Unit testing is a component of test-driven development (TDD), a pragmatic methodology that takes a meticulous approach to build a product by means of continual testing and revision. In TDD, test cases are initially created by the developer before they start developing their application. This method of test can be applied virtually to every level of software testing: unit, integration, system and acceptance.
