[-]Missing marker in fixturenames for sub-fixture with same name[/-][+]Missing marker in metafunc.fixturenames for sub-fixture with same name[/+]on Jul 25, 2018 I can replicate this with the following test:
def test_extend_fixture_conftest_module_alter_fixtures(self, testdir): testdir.makeconftest(""" import pytest @pytest.fixture def ham(): return 'ham' @pytest.fixture def spam(ham): return ham + 'spam' """) testfile = testdir.makepyfile(""" import pytest @pytest.fixture def spam(spam): return spam * 2 def test_spam(request, spam): assert spam == 'hamspamhamspam' assert 'ham' in request.fixturenames """) result = testdir.runpytest() result.stdout.fnmatch_lines(["*1 passed*"]) result = testdir.runpytest(testfile) result.stdout.fnmatch_lines(["*1 passed*"])
It fails with:
def test_spam(request, spam): assert spam == 'hamspamhamspam' > assert 'ham' in request.fixturenames E AssertionError: assert 'ham' in ['request', 'spam'] E + where ['request', 'spam'] = <FixtureRequest for <Function 'test_spam'>>.fixturenames- changed the title

Having a sub-fixture overwriting a higher-level fixture (with the same name) an argument setup as marker is lost for the higher-level fixture. This is tested with latest pytest 3.6.3.
Here an example:
Workarounds for now are:
I would expect that I can simply overwrite fixtures and markers are still available as arguments for fixtures.
