Neither comments nor lacking unit tests are going to fix that, that's a strawman argument. What I'm saying is if someone doesn't know 100% what their doing, which can be relatively often, then I would hands-down take a bunch of unit tests over some misguided comments because at least the unit tests have to /pass/, so there is some grounding in reality. A comment has absolutely no such requirement and therefore can stray in any direction forever. Also, if you refactor a name of a variable or inputnor function, you will be required to update the tests, so they are dar safer from becoming stale due to refactoring compared to an opaque string from the IDE's point of view.
