TDD is the idea that, before you write any code, you write a test that acts as a specification for exactly what that code is supposed to do. After creation, developer will start implement those features. In both cases, the developer writes the test before writing the code to make the test pass.

First, the tester writes an automated test case which defines the desired function that the system should ideally perform, but purposely designs the test case in such a way that it cannot be fulfilled by the system in its present state. Test-driven development (TDD) is a software development process that relies on the repetition of a very short development cycle: first the developer writes an (initially failing) automated test case that defines a desired improvement or new function, then produces the minimum amount of code to pass that test, and ⦠This process is a great way to approach most development work, but sometimes it might not make sense. The fact that it uses tests for this does not make it a testing practice.
