- Create benchmark test suites for critical operations: - Node loading performance - Database query performance - Search operations performance - Validation performance - MCP tool execution performance - Add GitHub Actions workflow for benchmark tracking: - Runs on push to main and PRs - Uses github-action-benchmark for historical tracking - Comments on PRs with performance results - Alerts on >10% performance regressions - Stores results in GitHub Pages - Create benchmark infrastructure: - Custom Vitest benchmark configuration - JSON reporter for CI results - Result formatter for github-action-benchmark - Performance threshold documentation - Add supporting utilities: - SQLiteStorageService for benchmark database setup - MCPEngine wrapper for testing MCP tools - Test factories for generating benchmark data - Enhanced NodeRepository with benchmark methods - Document benchmark system: - Comprehensive benchmark guide in docs/BENCHMARKS.md - Performance thresholds in .github/BENCHMARK_THRESHOLDS.md - README for benchmarks directory - Integration with existing test suite The benchmark system will help monitor performance over time and catch regressions before they reach production. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

# 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
|
|
[](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
