Ansible lookup not found starting with pytest-ansible version 24.1.4

[andy-maier]

I am developing an Ansible lookup, and test that using pytest and pytest-ansible.

The pytest test function looks like this (simplified):

import pytest

@pytest.mark.ansible(host_pattern='localhost', connection='local')
def test_mylookup(ansible_module):
    expr = "lookup('myorg.mycoll.mylookup', 'someterm')"
    contacted = ansible_module.set_fact(result=f"{{{{ {expr} }}}}")
    contacted_host = contacted['localhost']
    assert 'failed' not in contacted_host
    result = contacted_host['ansible_facts']['result']
    # assertions on result

Up to pytest-ansible version 24.1.3, this worked fine.

Starting with pytest-ansible version 24.1.4, this fails because the lookup plugin is no longer found, and I get:

contacted_host={
    'failed': True,
    'msg': 'lookup plugin (ibm.zvpc.image_filename) not found',
    '_ansible_no_log': False
}

The lookup plugin is installed and available for Ansible. ansible-galaxy collection list shows the collection with the lookup plugin as installed in /Users/maiera/.ansible/collections/ansible_collections and I did verify that up to version 24.1.3, the code in that install directory gets control during the test. I have no ANSIBLE env vars set, and no ansible.cfg file. ansible-config dump reports:

COLLECTIONS_PATHS(default) = ['/Users/maiera/.ansible/collections', '/usr/share/ansible/collections']

So my collection is found by Ansible using this default configuration.

Pytest command line:

pytest --cov=myproject --cov-config .coveragerc --cov-append --cov-report=term-missing  -s --ansible-host-pattern localhost test

Why is the lookup no longer found starting with pytest-ansible version 24.1.4?
Is this something I can fix, or does this require a fix by pytest-ansible?

As a workaround, I am pinning pytest-ansible<=24.1.4 at the moment, to have my tests working.
