feat: implement integration testing foundation (Phase 1)
Complete implementation of Phase 1 foundation for n8n API integration tests. Establishes core utilities, fixtures, and infrastructure for testing all 17 n8n API handlers against real n8n instance. Changes: - Add integration test environment configuration to .env.example - Create comprehensive test utilities infrastructure: * credentials.ts: Environment-aware credential management (local .env vs CI secrets) * n8n-client.ts: Singleton API client wrapper with health checks * test-context.ts: Resource tracking and automatic cleanup * cleanup-helpers.ts: Multi-level cleanup strategies (orphaned, age-based, tag-based) * fixtures.ts: 6 pre-built workflow templates (webhook, HTTP, multi-node, error handling, AI, expressions) * factories.ts: Dynamic node/workflow builders with 15+ factory functions * webhook-workflows.ts: Webhook workflow configs and setup instructions - Add npm scripts: * test:integration:n8n: Run n8n API integration tests * test:cleanup:orphans: Clean up orphaned test resources - Create cleanup script for CI/manual use Documentation: - Add comprehensive integration testing plan (550 lines) - Add Phase 1 completion summary with lessons learned Key Features: - Automatic credential detection (CI vs local) - Multi-level cleanup (test, suite, CI, orphan) - 6 workflow fixtures covering common scenarios - 15+ factory functions for dynamic test data - Support for 4 HTTP methods (GET, POST, PUT, DELETE) via pre-activated webhook workflows - TypeScript-first with full type safety - Comprehensive error handling with helpful messages Total: ~1,520 lines of production-ready code + 650 lines of documentation Ready for Phase 2: Workflow creation tests 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

# 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
|
||||
|

## Implementation Phases
|

### Phase 1: Foundation (Branch: `feat/integration-tests-foundation`)
|
||||
|
||||
#### 1.1 Environment Configuration
|
||||
|
||||
**Update `.env.example`:**
|
||||
```bash
|
||||
# ========================================
|
||||
# INTEGRATION TESTING CONFIGURATION
|
||||
# ========================================
|
||||
|
||||
# n8n API Configuration for Integration Tests
|
||||
N8N_API_URL=http://localhost:5678
|
||||
N8N_API_KEY=your-api-key-here
|
||||
|
||||
# Pre-activated Webhook Workflows for Testing
|
||||
# Create these workflows manually in n8n and activate them
|
||||
# Each workflow should have a single Webhook node with the specified HTTP method
|
||||
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
|
||||
|
||||
# Test Configuration
|
||||
N8N_TEST_CLEANUP_ENABLED=true # Enable automatic cleanup
|
||||
N8N_TEST_TAG=mcp-integration-test # Tag for test workflows
|
||||
N8N_TEST_NAME_PREFIX=[MCP-TEST] # Name prefix for test workflows
|
||||
```
|
||||
|
||||
**GitHub Secrets (for CI):**
|
||||
- `N8N_URL`: n8n instance URL
|
||||

|
||||
- `N8N_TEST_WEBHOOK_GET_ID`: Pre-activated GET webhook workflow ID
|
||||
- `N8N_TEST_WEBHOOK_POST_ID`: Pre-activated POST webhook workflow ID
|
||||
- `N8N_TEST_WEBHOOK_PUT_ID`: Pre-activated PUT webhook workflow ID

### Phase 2: Workflow Creation Tests (P0)
|
||||
|
||||
**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 3: Workflow Retrieval Tests (P1)
|
||||
|
||||
**Branch**: `feat/integration-tests-workflow-retrieval`

||||
|
||||
**Files**:
|
||||
- `get-workflow.test.ts` (3 scenarios)
|
||||
- `get-workflow-details.test.ts` (4 scenarios)
|
||||
- `get-workflow-structure.test.ts` (2 scenarios)
|
||||
- `get-workflow-minimal.test.ts` (2 scenarios)
|
||||
|
||||
---
|
||||
|
||||
### 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)
|
||||
|
||||
**Branch**: `feat/integration-tests-workflow-management`
|
||||
|
||||
**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`

|
||||
- `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
|
||||

|
||||
|
||||

|
||||
|
||||
## Notes
|
||||
|
||||
- Each phase should be developed on a separate branch
|
||||
- Phases can be parallelized where dependencies allow
|
||||
- Run local tests frequently to catch issues early
|
||||
- Document any n8n API quirks discovered during testing
