The main advantage of TDD lies in its ability to catch issues early in the development process. Because tests are written before the code, developers gain immediate feedback on whether their implementation meets the specified requirements. This approach leads to more reliable and maintainable code. However, TDD requires a mindset shift for many developers and may initially slow down the development pace as writing tests and code iteratively takes discipline and practice. https://testomat.io/blog/atdd-vs-tdd-understanding-the-key-differences/
