Test-driven development (TDD) is a technique that helps you write better code, faster and with more confidence. It emphasizes writing automated tests before writing the code. Here’s the process:
- Create a test that fails because the code doesn’t exist yet.
- Write the minimum amount of code necessary to make the test pass.
- Refactor the code to make it more maintainable and efficient.
- Repeat the process until your code meets the desired behaviors.
