Rather than outputting the keys, I'd just output a count of passes and fails for a few reasons:
- Keys are limited to ints, or variable names due to using the splat operator rather than accepting an iterable, for example:
->toBeOneOf(thisIsTheOnlyWayToNameAnExpectation: fn($e) => ..., spaces_are_not_allowed: fn($e) => ...) - If you were accepting an iterable rather than using a splat, array keys aren't guaranteed to be unique
- There could be a ton of expectations passed to this function, causing a failure to output a huge error
- Just counting passes and failures reduces the memory overhead
You can also output the total count of assertions ran by checking the delta of Assert::getCount() before and after.
