Functional Test Suite

Run comprehensive functional testing covering unit, integration, and system tests to validate application functionality.

When to use me

Use this skill when:

• Running complete functional validation before releases
• Setting up CI/CD pipeline with full test coverage
• Testing all functional requirements systematically
• Ensuring code changes don't break existing functionality
• Preparing for QA review or user acceptance testing

What I do

1. Unit Testing Layer

   • Run isolated component tests
   • Validate individual functions and methods
   • Achieve high code coverage (>80%)
   • Mock external dependencies

2. Integration Testing Layer

   • Test component interactions
   • Validate API contracts and data flows
   • Test database and external service integrations
   • Check error handling across boundaries

3. System Testing Layer

   • Test complete end-to-end workflows
   • Validate functional requirements
   • Test user interfaces and interactions
   • Perform smoke and regression testing

Examples

# Run complete functional test suite
npm run test:functional           # Custom functional suite
npm run test                      # Default test command

# Run in CI/CD pipeline
npm run test:ci                   # CI-optimized testing
npm run test:coverage             # With coverage reporting

# Sequential execution
npm run test:unit && npm run test:integration && npm run test:e2e

# Parallel execution (if supported)
npm run test:all --parallel

Output format

Functional Test Suite Results:
──────────────────────────────
Test Pyramid Execution:

Unit Tests (1,234 tests):
  ✅ Passed: 1,230 (99.7%)
  ⚠️ Skipped: 2
  ❌ Failed: 2
  📊 Coverage: 92%

Integration Tests (87 tests):
  ✅ Passed: 85 (97.7%)
  ❌ Failed: 2
    - Database connection pooling
    - Payment gateway timeout

System Tests (23 tests):
  ✅ Passed: 20 (87.0%)
  ❌ Failed: 3
    - User registration flow
    - Checkout process
    - Admin dashboard

Overall: 1,344 tests, 95.2% pass rate
Critical Paths: 15/18 passed (83.3%)
Recommendation: Fix system test failures before release

Notes

• Follow test pyramid principle: many unit tests, fewer integration, even fewer system tests
• Run fast unit tests on every commit
• Run integration tests on pull requests
• Run system tests before releases
• Automate functional testing in CI/CD
• Track test metrics and trends over time
• Use test tags to categorize test types
• Implement flaky test detection and management
