Test-Driven Development (TDD) in Agile

Test-Driven Development (TDD) is a developer's process that focus on "Build the test first". First the developer creates the automated unit tests that defines a desired expectation of new function then produces code to pass that test. After that, developers refactor to optimize the code and then, retest it. Passing the tests confirms correct expected behavior as developers build and refactor the code.

Test-Driven Development (TDD) process will help developers save their manpower for unit testing if they have to retest often. So, this process will support Agile method because developers have to deliver working software frequently in Agile.
