What is Test Driven Development (TDD)?

🧪

Test Driven Development (TDD)

Test-Driven Development (TDD) is a programming approach that emphasizes writing tests before developing the code functionality. This method ensures that the code meets the intended requirements and helps prevent errors.

Test-Driven Development (TDD) was developed by Kent Beck in the late 1990s as part of Extreme Programming.

Iterative Process

TDD follows a cycle of adding a test, failing the test execution, writing code to pass the test, and then refactoring the code.

🎯

Focus

TDD focuses on testing small units of code at a time, ensuring that the system is built incrementally and with high test coverage.

Refactoring Cycle

Also known as the 'Red-Green-Refactor' cycle, where code is written to make the failed test pass and then refactored to improve its structure.
