Test-driven development (TDD) is a development methodology focused on writing tests before writing code. The purpose of TDD is to prevent bugs from being introduced into code and to help developers think about the design of their code before they write it.

TDD is an iterative process that consists of the following steps:

1. Write a test
2. Run the test and see it fail
3. Write code to make the test pass
4. Refactor the code
5. Repeat from step 1

The benefits of TDD include improved code quality and design, as well as reduced debugging time. However, TDD can be time-consuming and may not be suitable for all projects.

TDD is a development methodology which focuses on writing tests first, before writing the actual code. This allows for better code coverage and helps to ensure that all code is properly tested.

To implement TDD, first write a test case for the functionality you want to add. Then write the code to make the test pass. Finally, refactor the code as needed.
