Standard test coverage metrics include statement coverage (executing each statement), branch coverage (testing each branch decision), and basic path coverage (covering independent paths). Point to point coverage is not a recognized or standard coverage metric in software testing.
Statement, branch, and basic path coverage are all recognized, well-defined metrics for measuring how much of a program's code has been exercised by tests. 'Point to point coverage' is not a standard test-coverage measure, which is why it's the one that does not belong.
