Write strategic, minimal tests focusing on core user flows and critical paths, deferring edge cases and implementation details until dedicated testing phases. Use this skill when adding test files for features after implementation is complete, when writing unit tests for critical business logic, or when creating integration tests for primary user workflows. Use this skill when working with test files in tests/, __tests__/, specs/, or similar test directories. Use this skill when using testing frameworks like Jest, pytest, RSpec, or Vitest, when mocking external dependencies, or when deciding test coverage priorities. Use this skill when writing tests that focus on behavior rather than implementation details, keeping tests fast and maintainable.
