Process of applying TDD to a NextJS project
Introduction Test-Driven Development (TDD) is an advanced software development methodology where tests are written before the actual source code is implemented. This process operates in a repetitive cycle: Red (Write a failing test) -> Green (Write the minimum source code to make the test pass) -> Refactor (Optimize the code structure). Advantages : Improve source code quality: Minimize potential bugs right from the initial development phase. Better system design: Thinking about testing first helps you build highly modular, loosely coupled and easy-to-maintain modules. Confident Refactoring: You can comfortably improve and optimize code without fear of breaking existing features, thanks to the automated test system protection. Living documentation: Test cases act as precise specification documentation, helping team members clearly understand how the system operates. Reduce Debugging Time : TDD helps detect errors right at the moment "just finished typing". The c...
