Description

Minimal reproducer:

import pytest

@pytest.fixture()
def dynamically_requested_fixture():
    pass

@pytest.fixture()
def dependent_fixture(request):
    request.getfixturevalue('dynamically_requested_fixture')

def test_dyn(dependent_fixture):
    pass

Expected output with --setuponly:

SETUP    F dependent_fixture (fixtures used: dynamically_requested_fixture)

Actual output:

SETUP    F dependent_fixture

Research direction

Start by reproducing the supplied example with pytest's --setuponly and --setupshow options, then trace the code that formats fixture setup output and handles request.getfixturevalue(). Done means both options report dynamically_requested_fixture as a dependency of dependent_fixture, matching the expected output.
