TDD Cycle

The Test-Driven Development (TDD) cycle is a method for building software efficiently. It starts with writing a small test that checks a specific feature or function. Initially, this test will fail because the feature isn’t created yet. Next, you write just enough code to pass the test. Finally, you refine the code for quality and re-run the test to ensure it works. This cycle—write test, write code, improve—repeats often, helping developers catch issues early, write cleaner code, and build reliable software incrementally.
