Definition
Test-Driven Development (TDD) is a software development methodology where tests are written before writing the code they are testing. The process follows a short development cycle of writing a test, making it pass, and refactoring.
Process
The TDD process includes writing a test for a specific functionality, writing the minimum code to pass the test, and then refactoring the code to meet standards.
Benefits
Benefits of TDD include improved code quality, fewer bugs, clearer code, and a well-documented codebase.
