Definitions:

False negative The test reports a failure even though the feature actually works.

False positive The test reports success when it should not.

True positive Correctly identifies something is working.

True negative Correctly identifies something is not working.

In this scenario:

The checkout button does exist, so the feature works.

The test fails incorrectly, because it is checking for the wrong selector.

That is the definition of a false negative.

Definitely False positive. The class mismatch causes the failure.

False negative seems unlikely here. It's about the class.

It's a false positive since the test is looking for something that isn't there.

I thought a false negative was when the test fails to detect something that should be there, so maybe that's the right answer here?

I'm not entirely sure, but I remember a similar question where a test failed because of a missing class. Could it be a true positive?
