Description

Detects if a by-design crashing black-box script Traceback is visible in the stderr output of orion.

The test succeeds, which indicates that the stacktrace is indeed visible by the user on his terminal output.

Is meant to implement issue #709

Changes

Just a test, since the behaviour is already good.
Added a "black box" utility script that can return a code passed by argument, and/or crash if -c argument is specified.

The test if failing because the script is not found. Pytest is executed from the root so it cannot find this file at the root. You can use monkeypatch to change the working dir temporarily: https://github.com/Epistimio/orion/blob/develop/tests/functional/commands/conftest.py#L61

Note, the first test of this module is not crashing because it has the fixture one_experiment which does this change of working directory.

You could test the exit-code at the same time. The main should return it.
