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.

|
||||
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

|
||||
- 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.

|
||||
|
||||
**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
|
||||
|
||||
**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.

# n8n-MCP Testing Architecture
|
||||
|
||||
## Executive Summary
|
||||
|
||||
This document outlines a comprehensive testing strategy for the n8n-MCP project, designed to improve from the current 2.45% coverage to a target of 80%+ coverage while ensuring reliability, maintainability, and performance.
|
||||
|
||||
## Current State Analysis
|
||||
|
||||
### Problems Identified
|
||||
- **Low Coverage**: 2.45% overall coverage
|
||||
- **Failing Tests**: HTTP server authentication tests failing
|
||||
- **No CI/CD**: No automated testing pipeline
|
||||
- **Mixed Test Types**: Tests scattered without clear organization
|
||||
- **No Mocking Strategy**: Direct dependencies on SQLite, n8n packages
|
||||
- **No Performance Testing**: No benchmarks for critical operations
|
||||
|
||||
## Testing Framework Strategy
|
||||
|
||||
### Primary Framework: Vitest (Replacing Jest)
|
||||
|
||||
**Rationale for Vitest over Jest:**
|
||||
- **Speed**: 10-100x faster for large test suites
|
||||
- **Native ESM Support**: Better alignment with modern TypeScript
|
||||
- **Built-in Mocking**: Superior mocking capabilities
|
||||
- **Watch Mode**: Instant feedback during development
|
||||
- **Compatibility**: Jest-compatible API for easy migration
|
||||
- **Type Safety**: Better TypeScript integration
|
||||
|
||||
### Supporting Frameworks
|
||||
|
||||
```typescript
|
||||
// vitest.config.ts
|
||||
import { defineConfig } from 'vitest/config';
|
||||
import tsconfigPaths from 'vite-tsconfig-paths';
|
||||
|
||||
export default defineConfig({
|
||||
plugins: [tsconfigPaths()],
|
||||
test: {
|
||||
globals: true,
|
||||
environment: 'node',
|
||||
setupFiles: ['./tests/setup/global-setup.ts'],
|
||||
coverage: {
|
||||
provider: 'v8',
|
||||
reporter: ['text', 'json', 'html', 'lcov'],
|
||||
exclude: [
|
||||
'node_modules/**',
|
||||
'dist/**',
|
||||
'**/*.d.ts',
|
||||
'**/*.test.ts',
|
||||
'**/*.spec.ts',
|
||||
'tests/**',
|
||||
'scripts/**'
|
||||
],
|
||||
thresholds: {
|
||||
lines: 80,
|
||||
functions: 80,
|
||||
branches: 75,
|
||||
statements: 80
|
||||
}
|
||||
},
|
||||
pool: 'threads',
|
||||
poolOptions: {
|
||||
threads: {
|
||||
singleThread: true
|
||||
}
|
||||
},
|
||||
testTimeout: 30000,
|
||||
hookTimeout: 30000
|
||||
}
|
||||
});

|
||||
## Mock Strategy
|
||||
|
||||
### 1. Database Mocking
|
||||
|
||||
```typescript
|
||||
// tests/unit/database/__mocks__/better-sqlite3.ts
|
||||
import { vi } from 'vitest';
|
||||
|
||||
export class Database {
|
||||
private data = new Map<string, any[]>();
|
||||
|
||||
prepare = vi.fn((sql: string) => ({
|
||||
all: vi.fn(() => this.data.get('nodes') || []),
|
||||
get: vi.fn((params) => this.data.get('nodes')?.find(n => n.id === params.id)),
|
||||
run: vi.fn(),
|
||||
finalize: vi.fn()
|
||||
}));
|
||||
|
||||
exec = vi.fn();
|
||||
close = vi.fn();
|
||||
|
||||
// Test helper to set mock data
|
||||
setMockData(table: string, data: any[]) {
|
||||
