I’m not debating. It is not a matter of opinion. I’m doing you the courtesy of informing you how the entire rest of the world uses the term.

If action A looks for thing X, and it finds thing X, then the test is positive. If action A fails to find thing X, then the test is negative.

If action A claims to find thing X, but later confirmation determines that thing X is not really there, then this situation is called “false positive”.

If action A claims fails to find thing X, but later confirmation determines that thing X is actually there, then this situation is called “false negative”.

That thing X may subjectively be considered an unwanted outcome has **nothing ** to do with the terms used.

You could say “A static analysis tool is testing for the for the presence of defects” or “a medical test is testing if your body is free of diseases that it can detect” to change how you’re looking at either of the tests in the previous comment.
