1. **Node Type Prefix Validation Catastrophe**
|
||||
- 5,000+ validation errors from single root cause
|
||||
- `nodes-base.X` vs `n8n-nodes-base.X` confusion
|
||||
- **Solution**: Auto-normalize prefixes (2-4 hours effort)
|
||||
|
||||
2. **TypeError in Node Information Tools**
|
||||
- 10-18% failure rate in get_node_essentials/info

# Template Mining Analysis - Alternative to P0-R3
|
||||
|
||||
**Date**: 2025-10-02
|
||||
**Context**: Analyzing whether to fix `get_node_for_task` (28% failure rate) or replace it with template-based configuration extraction
|
||||
|
||||
## Executive Summary
|
||||
|
||||
**RECOMMENDATION**: Replace `get_node_for_task` with template-based configuration extraction. The template database contains 2,646 real-world workflows with rich node configurations that far exceed the 31 hardcoded task templates.
|
||||
|
||||
## Key Findings
|
||||
|
||||
### 1. Template Database Coverage
|
||||
|
||||
- **Total Templates**: 2,646 production workflows from n8n.io
|
||||
- **Unique Node Types**: 543 (covers 103% of our 525 core nodes)
|
||||
- **Metadata Coverage**: 100% (AI-generated structured metadata)
|
||||
|
||||
### 2. Node Type Coverage in Templates
|
||||
|
||||
Top node types by template usage:
|
||||
```
|
||||
3,820 templates: n8n-nodes-base.httpRequest (144% of total templates!)
|
||||
3,678 templates: n8n-nodes-base.set
|
||||
2,445 templates: n8n-nodes-base.code
|
||||
1,700 templates: n8n-nodes-base.googleSheets
|
||||
1,471 templates: @n8n/n8n-nodes-langchain.agent
|
||||
1,269 templates: @n8n/n8n-nodes-langchain.lmChatOpenAi
|
||||
792 templates: n8n-nodes-base.telegram
|
||||
702 templates: n8n-nodes-base.httpRequestTool
|
||||
596 templates: n8n-nodes-base.gmail
|
||||
466 templates: n8n-nodes-base.webhook
|
||||
```
|
||||
|
||||
**Comparison**:
|
||||
- Hardcoded task templates: 31 tasks covering 5.9% of nodes
|
||||
- Real templates: 2,646 templates with 2-3k examples for common nodes
|
||||
|
||||
### 3. Database Structure
|
||||
|
||||
```sql
|
||||
CREATE TABLE templates (
|
||||
id INTEGER PRIMARY KEY,
|
||||
workflow_id INTEGER UNIQUE NOT NULL,
|
||||
name TEXT NOT NULL,
|
||||
description TEXT,
|
||||
-- Node information
|
||||
nodes_used TEXT, -- JSON array: ["n8n-nodes-base.httpRequest", ...]
|
||||
workflow_json_compressed TEXT, -- Base64 encoded gzip of full workflow
|
||||
-- Metadata (100% coverage)
|
||||
metadata_json TEXT, -- AI-generated structured metadata
|
||||
-- Stats
|
||||
views INTEGER DEFAULT 0,
|
||||
created_at DATETIME,
|
||||
-- ...
|
||||
);
|
||||
```
|
||||
|
||||
### 4. Real Configuration Examples
|
||||
|
||||
#### HTTP Request Node Configurations
|
||||
|
||||
**Simple URL fetch**:
|
||||
```json
|
||||
{
|
||||
"url": "https://api.example.com/data",
|
||||
"options": {}
|
||||
}
|
||||
```
|
||||
|
||||
**With authentication**:
|
||||
```json
|
||||
{
|
||||
"url": "=https://api.wavespeed.ai/api/v3/predictions/{{ $json.data.id }}/result",
|
||||
"options": {},
|
||||
"authentication": "genericCredentialType",
|
||||
"genericAuthType": "httpHeaderAuth"
|
||||
}
|
||||
```
|
||||
|
||||
**Complex expressions**:
|
||||
```json
|
||||
{
|
||||
"url": "=https://image.pollinations.ai/prompt/{{$('Social Media Content Factory').item.json.output.description.replaceAll(' ','-').replaceAll(',','').replaceAll('.','') }}",
|
||||
"options": {}
|
||||
}
|
||||
```
|
||||
|
||||
#### Webhook Node Configurations
|
||||
|
||||
**Basic webhook**:
|
||||
```json
|
||||
{
|
||||
"path": "ytube",
|
||||
"options": {},
|
||||
"httpMethod": "POST",
|
||||
"responseMode": "responseNode"
|
||||
}
|
||||
```
|
||||
|
||||
**With binary data**:
|
||||
```json
|
||||
{
|
||||
"path": "your-endpoint",
|
||||
"options": {
|
||||
"binaryPropertyName": "data"
|
||||
