"""
|
|
Conftest for the harness process-manager / runner tests.
|
|
|
|
Ensures the runner subprocesses these tests spawn can import both
|
|
the production ``omnigent`` package AND the test fixture harness
|
|
at ``tests.runtime.harnesses._test_harness``.
|
|
|
|
pytest's :data:`pyproject.toml` ``pythonpath = ["."]`` adds the
|
|
project root to ``sys.path`` of the test process — but
|
|
:func:`asyncio.create_subprocess_exec` only inherits the OS env
|
|
(``PYTHONPATH``), not the parent's ``sys.path`` mutations. Without
|
|
this fixture the runner subprocess starts with no project root on
|
|
its path and fails to import either ``omnigent.runtime.harnesses._runner``
|
|
or the test harness module.
|
|
|
|
The fixture is autouse-scoped to this directory, so every spawn
|
|
in these tests inherits a PYTHONPATH that includes the project
|
|
root. Setting it via :func:`monkeypatch.setenv` keeps the
|
|
modification scoped to one test — other test modules that don't
|
|
care about PYTHONPATH are unaffected.
