You can enforce test-driven development by writing unit, integration, and E2E tests before implementation, then refactoring code until the 80% test coverage threshold is met.

The best way to guide TDD during feature development and refactoring is to generate user journeys and corresponding tests first, then implement code changes until all tests pass and coverage targets are achieved.

Writing tests before implementation requires describing the feature to be added, defining test cases across unit, integration, and E2E scopes, and running them to validate the code changes incrementally.

Yes, you can apply measurable 80%+ test coverage targets to guide bug fixes and API component creation, ensuring tests cover the changes before the implementation logic is finalized.

Test-driven development works for both new features and refactoring cycles by requiring tests to be written first, running them against changes, and refactoring until all tests pass the coverage threshold.

Code refactoring requires unit, integration, and end-to-end tests to maintain software engineering discipline, ensuring that structural changes do not break existing functionality and meet the 80% coverage requirement.