},
|
||||
"httpMethod": "POST"
|
||||
}
|
||||
```
|
||||
|
||||
### 5. AI-Generated Metadata
|
||||
|
||||
Each template has structured metadata including:
|
||||
|
||||
```json
|
||||
{
|
||||
"categories": ["automation", "integration", "data processing"],
|
||||
"complexity": "medium",
|
||||
"use_cases": [
|
||||
"Extract transaction data from Gmail",
|
||||
"Automate bookkeeping",
|
||||
"Expense tracking"
|
||||
],
|
||||
"estimated_setup_minutes": 30,
|
||||
"required_services": ["Gmail", "Google Sheets", "Google Gemini"],
|
||||
"key_features": [
|
||||
"Fetch emails by label",
|
||||
"Extract transaction data",
|
||||
"Use LLM for structured output"
|
||||
],
|
||||
"target_audience": ["Accountants", "Small business owners"]
|
||||
}
|
||||
```
|
||||
|
||||
## Comparison: Task Templates vs Real Templates
|
||||
|
||||
### Current Approach (get_node_for_task)
|
||||
|
||||
**Pros**:
|
||||
- Curated configurations with best practices
|
||||
- Predictable, stable responses
|
||||
- Fast lookup (no decompression needed)
|
||||
|
||||
**Cons**:
|
||||
- Only 31 tasks (5.9% node coverage)
|
||||
- 28% failure rate (users can't find what they need)
|
||||
- Requires manual maintenance
|
||||
- Static configurations without real-world context
|
||||
- Usage ratio 22.5:1 (search_nodes is preferred)
|
||||
|
||||
### Template-Based Approach
|
||||
|
||||
**Pros**:
|
||||
- 2,646 real workflows with 2-3k examples for common nodes
|
||||
- 100% metadata coverage for semantic matching
|
||||
- Real-world patterns and best practices
|
||||
- Covers 543 node types (103% coverage)
|
||||
- Self-updating (templates fetched from n8n.io)
|
||||
- Rich context (use cases, complexity, setup time)
|
||||
|
||||
**Cons**:
|
||||
- Requires decompression for full workflow access
|
||||
- May contain template-specific context (but can be filtered)
|
||||
- Need ranking/filtering logic for best matches
|
||||
|
||||

### Phase 1: Extract Node Configurations from Templates
|
||||
|
||||
Create a new service: `TemplateConfigExtractor`
|
||||
|
||||
```typescript
|
||||
interface ExtractedNodeConfig {
|
||||
nodeType: string;
|
||||
configuration: Record<string, any>;
|
||||
source: {
|
||||
templateId: number;
|
||||
templateName: string;
|
||||
templateViews: number;
|
||||
useCases: string[];
|
||||
complexity: 'simple' | 'medium' | 'complex';
|
||||
};
|
||||
patterns: {
|
||||
hasAuthentication: boolean;
|
||||
hasExpressions: boolean;
|
||||
hasOptionalFields: boolean;
|
||||
};
|
||||
}
|
||||
|
||||
class TemplateConfigExtractor {
|
||||
async extractConfigsForNode(
|
||||
nodeType: string,
|
||||
options?: {
|
||||
complexity?: 'simple' | 'medium' | 'complex';
|
||||
requiresAuth?: boolean;
|
||||
limit?: number;
|
||||
}
|
||||
): Promise<ExtractedNodeConfig[]> {
|
||||
// 1. Query templates containing nodeType
|
||||
// 2. Decompress workflow_json_compressed
|
||||
// 3. Extract node configurations
|
||||
// 4. Rank by popularity + complexity match
|
||||
// 5. Return top N configurations
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Phase 2: Integrate with Existing Tools
|
||||
|
||||
**Option A**: Enhance `get_node_essentials`
|
||||
- Add `includeExamples: boolean` parameter
|
||||
- Return 2-3 real configurations from templates
|
||||
- Preserve existing compact format
|
||||
|
||||
**Option B**: Enhance `get_node_info`
|
||||
- Add `examples` section with template-sourced configs
|
||||
- Include source attribution (template name, views)
|
||||
|
||||
**Option C**: New tool `get_node_examples`
|
||||
- Dedicated tool for retrieving configuration examples
|
||||
- Query by node type, complexity, use case
|
||||
- Returns ranked list of real configurations
|
||||
|
||||
### Phase 3: Deprecate get_node_for_task
|
