Description: The ‘Red-Green-Refactor’ cycle is a fundamental approach in Test-Driven Development (TDD) used to ensure software quality. This cycle consists of three stages: first, a test is written that initially fails, known as ‘red’. This phase is crucial as it sets expectations for the behavior of the code to be developed. Next, the necessary code is implemented to make the test pass, referred to as ‘green’. This stage involves writing code that meets the test requirements, ensuring the software functions as expected. Finally, in the ‘refactor’ phase, the existing code is improved without altering its functionality, aiming to optimize its structure and readability. This cycle is continuously repeated, promoting an iterative and agile development process. The ‘Red-Green-Refactor’ methodology not only helps detect errors early but also fosters a better understanding of the problem to be solved, resulting in cleaner and more maintainable code. This approach has gained popularity in the software development community as it allows teams to work more efficiently and effectively, ensuring the final product meets desired quality standards.
