Run TestSafeOrNot:test_cant_do_something_forbidden in Tutor

[kdmccormick]

Background

In #155 we cataloged whether each edx-platform test fails, passes, or is skipped in both Devstack and Tutor Nightly (using edx-platform master, in Jan 2023).

This one test passes in Devstack but is skipped in Tutor: edx-platform:xmodule/capa/safe_exec/tests/test_safe_exec.py::TestSafeOrNot::test_cant_do_something_forbidden

Tasks

Fix the test or Tutor so that running:

tutor dev run lms bash
  lms> unset DJANGO_SETTINGS_MODULE
  lms> unset SERVICE_VARIANT
  lms> export EDXAPP_TEST_MONGO_HOST=mongodb
  lms> pytest 'xmodule/capa/safe_exec/tests/test_safe_exec.py::TestSafeOrNot::test_cant_do_something_forbidden'

in Tutor Nightly passes.

(test running instructions came from here: https://docs.tutor.overhang.io/dev.html#running-edx-platform-unit-tests)

Notes

safe_exec calls out to Codejail. So, this is likely the result of some Codejail configuration, or related environment setup, that Devstack has but Tutor does not.

The test can ran in Devstack with:

make lms-shell
  lms> pytest 'xmodule/capa/safe_exec/tests/test_safe_exec.py::TestSafeOrNot::test_cant_do_something_forbidden'

@kdmccormick I am working on this issue and here is what i have found
From the security issue mentioned here overhangio/tutor#443 we see that the python interpreter is explicitly disabled.
How do we want to go about this now?

@solababs Looking into this issue I see that you can use the plugin tutor-contrib-codejail plugin to enable codejail.

Does enabling that plugin allow the test to run? Does it pass? If so, I personally feel this issue can be closed since the test can pass on tutor.

@xitij2000 Thanks for your help on this. I have been able to adequately implement tutor-contrib-codejail and the the test passed on tutor.
Please let me know what to do with this ticket.

Can you create a PR againt edx-platform that changes the condition in which the test is considered skipped? The test should run if tutor is configured with the codejail service.
