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
