9. **PATCH /workflows/{id}** - NOT IMPLEMENTED
- Purpose: Partial workflow updates
- Status: To be implemented in Story 2.4
### Key Implementation Points
**URL Normalization:**
- All methods benefit from Epic 1's URL normalization (v0.9.1)
- Handles both `/api/v1` included and excluded URLs
**Multi-Instance Pattern:**
All methods follow this pattern:
```typescript
{
instance: {
type: 'string',
description: 'Instance identifier (optional, uses default if not provided)'
}
}
```
**Error Handling:**
- Uses `callWithInstance` pattern from N8NApiWrapper
- Provides detailed error messages with instance context
- Logs errors to stderr via console.error()
**Workflow Structure Transformation:**
- Connections transformed between array format and n8n object format
- Set node parameters normalized (validation.ts)
- See CLAUDE.md:110-135 for connection format details
### Known Issues & Limitations
1. **Manual Trigger Execution Limitation:**
- n8n API v1.82.3 does not support executing manual-trigger workflows via REST API
- execute_workflow tool provides guidance instead of error
- See CLAUDE.md:37-42
2. **Trigger Auto-Addition:**
- activate_workflow may auto-add valid trigger if missing
- Not explicitly documented in n8n API docs
- Needs validation testing
3. **Connection Format:**
- Documentation shows array format
- n8n API expects object format
- Automatic transformation in validation.ts
- Needs thorough testing
### Testing Standards
**Test Framework:**
- Node.js with axios for HTTP requests
- JSON-RPC 2.0 protocol for MCP communication
- Test environment: `http://localhost:3456/mcp`
**Test File Location:**
- Create: `test-workflows-validation.js`
- Integrate with: `test-mcp-tools.js`
**Test Patterns:**
```javascript
const config = {
mcpServerUrl: 'http://localhost:3456/mcp',
healthCheckUrl: 'http://localhost:3456/health',
testWorkflowName: 'Validation Test Workflow',
testFlags: {
runValidationTests: true,
runCleanup: true
}
};
```
**Coverage Requirements:**
- ✅ Positive test cases (happy path)
- ✅ Negative test cases (error scenarios)
- ✅ Edge cases and boundary conditions
- ✅ Multi-instance scenarios
- ✅ Error handling validation
- ✅ Documentation accuracy verification
**Cleanup Strategy:**
- Delete all test workflows after validation
- Use workflow name prefix for easy identification
- Configurable cleanup via `runCleanup` flag
### Validation Checklist Template
For each method, validate:
- [ ] ✅ **Request Format**: Matches documentation
- [ ] ✅ **Response Format**: Matches documentation
- [ ] ✅ **Data Types**: All fields have correct types
- [ ] ✅ **Required Fields**: All required fields present
- [ ] ✅ **Optional Fields**: Optional fields work correctly
- [ ] ✅ **Multi-Instance**: Instance routing works
- [ ] ✅ **Error Handling**: All documented errors tested
- [ ] ✅ **Edge Cases**: Boundary conditions tested
- [ ] ⚠️ **Discrepancies**: Document any differences found

## Testing
### Test Approach
**Phase 1: Individual Method Validation**
- Test each method in isolation
- Validate request/response formats
- Document all findings
**Phase 2: Integration Testing**
- Test method combinations (create → get → update → delete)
- Test workflow lifecycle
- Validate state transitions
**Phase 3: Multi-Instance Testing**
- Test all methods across different instances
- Verify instance isolation
- Test instance routing
**Phase 4: Error Scenario Testing**
- Test all documented error conditions
- Verify error response formats
- Test undocumented edge cases
**Phase 5: Documentation Validation**
- Compare implementation vs documentation
- Identify discrepancies
- Update validation report
### Edge Cases to Test
1. **Empty Workflow List**: Test when no workflows exist
2. **Large Workflow**: Test with 50+ nodes and complex connections
3. **Concurrent Operations**: Test simultaneous create/update/delete
4. **Special Characters**: Test workflow names with Unicode, emojis, special chars
5. **Maximum Size**: Test workflow size limits (if any)
6. **Circular Connections**: Test if circular node connections are allowed
7. **Invalid Node Types**: Test with unsupported node types
8. **Missing Connections**: Test workflows with disconnected nodes
### Testing Frameworks & Patterns
**Test Execution:**
```bash
# Run validation tests
npm run build
npm start & # Start MCP server
node test-workflows-validation.js
```
**Test Structure:**
```javascript
describe('Workflows API Validation', () => {
describe('GET /workflows (list_workflows)', () => {
test('should list all workflows', async () => {
// Test implementation
});
test('should filter by active status', async () => {
// Test implementation
});
// ... more tests
});
// ... more method test suites
});
```

**Bugs Found & Fixed** ✅ (2025-12-26)
1. ✅ **Bug #1 - FIXED**: create_workflow over-strict validation
- Issue: Required non-empty connections array
- Fix: Made nodes and connections optional in `src/index.ts` and `src/utils/validation.ts`
- Result: Minimal workflows can now be created (create_workflow: 3/3 tests passing)
2. ✅ **Bug #2 - FIXED**: list_workflows active filter not working
- Issue: Filter parameter not passed through call chain
- Fix: Implemented active parameter in tool schema, handler, and API wrapper (User contributed this fix)
- Result: Filter by active status now works correctly (list_workflows: 5/5 tests passing)
3. ✅ **Bug #4 - RESOLVED**: activate_workflow/deactivate_workflow not supported by n8n API
- Investigation: Created test script to verify both PUT `/activate` and PATCH `{active: true}` methods
- Finding: n8n API on test server returns 405 Method Not Allowed for both approaches
- Resolution: Not a code bug - API limitation properly handled with informative error messages
- Updated tests to verify correct error handling behavior
- Result: activate_workflow (4/4 tests), deactivate_workflow (2/2 tests) passing
- Documentation: `docs/STORY-2.1-BUG-4-RESOLUTION.md`, `test-activate-methods.js`
**Bugs Fixed (Session 2)** ✅ (2025-12-26)
4. ✅ **Bug #5 - FIXED**: delete_workflow verification error

- Result: delete_workflow 2/2 tests passing, bonus fix for get_workflow 404 test
- Impact: Total coverage improved from 77% to 91%
5. ✅ **Bug #3 - FIXED**: update_workflow parameter format mismatch
- Issue: Test passed nested `{workflow: {...}}` object instead of flat parameters
- Fix: Changed test to pass flat parameters `{id, name}` (lines 749-770)
- Result: update_workflow 2/2 tests passing (100%)
- Impact: Total coverage improved from 91% to 95%
6. ✅ **Bug #6 - FIXED**: execute_workflow 404 handling
- Issue: executeWorkflow always returned success, never checked workflow existence
- Fix: Added workflow existence check before returning API limitation message (src/services/n8nApiWrapper.ts lines 259-307)
- Result: execute_workflow 2/2 tests passing (100%)
- Impact: Total coverage improved from 95% to 100% ✅
