Test-driven development (TDD) is a software development approach that is commonly used in Agile Development. It is a process where developers write automated tests before writing the actual code. The main idea behind TDD is to ensure that the code meets the desired requirements and functions correctly.
In TDD, the development process typically follows these steps:
1. Write a test: The developer writes a test case that defines the desired behavior or functionality of the code. This test is initially expected to fail since the code has not been implemented yet.
2. Run the test: The developer runs the test to confirm that it fails, as expected. This step ensures that the test is correctly written and that it is indeed testing the desired functionality.
3. Write the code: The developer writes the minimum amount of code required to pass the test. The focus is on making the test pass, rather than writing the entire functionality at once.
4. Run all tests: After writing the code, the developer runs all the tests, including the newly added one. This step ensures that the new code did not break any existing functionality.
5. Refactor the code: If necessary, the developer refactors the code to improve its design, readability, or performance. This step is crucial to maintain the code quality and ensure its long-term maintainability.
6. Repeat the process: The developer repeats the above steps for each new functionality or requirement, continuously adding new tests and code.
TDD in Agile Development offers several benefits. It helps in creating a comprehensive suite of tests that act as documentation for the codebase. It also promotes better code quality, as developers are forced to think about the design and functionality before writing the code.
