}What issue are you seeing?
Codex absolutely CANNOT run pytests whatsoever. All pytests report as hanging permanently; Zero output returned. The model seems perplexed by this:
<img width="932" height="75" alt="Image" src="https://github.com/user-attachments/assets/c7bd06a5-c238-40af-a051-66b87194898a" />
i steered it to ask me to run them instead:
"""
I applied the remaining fix work in code and rewrote the affected tests, but verification is blocked by pytest hanging under the required 30s timeout.
Current state:
no background Python/pytest processes are left running
the timed run exited with code 124
redirected output stayed empty before timeout, so I need unbuffered terminal output from you to identify the exact hang/failure point
Please run these two commands separately and paste the full output:
"""
But this is a repeatable issue that happens 100% of the time. Claude code on the other hand, same machine, CLI, latest version, has zero issues with pytest.
Any settings I am missing? Or real bug?
What steps can reproduce the bug?
activate venv (python 3.14.5)
Make project with pytest in it.
Probably need to be using fastAPI and async functions.
Write some tests.
ask codex to run pytest.
hangs.
What is the expected behavior?
Pytest output should be captured successfully.
Additional information
I suspect an issue harness side because agy and claude in the terminal both cleanly capture pytest. Perhaps it's a config issue (hopefully) that I can fix?
