test-driven-development

Enforce a test-first approach by mandating that no production code is written without a preceding failing test. This methodology guarantees verifiable code quality and prevents regressions by ensuring tests precede implementation for all new features.

The Red-Green-Refactor cycle is a test-driven development process where you write a failing test, implement minimal code to pass that test, and finally refactor the code while ensuring all tests remain green.

Write tests before code for bug fixes and refactoring by first creating a failing test that captures the bug or desired behavior. You then write minimal production code to pass the test, ensuring the refactoring does not introduce regressions.

Yes, this test-driven development approach works for user authentication endpoints. You write a failing test for successful login, implement minimal code to pass the test, and refactor while ensuring all tests remain green.

You should write a failing test before production code to adhere to the iron law of test-driven development. This ensures your tests are actually verifying the new feature and prevents writing unnecessary implementation code.

The best way to prevent software regressions during refactoring is to follow the test-driven development cycle. You write tests first, implement minimal code to pass them, and refactor only while ensuring all existing tests remain green.
