There is generally no need to call `undo()`, since it is
called automatically during tear-down.
Note that the same `monkeypatch` fixture is used across a
single test function invocation. If `monkeypatch` is used both by
the test function itself and one of the test fixtures,
calling `undo()` will undo all of the changes made in
both functions.
