Crispin and Gregory define Test-Driven Development (TDD) as the process of writing and automating small unit tests before writing the piece of code that will make the test pass. TDD is used for continuous integration testing to ensure small units of code work together first. A unit test verifies the behavior of a small part of the code in the overall system. These tests are the primary candidate for the majority of automated tests. Even teams that are not practicing Agile development use TDD to prevent defects and design software (Agile Testing, 2008).
