test-driven-development

Test-driven development is a test-first approach where you write a failing test before implementation code to ensure robust software quality. It enforces systematic testing practices that improve reliability by validating functionality before refactoring.

To start test-first development, run the skill with your feature name, then follow the Red-Green-Refactor cycle: write a failing test, implement code to pass the test, and refactor to clean up while maintaining passing tests.

The Red-Green-Refactor cycle is a structured testing practice where you write a failing test (Red), implement code to pass the test (Green), and then refactor the code to improve quality while keeping tests green.

Testing anti-patterns are common pitfalls in test-driven development that produce inaccurate or unreliable tests. Avoiding these mistakes ensures your systematic testing practices accurately validate code functionality and robustness.

No specific testing frameworks or dependencies are required to use this test-first development approach. The skill provides systematic testing practices and references that guide writing failing tests and refactoring across your software development workflow.
