Test Driven Development
Test-driven development (TDD) is a software development methodology where developers write automated tests before writing the actual code. The tests define the expected behavior of the code, and the code is written to pass those tests. This approach helps ensure that the code meets the required specifications and encourages developers to write code that is testable and maintainable.
TDD follows a simple cycle of writing a failing test, writing the minimum amount of code to make the test pass, and then refactoring the code as needed to improve its quality. This cycle is repeated for each new feature or bug fix. The tests serve as living documentation of the code's behavior and make it easier to catch regressions or breakages when code changes are made.
TDD is a discipline that requires a change in mindset and a focus on quality and correctness, but can result in more robust and maintainable code and can help catch bugs early in the development process.
