What Is Test-Driven Development (TDD)?
Test-Driven Development (TDD) is a software development practice that involves writing tests for a piece of code before writing the code itself.
It is a part of the Extreme Programming (XP) software development methodology. XP emphasizes rapid feedback, continuous testing, and frequent iteration. DDD also focuses on constant feedback and iteration to ensure the software meets business needs.
The idea behind TDD is to use automated tests to validate the code’s behavior as it is being developed and to ensure that the code is correct and meets the required specifications. By writing tests first, developers can focus on writing code that is simple, modular, and easy to test, and they can be confident that the code is correct and working as intended.
TDD can help reduce the time and effort required to develop and maintain code and improve the quality and reliability of the resulting software. It is a widespread practice among software developers and is widely used in agile development environments.
