We currently use Phpstan Release 1. Release 2 has been available for some time, and we would like to stay current if possible. In order to get to Release 2, we first have to pass the "bleeding edge" tests for Release 1. I will do this by generating a new baseline using bleeding edge, then fix the baseline errors over several different PR's. This is the first of those.
While we might never be able to have 100% of our code strict, we can at
the very least do it for all of our tests. This ensures that our tests
are using our API with the types as intended by the test author, and not
silently be cast to what our API requires.
