TDD practices

Test-Driven Development (TDD) is a software approach where programmers write small tests for specific features before creating the actual code. These tests verify the intended behavior. Once a test is written, the developer writes just enough code to pass it, then refines the code for quality. This cycle repeats, ensuring the software works as expected and making it easier to identify and fix issues early. TDD promotes reliable, maintainable code and helps developers understand the requirements clearly from the outset.
