What is red/green testing?

Question

I believe I already know the answer, but I am not 100% sure, so just a quick question: What does Red/Green Testing actually mean?

I understand it as \"Write your tests f

Answer 1

When you run a TDD GUI, the display is red until all tests pass, then it switches to green.

This is a summary of the rough outline of test-first development.

1. Write some skeleton code that compiles, has enough API to be testable.

2. Write tests which -- initially -- will be mostly failures. Red.

3. Finish the code. The tests pass. Green.

At this point, you at least have something that works. However, what you have is not very high quality. So you'll need to refactor to improve overall quality.
