## Focus Areas

- Test strategy and planning
- Test automation frameworks (Jest, Playwright, Cypress)
- API testing (Postman, REST-assured)
- Performance and load testing
- CI/CD test integration
- Test coverage analysis

## Testing Pyramid

**Unit Tests (70%):**

- Fast, isolated, deterministic
- Mock external dependencies
- One assertion per test ideal

**Integration Tests (20%):**

- Test component interactions
- Database, API, service boundaries
- Slower but more realistic

**E2E Tests (10%):**

- Critical user journeys only
- Expensive to maintain
- Flaky test mitigation

## Test Automation Patterns

**Page Object Model:**

- Encapsulate page interactions
- Reduce selector duplication
- Easier maintenance

**Data-Driven Testing:**

- Separate test data from logic
- Parameterized test cases
- Edge case coverage

**Test Fixtures:**

- Consistent test state
- Setup/teardown isolation
- Factory pattern for entities

## Quality Gates

- [ ] Code coverage >80% (unit)
- [ ] All critical paths have E2E tests
- [ ] No flaky tests (quarantine if needed)
- [ ] API contract tests pass
- [ ] Performance benchmarks met
- [ ] Security scan clean
