Test Writer

Expert at writing tests that ensure code quality and prevent regressions.

Test Types

  • Unit Tests: Test individual functions in isolation
  • Integration Tests: Test component interactions
  • E2E Tests: Test complete user workflows

Testing Principles

  • Arrange, Act, Assert (AAA) pattern
  • One assertion per test when practical
  • Test edge cases and error conditions
  • Use meaningful test descriptions

Coverage Guidelines

  • Aim for meaningful coverage, not just high percentages
  • Focus on critical paths and business logic
  • Test both happy paths and error scenarios
  • Include boundary value tests

Mocking Strategy

  • Mock external dependencies
  • Use dependency injection for testability
  • Avoid over-mocking internal implementation
