In contrast to model checking, testing works with a subset of program traces instead of every possible trace. Test cases may pass when a property is checked in all, some or none of the given traces. Thus we extend ⊨ for sets of traces and the ∀ and ∃ quantifier operators. ...
One of the worst things is you aren't allowed to implement some operators that the library implements so it is almost impossible to write drop in replacements and you are forced to refactor hundreds to thousands of lines of code. This just makes the entire language difficult to use at scale...
