tdd-workflow

To enforce the RED-GREEN-REFACTOR cycle during test-driven development, this workflow guarantees a failing test precedes production code, requires minimal changes to pass it, and then permits safe refactoring without altering behavior.

The best way to apply test-driven development to bug fixes with regression risk is using a workflow that requires writing a failing regression test before implementing the smallest production code change necessary to make it pass.

You need a test-first approach for new feature development, refactoring tasks requiring test coverage, and bug fixes with regression risk to reduce missed tests and ensure a failing test always exists before production code changes.

To start coding with a TDD workflow for new feature development, begin by writing a failing test, implement the smallest code snippet required to pass that test, and then refactor the code while keeping all tests green.

Yes, this TDD workflow supports refactoring tasks by enforcing test coverage first, ensuring you write tests before changes and allowing safe refactoring only after achieving a green test state without changing behavior.

Test-driven development imposes minimal production changes until tests pass to strictly enforce the RED-GREEN-REFACTOR cycle, preventing over-engineering and reducing regression risk by ensuring code strictly meets test requirements.