this.data.set(table, data);
|
||||
}
|
||||
}
|
||||
|
||||
export default vi.fn(() => new Database());
|
||||
```
|
||||
|
||||
### 2. n8n Package Mocking
|
||||
|
||||
```typescript
|
||||
// tests/unit/loaders/__mocks__/n8n-nodes-base.ts
|
||||
import { vi } from 'vitest';
|
||||
import { readFileSync } from 'fs';
|
||||
import { join } from 'path';
|
||||
|
||||
// Load real node definitions for testing
|
||||
const mockNodes = JSON.parse(
|
||||
readFileSync(join(__dirname, '../../fixtures/nodes/mock-nodes.json'), 'utf8')
|
||||
);
|
||||
|
||||
export const loadClassInIsolation = vi.fn((filePath: string) => {
|
||||
const nodeName = filePath.split('/').pop()?.replace('.node.js', '');
|
||||
return mockNodes[nodeName] || { description: { properties: [] } };
|
||||
});
|
||||
|
||||
export const NodeHelpers = {
|
||||
getVersionedNodeTypeAll: vi.fn(() => [])
|
||||
};
|
||||
```
|
||||
|
||||
### 3. External API Mocking
|
||||
|
||||
```typescript
|
||||
// tests/utils/mocks/axios.ts
|
||||
import { vi } from 'vitest';
|
||||
import type { AxiosRequestConfig } from 'axios';
|
||||
|
||||
export const createAxiosMock = () => {
|
||||
const mock = {
|
||||
get: vi.fn(),
|
||||
post: vi.fn(),
|
||||
put: vi.fn(),
|
||||
delete: vi.fn(),
|
||||
create: vi.fn(() => mock)
|
||||
};
|
||||
|
||||
// Default responses
|
||||
mock.get.mockResolvedValue({ data: { success: true } });
|
||||
mock.post.mockResolvedValue({ data: { id: '123' } });
|
||||
|
||||
return mock;
|
||||
};
|
||||
```
|
||||
|
||||
## Test Data Management
|
||||
|
||||
### 1. Factory Pattern
|
||||
|
||||
```typescript
|
||||
// tests/fixtures/factories/node.factory.ts
|
||||
import { Factory } from 'fishery';
|
||||
import type { INodeType } from 'n8n-workflow';
|
||||
|
||||
export const nodeFactory = Factory.define<INodeType>(({ sequence }) => ({
|
||||
name: `TestNode${sequence}`,
|
||||
displayName: `Test Node ${sequence}`,
|
||||
group: ['test'],
|
||||
version: 1,
|
||||
description: 'Test node for unit tests',
|
||||
defaults: {
|
||||
name: `Test Node ${sequence}`,
|
||||
},
|
||||
inputs: ['main'],
|
||||
outputs: ['main'],
|
||||
properties: [
|
||||
{
|
||||
displayName: 'Test Property',
|
||||
name: 'testProp',
|
||||
type: 'string',
|
||||
default: '',
|
||||
}
|
||||
]
|
||||
}));
|
||||
|
||||
// Usage in tests:
|
||||
const httpNode = nodeFactory.build({
|
||||
name: 'HttpRequest',
|
||||
properties: [/* custom properties */]
|
||||
});
|
||||
```
|
||||
|
||||
### 2. Builder Pattern
|
||||
|
||||
```typescript
|
||||
// tests/utils/builders/workflow.builder.ts
|
||||
export class WorkflowBuilder {
|
||||
private workflow = {
|
||||
name: 'Test Workflow',
|
||||
nodes: [],
|
||||
connections: {},
|
||||
settings: {}
|
||||
};
|
||||
|
||||
withName(name: string) {
|
||||
this.workflow.name = name;
|
||||
return this;
|
||||
}
|
||||
|
||||
addNode(node: any) {
|
||||
this.workflow.nodes.push(node);
|
||||
return this;
|
||||
}
|
||||
|
||||
connect(from: string, to: string) {
|
||||
this.workflow.connections[from] = {
|
||||
main: [[{ node: to, type: 'main', index: 0 }]]
|
||||
};
|
||||
return this;
|
||||
}
|
||||
|
||||
build() {
|
||||
return this.workflow;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## CI/CD Pipeline (GitHub Actions)