||||
|
||||
- Mark as deprecated in tool documentation
|
||||
- Redirect to enhanced tools
|
||||
- Remove after 2-3 version cycles
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Decompression Cost
|
||||
|
||||
- Average compressed size: 6-12 KB
|
||||
- Decompression time: ~5-10ms per template
|
||||
- Caching strategy needed for frequently accessed templates
|
||||
|
||||
### Query Strategy
|
||||
|
||||
```sql
|
||||
-- Fast: Get templates for a node type (no decompression)
|
||||
SELECT id, name, views, metadata_json
|
||||
FROM templates
|
||||
WHERE nodes_used LIKE '%n8n-nodes-base.httpRequest%'
|
||||
ORDER BY views DESC
|
||||
LIMIT 10;
|
||||
|
||||
-- Then decompress only top matches
|
||||
```
|
||||
|
||||
### Caching
|
||||
|
||||
- Cache decompressed workflows for popular templates (top 100)
|
||||
- TTL: 1 hour
|
||||
- Estimated memory: 100 * 50KB = 5MB
|
||||
|
||||
## Impact on P0-R3
|
||||
|
||||
**Original P0-R3 Plan**: Expand task library from 31 to 100+ tasks using fuzzy matching
|
||||
|
||||
**New Approach**: Mine 2,646 templates for real configurations
|
||||
|
||||
**Impact Assessment**:
|
||||
|
||||
| Metric | Original Plan | Template Mining |
|
||||
|--------|--------------|-----------------|
|
||||
| Configuration examples | 100 (estimated) | 2,646+ actual |
|
||||
| Node coverage | ~20% | 103% |
|
||||
| Maintenance | High (manual) | Low (auto-fetch) |
|
||||
| Accuracy | Curated | Production-tested |
|
||||
| Context richness | Limited | Rich metadata |
|
||||
| Development time | 2-3 weeks | 1 week |
|
||||
|
||||
**Recommendation**: PIVOT to template mining approach for P0-R3
|
||||
|
||||
## Implementation Estimate
|
||||
|
||||
### Week 1: Core Infrastructure
|
||||
- Day 1-2: Create `TemplateConfigExtractor` service
|
||||
- Day 3: Implement caching layer
|
||||
- Day 4-5: Testing and optimization
|
||||
|
||||
### Week 2: Integration
|
||||
- Day 1-2: Enhance `get_node_essentials` with examples
|
||||
- Day 3: Update tool documentation
|
||||
- Day 4-5: Integration testing
|
||||
|
||||
**Total**: 2 weeks vs 3 weeks for original plan
|
||||
|
||||
## Validation Tests
|
||||
|
||||
```typescript
|
||||
// Test: Extract HTTP Request configs
|
||||
const configs = await extractor.extractConfigsForNode(
|
||||
'n8n-nodes-base.httpRequest',
|
||||
{ complexity: 'simple', limit: 5 }
|
||||
);
|
||||
|
||||
// Expected: 5 configs from top templates
|
||||
// - Simple URL fetch
|
||||
// - With authentication
|
||||
// - With custom headers
|
||||
// - With expressions
|
||||
// - With error handling
|
||||
|
||||
// Test: Extract webhook configs
|
||||
const webhookConfigs = await extractor.extractConfigsForNode(
|
||||
'n8n-nodes-base.webhook',
|
||||
{ limit: 3 }
|
||||
);
|
||||
|
||||
// Expected: 3 configs showing different patterns
|
||||
// - Basic POST webhook
|
||||
// - With response node
|
||||
// - With binary data handling
|
||||
```
|
||||
|
||||
## Risks and Mitigation
|
||||
|
||||
### Risk 1: Template Quality Varies
|
||||
- **Mitigation**: Filter by views (popularity) and metadata complexity rating
|
||||
- Only use templates with >1000 views for examples
|
||||
|
||||
### Risk 2: Decompression Performance
|
||||
- **Mitigation**: Cache decompressed popular templates
|
||||
- Implement lazy loading (decompress on demand)
|
||||
|
||||
### Risk 3: Template-Specific Context
|
||||
- **Mitigation**: Extract only node configuration, strip workflow-specific context
|
||||
- Provide source attribution for context
|
||||
|
||||
### Risk 4: Breaking Changes in Template Structure
|
||||
- **Mitigation**: Robust error handling in decompression
|
||||
- Fallback to cached configs if template fetch fails
|
||||
|
||||
## Success Metrics
|
||||
|
||||
**Before** (get_node_for_task):
|
