test-driven-development

To enforce test-driven development, apply a strict Red-Green-Refactor cycle that requires writing a failing test before any production code. This workflow ensures every feature is verified, preventing bias and guaranteeing regression-proof implementation.

The best way to prevent testing anti-patterns when fixing bugs is to follow a comprehensive guide that avoids mocking real behavior and polluting production code with test-only methods. This ensures reliable regression prevention and high code quality.

Yes, you need a standard testing harness like Jest or Vitest to execute the Red-Green-Refactor cycle. These frameworks provide the necessary environment to run failing tests first and verify the minimal production code that follows.

Test-first discipline prevents over-engineered code by enforcing a rigorous Red-Green-Refactor cycle that ensures every feature is verified by a failing test. This structured workflow guarantees the final solution is minimal and strictly addresses the requirement.
