Test-Driven Development and Behavior-Driven Development
Test-Driven Development and Behavior-Driven Development Test-Driven Development (TDD) and Behavior-Driven Development (BDD) are practical ideas to improve software quality. TDD asks developers to write tests before implementing code. The process follows a red-green-refactor loop: write a failing test, make it pass, then clean up. This discipline helps keep functions small, clear, and well tested, and it often reveals design choices early. BDD shifts the focus from code to behavior. It asks, “What should the user experience be?” and uses plain language to describe scenarios. Teams write stories in everyday terms and translate them into concrete acceptance criteria. The result is documentation that participants from product, QA, and development can read and agree on. BDD makes sure the feature delivers real value, not just technically correct snippets. ...
