To enforce test-first development, you must write a failing test that defines expected behavior before implementing any production code. This approach prevents scope creep and ensures requirements are met upfront.

The Red-Green-Refactor workflow is a test-first process where you write a failing test, implement minimal code to pass it, and then clean up the code. It ensures deterministic execution and prevents regressions.

To start using TDD for bug fixes and refactoring, write a failing test that captures the expected behavior, run it to observe the failure, implement the minimal code to pass, and then refactor safely.

Yes, test-first development requires deterministic execution to effectively prevent regressions. Enforced verification steps ensure your tests reliably validate correct behavior before and after refactoring.

The best way to structure feature work and prevent scope creep is to define expected behavior upfront by writing failing tests. This test-first approach ensures you implement only the minimal code required to pass.

You should reconsider the Red-Green-Refactor testing workflow if your environment lacks support for deterministic test execution or if you cannot establish mandatory failing tests before writing production code.
