Is it a positive to have pathogens that cause dengue/malaria in your blood? Yet we still say that someone tested positive for dengue if they have the virus.
Static analysis tools don't test for all known issues either, no?
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.
