Testing Test Writing

Write minimal, strategic tests focused on core user flows and critical paths rather than comprehensive coverage. When creating or modifying test files for unit tests, integration tests, or end-to-end tests. When working on test files (*.test.ts, *.spec.ts, __tests__/*). When writing tests for critical user workflows and primary functionality. When testing behavior rather than implementation details. When mocking external dependencies or ensuring fast test execution. When deciding which parts of the codebase require testing coverage.
