Test-driven development for new features requires writing a failing unit test describing expected behavior first, then implementing minimal code to pass the test, and finally refactoring for readability. This red-green-refactor cycle ensures each feature is validated by automated tests from the outset.

The red-green-refactor cycle is a strict test-driven development workflow where you write a failing test first, implement minimal code to make it pass, then clean up the code through refactoring. This discipline reduces defects and enables safe refactors.

Yes, test-driven development applies to bug fixes and refactors across any codebase. You write a failing test that captures the bug or expected behavior, implement the fix until tests pass, and refactor with confidence knowing the automated tests validate your changes.

No specific testing framework is required. Test-driven development can be applied across any codebase where rapid feedback and robust tests are valued. You simply need an environment that supports writing and running unit tests to validate expected behavior.

Writing failing tests before implementation ensures your code is validated by automated tests from the outset. This test-first approach reduces defects, provides rapid feedback, and enables safe refactors by guaranteeing that every feature starts with a verifiable test.

The best way to maintain test quality is following strict red-green-refactor discipline. When adding a new module, first write a failing unit test describing expected behavior, implement until tests pass, then refactor for readability to ensure consistent test quality.
