Test-driven development (TDD) is a software development methodology that involves converting “each component of the application into a test case before it is built and then testing and tracking the component repeatedly,” explains Chiradeep BasuMallick.
Through this iterative approach, BasuMallick says, “testing, coding, and reworking are done in fast succession. The first step in test-driven development is to plan and create tests for each minor aspect of an application’s functionality. The test-driven development framework tells programmers to build new code only in the event that an automated test fails.”
This article describes the TDD process along with its benefits and limitations.