||||
- 392 calls, 72% success rate
|
||||
- 28% failure rate
|
||||
- 31 task templates
|
||||
- 5.9% node coverage
|
||||
|
||||
**Target** (template-based):
|
||||
- 90%+ success rate for configuration discovery
|
||||
- 100%+ node coverage
|
||||
- 2,646+ real-world examples
|
||||
- Self-updating from n8n.io
|
||||
|
||||
## Next Steps
|
||||
|
||||
1. ✅ Complete template database analysis
|
||||
2. ⏳ Create `TemplateConfigExtractor` service
|
||||
3. ⏳ Implement caching layer
|
||||
4. ⏳ Enhance `get_node_essentials` with examples
|
||||
5. ⏳ Update P0 implementation plan
|
||||
6. ⏳ Begin implementation
|
||||
|
||||
## Conclusion
|
||||
|
||||
The template database provides a vastly superior alternative to hardcoded task templates:
|
||||
|
||||
- **2,646 templates** vs 31 tasks (85x more examples)
|
||||
- **103% node coverage** vs 5.9% coverage (17x improvement)
|
||||
- **Real-world configurations** vs synthetic examples
|
||||
- **Self-updating** vs manual maintenance
|
||||
- **Rich metadata** for semantic matching
|
||||
|
||||
**Recommendation**: Pivot P0-R3 from "expand task library" to "mine template configurations"

# Comprehensive Integration Testing Plan
|
||||
|
||||
## Overview
|
||||
|
||||
Transform the test suite to test all 17 n8n API handlers against a **real n8n instance** instead of mocks. This plan ensures 100% coverage of every tool, operation, and parameter combination to prevent bugs like the P0 workflow creation issue from slipping through.
|
||||
|
||||
## Critical Requirements
|
||||
|
||||
1. **Credentials**:
|
||||
- Local development: Read from `.env` file
|
||||
- CI/GitHub Actions: Use GitHub secrets (`N8N_URL`, `N8N_API_KEY`)
|
||||
|
||||
2. **Pre-activated Webhook Workflows**:
|
||||
- n8n API doesn't support workflow activation via API
|
||||
- Need pre-created, activated workflows for webhook testing
|
||||
- Store workflow IDs in `.env`:
|
||||
- `N8N_TEST_WEBHOOK_GET_ID` - Webhook with GET method
|
||||
- `N8N_TEST_WEBHOOK_POST_ID` - Webhook with POST method
|
||||
- `N8N_TEST_WEBHOOK_PUT_ID` - Webhook with PUT method
|
||||
- `N8N_TEST_WEBHOOK_DELETE_ID` - Webhook with DELETE method
|
||||
|
||||
3. **100% Coverage Goal**: Test EVERY tool, EVERY operation, EVERY parameter combination
|
||||

|
||||
**Branch**: `feat/integration-tests-workflow-creation`
|
||||
|
||||
**File**: `tests/integration/n8n-api/workflows/create-workflow.test.ts`
|
||||
|
||||
**10+ Test Scenarios**:
|
||||
1. Create workflow with base webhook node (verify P0 bug fix)
|
||||
2. Create workflow with base HTTP request node
|
||||
3. Create workflow with langchain agent node
|
||||
4. Create complex multi-node workflow
|
||||
5. Create workflow with complex connections
|
||||
6. Error: Invalid node type
|
||||
7. Error: Missing required parameters
|
||||
8. Error: Duplicate node names
|
||||
9. Error: Invalid connection references
|
||||
10. Create workflow with custom settings

### Phase 4: Workflow Update Tests (P1)
|
||||
|
||||
**Branch**: `feat/integration-tests-workflow-updates`
|
||||
|
||||
**Files**:
|
||||
- `update-workflow.test.ts` (8+ scenarios)
|
||||
- `update-partial-workflow.test.ts` (30+ scenarios covering all 15 operations)
|

### Phase 5: Workflow Management Tests (P2)
|
||||
|

|
||||
**Files**:

- `delete-workflow.test.ts` (3 scenarios)
|
||||
- `list-workflows.test.ts` (12+ scenarios with all filters and pagination)
|
||||
|
||||
---
|
||||
|
||||
### Phase 6: Validation & Autofix Tests (P2)
|
||||
|
||||
**Branch**: `feat/integration-tests-validation`
|
||||
|
||||
**Files**:
|
||||
- `validate-workflow.test.ts` (16 scenarios: 4 profiles × 4 validation types)
|
||||
- `autofix-workflow.test.ts` (20+ scenarios: 5 fix types × confidence levels)

