How to request a fixture in another fixture, without passing it as a parameter

[alexander-soare]

I'm aware of pytest.mark.usefixtures, and I find it useful for the very reasons stated in the documentation: if your test does not use the return value of the fixture, but depends on some global effects it produces, then it's not sensible to have it as a dummy argument, even if you wish to request it.

How do I solve the same problem if I need my fixture to request another fixture, but it's not sensible to pass the requested fixture is a parameter?
