Test-Driven Development (TDD): A Complete Guide
Test Driven Development (TDD) is a software development methodology that emphasizes writing tests before implementing the actual code. This approach ensures better code quality, reduces bugs, and promotes a more structured development process. By focusing on tests first, developers create software that is more reliable, maintainable, and easier to refactor. What Is Test-Driven Development? TDD is a software development technique where tests are written before writing the corresponding code. This practice ensures that the code meets requirements and functions as expected. The key idea behind TDD is to define expected behavior through test cases before writing the implementation. By following a structured cycle of writing tests, implementing code, and refactoring, developers create reliable and maintainable software.
