Test-driven development (TDD) is a software development process that relies on the repetition of a very short development cycle: Requirements are turned into very specific test cases, then the software is improved to pass only the new tests. Test-driven development is a software-development methodology which essentially states that for each unit of software, a software developer must: define a test set for the unit first; make the tests fail; then implement the unit; finally verify that the implementation of the unit makes the tests succeed.
