Implementing the functionality right away seems risky.

I thought you just run it again to confirm the failure first?

Wait, why would you refactor the test? That seems off.

You usually write the minimum code to pass the test.

I recall a similar question where we discussed refactoring tests, but I think that's more about improving code after it passes, not right after a failure.

I feel like we might need to implement the required functionality after a failure, but I'm not completely confident about the order of steps.

I'm not entirely sure, but I remember something about running the test again to confirm it fails before doing anything else.

I think after a test fails, we should write the minimum amount of product code to satisfy the test, right? That sounds like what we practiced.

I remember learning about this in class. After the test fails, the next step is to write the minimum amount of code to satisfy the test. So the answer is definitely B.

I'm not too familiar with test-driven development, so I'm not sure about this one. I might go with D and just implement the required functionality, but I'm not certain that's the best approach.

Okay, I got this. The key is to write the minimum amount of code to pass the test, so the answer has to be B. That's the whole point of test-driven development.

Hmm, I'm a little confused on this one. I think it might be C - run the test again to make sure it really fails. But I'm not totally confident.

I'm going with B. Anything else just feels like you're not following the principles of TDD.
