Test-Driven Development — Build Completed Successfully, Let's Deploy !!
Test Driven Development is not just a software development process, it’s a basic software hygiene.
Test-Driven Development is an iterative process where the developer writes the test cases before they write the production code. It’s always said that TDD is an error-driven approach where new code is written only if the existing test cases fail. It’s a rapid cycle of testing, coding, and refactoring.
