Test-driven Development (TDD) is a software development methodology that involves writing tests for a software system before writing the actual code for the system. The tests are used to define the desired behavior of the system, and are used to guide the development of the code.

The main goal of TDD is to improve the quality and reliability of a software system. By writing tests before writing the code, developers can ensure that the code they write meets the desired specifications, and that it is free of bugs and other defects. This can help to prevent problems and defects from being introduced into the code later on in the development process, which can save time and resources.

TDD also encourages a more iterative and incremental approach to software development. Instead of trying to write all of the code for a system at once, TDD involves writing small, focused pieces of code that pass the tests that have been written. This can make the development process more manageable and can help to reduce the risk of errors and defects.

In addition to improving the quality and reliability of a software system, TDD can also make the development process more efficient. By using tests to guide the development process, developers can avoid spending time writing code that does not meet the desired specifications, or that does not work as intended. This can help to save time and resources, and can make the development process more efficient overall.

Overall, TDD is a valuable tool for improving the quality and reliability of a software system, and for making the development process more efficient. By writing tests before writing the code, developers can ensure that the code they write meets the desired specifications, and can avoid spending time on code that does not work as intended.
