Test-Driven Development (TDD) is a software development approach in which developers write automated test cases before implementing the actual code. The basic idea behind TDD is to write a failing test case first and then write the code that passes the test. This helps to ensure that the code is correct, complete, and maintainable.
TDD involves a cycle of three steps:
1. Red: Write a test case that fails.
2. Green: Write the code to make the test case pass.
3. Refactor: Clean up the code to ensure it is maintainable.
The benefits of TDD include:
1. Helps to ensure that the code meets the requirements and works as expected.
2. Facilitates better design as developers think about the code from the perspective of the user.
3. Allows for easier maintenance and refactoring of the code.
4. Increases confidence in the code, reducing the likelihood of bugs and errors.
TDD is commonly used in agile software development methodologies and is becoming increasingly popular in the industry.
