• Load Testing: Using Artillery.js
• Test Scenarios:
  • API Health Check (20% weight)
  • Get Latest Blocks (30% weight)
  • Search Functionality (25% weight)
  • Chain Stats (25% weight)
• Test Phases:
  • Warm up: 60s @ 10 req/s
  • Load test: 120s @ 50 req/s
  • Stress test: 60s @ 100 req/s
• Metrics: Response times, success rates, error rates
• Reports: HTML and JSON performance reports

4. Security Scan (security.yml)

Triggers: Push/PR to main/develop, scheduled weekly Purpose: Security vulnerability detection and monitoring

Features:

• NPM Audit: Dependency vulnerability scanning
• Snyk: Advanced security scanning (requires SNYK_TOKEN)
• CodeQL: Static code analysis for security issues
• TruffleHog: Secret detection in code
• OWASP ZAP: Web application security testing (PR only)
• SARIF Upload: Integration with GitHub Security tab

🔧 Setup Requirements

Required Secrets

Add these secrets to your GitHub repository settings:

🚨 Troubleshooting

Common Issues

1. Test Failures

• Check test logs in Actions tab
• Unit test failures are often mocking issues (non-critical)
• Integration/E2E test failures indicate real issues

2. Security Scan Failures

• Review security report artifacts
• Address high/critical vulnerabilities
• Update dependencies regularly

3. Performance Degradation

• Compare with previous performance reports
• Check for resource-intensive changes
• Review database query performance

4. Build Failures

• Check TypeScript compilation errors
• Verify all dependencies are installed
• Review environment variable requirements

Getting Help

1. Check workflow logs in GitHub Actions tab
2. Review artifact reports for detailed information
3. Compare with previous successful runs
4. Check for recent dependency updates

🔄 Continuous Improvement

Planned Enhancements

• Database integration testing with test containers
