Overriding host fixture causes an AttributeError: 'SubRequest' object has no attribute 'param'

[CarstenGrohmann]

Hi,

I tried to replace the host fixture with an own implementation to skip test modules based on Ansible groups. I simply created a new host fixture in tests/conftest.py.

$  cat hosts
[local]
localhost

[skip_test_mytest_file]
mytesttarget

$ cat tests/conftest.py
import pytest

@pytest.fixture(scope='module')
def host(host, request):
    for groupname in host.ansible.get_variables()["group_names"]:
        if groupname.startswith("skip_%s" % request.module.__name__):
            pytest.skip()
    return host

But unfortunately the code fails with:

request = <SubRequest '_testinfra_host' for <Function test_mytest>>

    @pytest.fixture(scope="module")
    def _testinfra_host(request):
>       return request.param
E       AttributeError: 'SubRequest' object has no attribute 'param'

../../virtualenv/lib64/python3.10/site-packages/testinfra/plugin.py:28: AttributeError

It looks like the optional param attribute is missing and this triggers the issue.

pytest-testinfra/testinfra/plugin.py

Lines 26 to 33 in f921bb8

	@pytest.fixture(scope="module")
	def _testinfra_host(request):
	return request.param
	@pytest.fixture(scope="module")
	def host(_testinfra_host):
	return _testinfra_host

The current workaround is to name the new fixture ansiblehost and use it in my code. However, this leads to a lot of code changes.

Please provide a possibility to replace the host fixture with an own implementation.

Thank you,
Carsten
