In TDD, what is the typical order of steps for writing and testing code?

  • Refactor, write code, write tests
  • Write code, write tests, refactor
  • Write tests, refactor, write code
  • Write tests, write code, refactor
In Test-Driven Development (TDD), the typical order of steps for writing and testing code is to first write tests, then write the code to make those tests pass, and finally refactor the code to improve its structure without changing its behavior. This cycle is commonly known as the "Red-Green-Refactor" cycle, emphasizing the iterative nature of TDD and the continuous improvement of code through testing and refactoring.
