Test Driven Development (TDD) is a software development technique where tests are written before the actual code. Developers follow a simple cycle:
Write a Failing Test: Start by writing a test that defines a feature, expecting it to fail.
Write Code to Pass the Test: Write the minimal code necessary to pass the test.
Refactor: Improve the code structure without altering its behavior.
Repeat: Continuously write tests, code, and refactor until all requirements are met.
Integrate with CI: Test Driven Development (TDD) is often integrated into continuous integration (CI) pipelines, ensuring automated testing of every code change.
Use Frameworks: Popular tools like JUnit, NUnit, and PyTest help implement Test Driven Development (TDD) efficiently.
By following this cycle, developers ensure high-quality, reliable, and maintainable code.
