🎯 Key Features

Graceful Degradation

  • ✅ All tests pass regardless of plugin availability
  • ✅ Plugins installed → Use plugins, test performance
  • ✅ Plugins missing → Use HTTP/SOPS fallback, warn user
  • ✅ Services unavailable → Skip service-dependent tests, report status

Performance Monitoring

  • ✅ Plugin mode: <50ms (excellent)
  • ✅ HTTP fallback: <200ms (good)
  • ✅ SOPS fallback: <500ms (acceptable)

Comprehensive Reporting

  • ✅ Colored console output with progress indicators
  • ✅ JSON report generation for CI/CD
  • ✅ Performance analysis with baselines
  • ✅ Failed test details with error messages
  • ✅ Environment information (Nushell version, OS, arch)

CI/CD Integration

  • ✅ GitHub Actions workflow ready
  • ✅ Multi-platform testing (Ubuntu, macOS)
  • ✅ Artifact uploads (reports, logs, benchmarks)
  • ✅ Manual trigger support

🔍 Test Philosophy

No Hard Dependencies

Tests never fail due to:

  • ❌ Missing plugins (fallback tested)
  • ❌ Services not running (gracefully reported)
  • ❌ Network issues (error handling tested)

Always Pass Design

  • ✅ Tests validate behavior, not availability
  • ✅ Warnings for missing features
  • ✅ Errors only for actual test failures

Performance Awareness

  • ✅ All tests measure execution time
  • ✅ Performance compared to baselines
  • ✅ Reports indicate plugin vs fallback mode

🛠️ Configuration

Plugin Configuration File

Location: provisioning/config/plugin-config.toml

Key sections:

  • Global: plugins.enabled, warn_on_fallback, log_performance
  • Auth: Control center URL, token refresh, MFA settings
  • KMS: Preferred backend, fallback, multiple backend configs
  • Orchestrator: URL, data directory, workflow settings
  • Performance: Connection pooling, HTTP client, caching
  • Security: TLS verification, certificates, cipher suites
  • Logging: Level, format, file location
  • Metrics: Collection, export format, update interval

🎓 Lessons Learned

Design Decisions

  1. Graceful Degradation First: Tests must work without plugins
  2. Performance Monitoring Built-In: Every test measures execution time
  3. Comprehensive Reporting: JSON + console output for different audiences
  4. CI/CD Ready: GitHub Actions workflow included from day 1
  5. No Hard Dependencies: Tests never fail due to environment issues

Best Practices

  1. Use std assert: Standard library assertions for consistency
  2. Complete blocks: Wrap all operations in (do { ... } | complete)
  3. Clear test names: test_<feature>_<aspect> naming convention
  4. Both modes tested: Plugin and fallback tested in each test
  5. Performance baselines: Documented expected performance ranges

🔮 Future Enhancements

Potential Additions

  1. Stress Testing: High-load concurrent access tests
  2. Security Testing: Authentication bypass attempts, encryption strength
  3. Chaos Engineering: Random failure injection
  4. Visual Reports: HTML/web-based test reports
  5. Coverage Tracking: Code coverage metrics
  6. Regression Detection: Automatic performance regression alerts
