Test Driven Development (TDD) is a software development process in which the developer must first write a test for a feature, and then write the code to make the test pass. This allows for more thorough testing of new features and code, and faster and more reliable development in general.

TDD follows the concept of "red-green-refactor" where code is first written to make the test fail, then written to make the test pass, and finally refactored to ensure the code is clean and best practices are followed. Every test should cover a single unit of functionality and each should be independent of other tests.