### Phase 7: Execution Management Tests (P2)
|
||||
|
||||
**Branch**: `feat/integration-tests-executions`
|
||||
|
||||
**Files**:
|
||||
- `trigger-webhook.test.ts` (16+ scenarios: 4 HTTP methods × variations)
|
||||
- `get-execution.test.ts` (20+ scenarios: 4 modes × filters)
|
||||
- `list-executions.test.ts` (10+ scenarios)
|
||||
- `delete-execution.test.ts` (3 scenarios)
|
||||
|
||||
**Special Considerations for Webhook Testing**:
|
||||
- Use pre-activated workflows from `.env`
|
||||
- Each HTTP method uses a different workflow ID
|
||||
- Test both successful triggers and error cases
|
||||
- Verify response data for synchronous executions

|
||||
|
||||
## Test Isolation Strategy
|
||||
|
||||
### Workflow Naming Convention
|
||||
- Prefix: `[MCP-TEST]`
|
||||
- Include test name: `[MCP-TEST] Create Workflow - Base Nodes`
|
||||
- Include timestamp for uniqueness: `[MCP-TEST] Test Name ${Date.now()}`
|
||||
|
||||
### Workflow Tagging
|
||||
- All test workflows tagged with: `mcp-integration-test`
|
||||
- Enables bulk cleanup queries
|
||||
|
||||
### Cleanup Levels
|
||||
1. **Test-level**: After each test via `afterEach` hook
|
||||
2. **Suite-level**: After each test file via `afterAll` hook
|
||||
3. **CI-level**: After CI job completes (always run)
|
||||
4. **Orphan cleanup**: Periodic job to clean up failed test runs
|
||||
|
||||

|
||||
|
||||
**Total New Code:** ~1,520 lines of production-ready TypeScript
|
||||
|
||||
## Next Steps (Phase 2)
|
||||
|
||||
Phase 2 will implement the first actual integration tests:
|
||||
- Create workflow creation tests (10+ scenarios)
|
||||
- Test P0 bug fix (SHORT vs FULL node types)
|
||||
- Test workflow retrieval
|
||||
- Test workflow deletion
|
||||
|
||||
**Branch:** `feat/integration-tests-workflow-creation`
|
||||
|
||||
## Prerequisites for Running Tests
|
||||
|
||||
Before running integration tests, you need to:
|
||||
|
||||
1. **Set up n8n instance:**
|
||||
- Local: `npx n8n start`
|
||||
- Or use cloud/self-hosted n8n
|
||||
|
||||
2. **Configure credentials in `.env`:**
|
||||
```bash
|
||||
N8N_API_URL=http://localhost:5678
|
||||
N8N_API_KEY=<your-api-key>
|
||||
```
|
||||
|
||||
3. **Create 4 webhook workflows manually:**
|
||||
- One for each HTTP method (GET, POST, PUT, DELETE)
|
||||
- Activate each workflow in n8n UI
|
||||
- Set workflow IDs in `.env`:
|
||||
```bash
|
||||
N8N_TEST_WEBHOOK_GET_ID=<workflow-id>
|
||||
N8N_TEST_WEBHOOK_POST_ID=<workflow-id>
|
||||
N8N_TEST_WEBHOOK_PUT_ID=<workflow-id>
|
||||
N8N_TEST_WEBHOOK_DELETE_ID=<workflow-id>
|
||||
```
|
||||
|
||||
See `docs/local/integration-testing-plan.md` for detailed setup instructions.
|
||||
|
||||
## Success Metrics
|
||||
|
||||
Phase 1 Success Criteria - ALL MET:
|
||||
- ✅ All utilities implemented and tested
|
||||
- ✅ TypeScript compiles without errors
|
||||
- ✅ Code follows project conventions
|
||||
- ✅ Comprehensive documentation
|
||||
- ✅ Environment configuration complete
|
||||
- ✅ Cleanup infrastructure in place
|
||||
- ✅ Ready for Phase 2 test implementation
|
||||
|
||||
## Lessons Learned
|
||||
|
||||
1. **N8nApiClient Constructor:** Uses config object, not separate parameters
|
||||
2. **Cursor Handling:** n8n API returns `null` for no more pages, need to convert to `undefined`
|
||||
3. **Workflow ID Validation:** Some workflows might have undefined IDs, need null checks
|
||||
4. **Connection Types:** Error connections need explicit typing to avoid TypeScript errors
|
||||
5. **Webhook Activation:** Cannot be done via API, must be manual - hence pre-activated workflow requirement
|
||||
|
||||
## Time Invested
|
||||
|
||||
Phase 1 actual time: ~2 hours (estimated 2-3 days in plan)
|
||||
- Faster than expected due to clear architecture and reusable patterns
