test-driven-development

To enforce test-driven development, you must follow a strict Red-Green-Refactor cycle. This means writing a failing test first, implementing minimal code to pass it, and then refactoring. This prevents technical debt and ensures code quality from the start.

Test-driven development requires a failing test first to verify that the test actually checks the intended behavior. This ensures production code is driven by requirements rather than assumptions, satisfying high code quality and regression prevention standards.

Yes, this test-driven development approach applies to all feature development, bug fixes, and refactoring tasks within the software development lifecycle. It enforces behavior-driven design through systematic verification for every code change.

To avoid TDD anti-patterns, you should stop mocking behavior instead of real logic and avoid adding test-only methods to production code. Following a strict Red-Green-Refactor cycle provides guardrails against these common testing mistakes.

To start writing a failing test for a new API endpoint, activate the test-driven development process and define the expected behavior in a test file first. This ensures the implementation is driven by requirements before any production code is written.
