QA Expert

Quality assurance specialist for developing comprehensive testing strategies and quality gates.

When This Skill Activates

Activates when you:

  • Ask for QA strategy
  • Need quality gates
  • Want to improve test coverage
  • Plan testing approach

Quality Assurance Strategy

1. Risk-Based Testing

Prioritize testing based on risk:

Risk Level Testing Approach
Critical (Money, Security, Data) 100% automation, chaos testing
High (Core features) Full E2E, integration, unit
Medium (Secondary features) Integration, unit
Low (Edge features) Unit tests only

2. Testing Pyramid Allocation

Level % of Tests Focus
E2E 10% Critical user journeys
Integration 30% API interactions
Unit 60% Business logic, utilities

3. Quality Gates

Pre-Commit

bash
- Lint: npm run lint
- Format check: npm run format:check
- Type check: npm run type-check
- Unit tests: npm run test:unit

Pre-Merge

bash
- All tests: npm test
- Coverage threshold: > 80%
- Security scan: npm audit
- License check: npm run check:licenses

Pre-Production

bash
- Full test suite: npm run test:all
- E2E tests: npm run test:e2e
- Performance tests: npm run test:perf
- Security audit: npm audit --audit-level high

Test Categories

Functional Testing

Purpose: Verify features work as specified

  • Happy path testing
  • Edge case testing
  • Boundary value analysis
  • Error handling

Non-Functional Testing

Performance

  • Response time < 200ms (p95)
  • Throughput > 1000 req/s
  • Memory usage stable
  • No memory leaks

Security

  • OWASP Top 10 coverage
  • Penetration testing
  • Dependency vulnerability scan
  • Secrets detection

Compatibility

  • Browser testing (Chrome, Firefox, Safari, Edge)
  • Device testing (Mobile, Desktop, Tablet)
  • OS testing (Windows, macOS, Linux)
  • Version testing (N-1 browser versions)

Regression Testing

  • Previous bugs don't reappear
  • New features don't break existing features
  • Performance doesn't degrade

Exploratory Testing

  • Find unexpected issues
  • Test edge cases
  • User experience issues

Quality Metrics

Code Quality

  • Test Coverage: > 80%
  • Cyclomatic Complexity: < 10 per function
  • Code Duplication: < 5%
  • Technical Debt Ratio: < 5%

Defect Metrics

  • Defect Density: < 1 defect per 1000 LOC
  • Critical Defects: 0
  • High Defects: 0
  • Medium Defects: < 3

Test Metrics

  • Test Pass Rate: > 95%
  • Flaky Tests: 0
  • Test Execution Time: < 10 minutes

Automation Strategy

Automate When

  • Test is run frequently
  • Test has deterministic results
  • Test is stable
  • ROI justifies automation cost

Don't Automate When

  • Test requires human judgment
  • Test is exploratory
  • Test is one-time only
  • Test changes frequently
