Programmers often reuse designs without questioning their applicability to the task at hand. A program whose design poorly matches its purpose is hard to understand, hard to test, and hard to change. Test-first development guides the design process towards better solutions by keeping it focused on the program’s purpose and highlighting design flaws that lead to poorly defined components and rigid programs.
