TDD stands for Test-Driven Development. It is a software development approach where developers write automated tests before writing the actual code. The idea is to first define what the software should do by writing a test that will fail, then write the code to make the test pass, and finally refactor the code to make it more efficient or maintainable.

The TDD process typically follows these steps:

1. Write a test: Start by writing a test that describes the expected behavior of the software. This test should fail initially because the code hasn't been written yet.

2. Write the code: Write the minimum amount of code necessary to make the test pass. Don't worry about making the code efficient or elegant at this stage, as the goal is simply to get the test to pass.

3. Refactor: Once the test passes, refactor the code to make it more efficient, readable, and maintainable.

4. Repeat: Repeat the process by writing another test and then following steps 2 and 3.

TDD has several benefits, including:

• Improved code quality: By writing tests first, developers can ensure that the code meets the expected behavior, reducing the likelihood of bugs and errors.

• Faster feedback: TDD provides rapid feedback on code changes, making it easier to catch and fix problems early in the development process.

• Easier maintenance: TDD makes it easier to maintain and modify code over time because the tests serve as a safety net, preventing unintended consequences of changes.

• Better collaboration: TDD encourages collaboration between developers, testers, and stakeholders by providing a clear definition of the expected behavior of the software.
