"""Tests that parameterized fixtures effect subsequent fixtures. (#6436)
If a fixture uses a parameterized fixture, or, for any other reason, is executed
after the parameterized fixture in the fixture stack, then it should be affected
by the parameterization, and as a result, should be torn down before the
parameterized fixture, every time the parameterized fixture is torn down. This
should be the case even if autouse is involved and/or the linear order of
fixture execution isn't deterministic. In other words, before any fixture can be
torn down, every fixture that was executed after it must also be torn down.
