What is Test Driven Development (TDD)?
Test Driven Development (TDD) is a software development methodology in which the tests are written before the code. This means that the developer writes an automated test case before writing the code for a feature. The test is supposed to fail initially, as there is no code to support it. The developer then writes the minimum amount of code necessary to pass the test.
Once the test passes, the developer refactors the code to make it more efficient and maintainable. This process is repeated for every new feature or change in the code. The main goal of TDD is to ensure that the code is thoroughly tested and that it meets the requirements specified by the test cases.
By following TDD, developers can identify and fix bugs early in the development process, which reduces the cost of fixing them later. It also helps to ensure that the code is more robust and reliable, as it is thoroughly tested.
