To implement a red-green-refactor cycle, write a failing test for the desired behavior, add the minimal code required to pass it, then refactor to improve quality while preserving test coverage.

The best way to maintain high test coverage is to drive feature development with tests, adhere to a strict red-green-refactor cycle, and track progress against a minimum 80% coverage target.

Yes, you can use test-driven development for refactoring tasks across existing codebases by writing tests first to validate design and ensure features remain reliable throughout the structural changes.

Writing tests first improves reliability and maintainability by ensuring features are designed and implemented through tests, which enforces clear test design practices and validates behavior before deployment.

Limitations of enforcing a strict test-driven development workflow include the discipline required to consistently write failing tests first and the overhead of maintaining an 80% coverage target during rapid feature development cycles.