|
||||
## Testing Phases and Priorities
|
||||
|
||||
### Phase 1: Foundation (Weeks 1-2)
|
||||
1. **Setup Vitest** and migrate existing tests
|
||||
2. **Create mock infrastructure** for SQLite and n8n packages
|
||||
3. **Setup CI/CD** pipeline with basic checks
|
||||
4. **Target: 20% coverage**
|
||||
|
||||
### Phase 2: Core Unit Tests (Weeks 3-4)
|
||||
1. **Test critical services**: validators, parsers, loaders
|
||||
2. **Database layer** with full mocking
|
||||
3. **MCP tools** unit tests
|
||||
4. **Target: 50% coverage**
|
||||
|
||||
### Phase 3: Integration Tests (Weeks 5-6)
|
||||
1. **MCP protocol** integration tests
|
||||
2. **n8n API** integration with test containers
|
||||
3. **Database operations** with real SQLite
|
||||
4. **Target: 70% coverage**
|
||||
|
||||
### Phase 4: E2E & Performance (Weeks 7-8)
|
||||
1. **Complete workflow** scenarios
|
||||
2. **Performance benchmarks** for critical paths
|
||||
3. **Error handling** scenarios
|
||||
4. **Target: 80%+ coverage**
|
||||
|
||||
## Performance Testing
|
||||
|
||||
```typescript
|
||||
// tests/performance/node-loading.bench.ts
|
||||
import { bench, describe } from 'vitest';
|
||||
import { NodeLoader } from '@/loaders/node-loader';
|
||||
|
||||
describe('Node Loading Performance', () => {
|
||||
bench('Load single node', async () => {
|
||||
const loader = new NodeLoader();
|
||||
await loader.loadNode('n8n-nodes-base.httpRequest');
|
||||
});
|
||||
|
||||
bench('Load all nodes', async () => {
|
||||
const loader = new NodeLoader();
|
||||
await loader.loadAllNodes();
|
||||
}, {
|
||||
iterations: 10,
|
||||
time: 5000 // 5 second time budget
|
||||
});
|
||||
|
||||
bench('Parse complex node', async () => {
|
||||
const parser = new NodeParser();
|
||||
await parser.parseNode(complexNodeFixture);
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
## Error Testing Strategy
|
||||
|
||||
```typescript
|
||||
// tests/unit/services/error-scenarios.test.ts
|
||||
describe('Error Handling', () => {
|
||||
it('should handle network failures gracefully', async () => {
|
||||
const api = new N8nAPIClient();
|
||||
mockAxios.get.mockRejectedValue(new Error('Network error'));
|
||||
|
||||
await expect(api.getWorkflow('123'))
|
||||
.rejects.toThrow('Failed to fetch workflow');
|
||||
|
||||
expect(logger.error).toHaveBeenCalledWith(
|
||||
'Network error while fetching workflow',
|
||||
expect.any(Error)
|
||||
);
|
||||
});
|
||||
|
||||
it('should handle malformed data', () => {
|
||||
const validator = new ConfigValidator();
|
||||
const malformed = { nodes: 'not-an-array' };
|
||||
|
||||
const result = validator.validate(malformed);
|
||||
|
||||
expect(result.isValid).toBe(false);
|
||||
expect(result.errors).toContain('nodes must be an array');
|
||||
});
|
||||
});
|
||||
```
|
||||
|
||||
## Coverage Enforcement
|
||||
|
||||
```json
|
||||
// package.json scripts
|
||||
{
|
||||
"scripts": {
|
||||
"test": "vitest",
|
||||
"test:unit": "vitest run tests/unit",
|
||||
"test:integration": "vitest run tests/integration",
|
||||
"test:e2e": "vitest run tests/e2e",
|
||||
"test:coverage": "vitest run --coverage",
|
||||
"test:coverage:check": "vitest run --coverage --coverage.thresholdAutoUpdate=false",
|
||||
"test:watch": "vitest watch",
|
||||
"bench": "vitest bench",
|
||||
"bench:compare": "vitest bench --compare"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Monitoring and Reporting
|
||||
|
||||
