test-driven-development

Test-driven development uses the red-green-refactor cycle by writing a failing test first, implementing minimal production code to make it pass, and then refactoring while ensuring the test stays green. This loop guides design decisions and prevents regressions.

Yes, test-driven development is applicable to both frontend and backend workloads. It guides teams through writing failing tests first for new features, bug fixes, and refactors, ensuring software quality across the entire stack.

The best way to start test-driven development is to write a failing test that represents the desired behavior, then implement the minimal code required to make that test pass. This ensures focused tests that document expected behavior.

You need test-driven development for bug fixes and refactoring when you want to catch defects early and prevent regressions. By writing failing tests first, you align tests with intended behavior before changing production code.

Writing meaningful tests in test-driven development documents expected behavior and guides design decisions, while maintaining minimal production code ensures your implementation stays focused on passing the test without unnecessary complexity.
