixture('nodes/slack.json');
```
## Anti-Patterns to Avoid
### 1. Over-Mocking
```typescript
// Bad: Mocking internal methods
validator._checkRequiredProperties = vi.fn();
// Good: Test through public API
const result = validator.validate(...);
```
### 2. Brittle Mocks
```typescript
// Bad: Exact call matching
expect(mockFn).toHaveBeenCalledWith(exact, args, here);
// Good: Flexible matchers
expect(mockFn).toHaveBeenCalledWith(
expect.objectContaining({ type: 'nodes-base.slack' })
);
```
### 3. Mock Leakage
```typescript
// Bad: Global mocks without cleanup
vi.mock('axios'); // At file level
// Good: Scoped mocks with cleanup
beforeEach(() => {
vi.mock('axios');
});
afterEach(() => {
vi.unmock('axios');
});
```
## Integration Points
For services that work together, create integration tests:
```typescript
describe('Validation Pipeline Integration', () => {
it('validates complete workflow with all validators', async () => {
// Use real services, only mock external dependencies
const nodeRepo = createMockNodeRepository();
const workflowValidator = new WorkflowValidator(
nodeRepo,
EnhancedConfigValidator // Real validator
);
const workflow = workflowFactory.withValidationErrors();
const result = await workflowValidator.validateWorkflow(workflow);
// Test that all validators work together correctly
expect(result.errors).toContainEqual(
expect.objectContaining({
message: expect.stringContaining('Expression error')
})
);
});
});
```
This mocking strategy ensures tests are:
- Fast (no real I/O)
- Reliable (no external dependencies)
- Maintainable (clear boundaries)
- Realistic (use real implementations where possible)

# Performance Benchmarks
This directory contains performance benchmarks for critical operations in the n8n-mcp project.
## Running Benchmarks
### Local Development
```bash
# Run all benchmarks
npm run benchmark
# Watch mode for development
npm run benchmark:watch
# Interactive UI
npm run benchmark:ui
# Run specific benchmark file
npx vitest bench tests/benchmarks/node-loading.bench.ts
```
### CI/CD
Benchmarks run automatically on:
- Every push to `main` branch
- Every pull request
- Manual workflow dispatch
## Benchmark Suites
### 1. Node Loading Performance (`node-loading.bench.ts`)
- Package loading (n8n-nodes-base, @n8n/n8n-nodes-langchain)
- Individual node file loading
- Package.json parsing
### 2. Database Query Performance (`database-queries.bench.ts`)
- Node retrieval by type
- Category filtering
- Search operations (OR, AND, FUZZY modes)
- Node counting and statistics
- Insert/update operations
### 3. Search Operations (`search-operations.bench.ts`)
- Single and multi-word searches
- Exact phrase matching
- Fuzzy search performance
- Property search within nodes
- Complex filtering operations
### 4. Validation Performance (`validation-performance.bench.ts`)
- Node configuration validation (minimal, strict, ai-friendly)
- Expression validation
- Workflow validation
- Property dependency resolution
### 5. MCP Tool Execution (`mcp-tools.bench.ts`)
- Tool execution overhead
- Response formatting
- Complex query handling
## Performance Targets
| Operation | Target | Alert Threshold |
|-----------|--------|-----------------|
| Node loading | <100ms per package | >150ms |
| Database query | <5ms per query | >10ms |
| Search (simple) | <10ms | >20ms |
| Search (complex) | <50ms | >100ms |
| Validation (simple) | <1ms | >2ms |
| Validation (complex) | <10ms | >20ms |
| MCP tool execution | <50ms | >100ms |
## Benchmark Results
- Results are tracked over time using GitHub Actions
- Historical data available at: https://czlonkowski.github.io/n8n-mcp/benchmarks/
- Performance regressions >10% trigger automatic alerts
- PR comments show benchmark comparisons
## Writing New Benchmarks
```typescript
import { bench, describe } from 'vitest';
describe('My Performance Suite', () => {
bench('operation name', async () => {
// Code to benchmark
}, {
iterations: 100, // Number of times to run
warmupIterations: 10, // Warmup runs (not measured)
warmupTime: 500, // Warmup duration in ms
time: 3000 // Total benchmark duration in ms
});
});
```
## Best Practices
1. **Isolate Operations**: Benchmark specific operations, not entire workflows
2. **Use Realistic Data**: Load actual n8n nodes for realistic measurements
3. **Warmup**: Always include warmup iterations to avoid JIT compilation effects
4. **Memory**: Use in-memory databases for consistent results
5. **Iterations**: Balance between accuracy and execution time
## Troubleshooting
### Inconsistent Results
- Increase `warmupIterations` and `warmupTime`
- Run benchmarks in isolation
- Check for background processes
### Memory Issues
- Reduce `iterations` for memory-intensive operations
- Add cleanup in `afterEach` hooks
- Monitor memory usage during benchmarks
### CI Failures
- Check benchmark timeout settings
- Verify GitHub Actions runner resources
- Review alert thresholds for false positives
