Test-Driven Development (TDD)
Test-Driven Development (TDD) is a software development approach where tests for a new feature are written before the actual code. First, a developer creates a test that defines how the feature should work. Since the feature isn’t implemented yet, the test will initially fail. The developer then writes just enough code to pass the test. This process is repeated, with additional tests leading to further code development. TDD helps ensure that software is reliable and works as intended, encouraging better design and making it easier to catch errors early in the development process.

Test-driven Development (TDD) is a software development process where developers first write tests for new features before creating the actual code. The process follows three main steps: write a test that defines a desired function, run the test to see it fail (since the function isn’t implemented yet), and then write the code needed to pass the test. Finally, developers refactor the code for optimization while ensuring all tests still pass. This approach helps ensure that the code meets requirements, reduces bugs, and encourages better design through continuous testing and feedback during the development process.
