Fast tests are great, but they don’t guarantee determinism!

C makes sense, but I’m not sure it’s the main point here.

I think B is important too, but not for determinism.

I’m a bit confused, but I remember that speed isn’t really what makes a test deterministic, so I don’t think it’s D.

I feel like I’ve seen a question like this before, and I think it was about consistency, so A sounds right to me.

I’m not entirely sure, but I remember something about testing specific functionality being important. Maybe it’s C?

I think a deterministic test means it gives the same result every time under the same conditions, so I’d go with A.
