Running tests that use CourseFactory.create()

Hello!

Sorry for the ignorance, I am new to the project and trying to contribute where I can.
I am looking if I can contribute to this issue.
But I am having problems running the tests (without any changes)

Using devstack.

make dev.up.large-and-slow
make cms-shell
pytest cms/djangoapps/contentstore/management/commands/tests/test_export_olx.py

This gives me a failed test (1 failed, 3 passed, 1 skipped, 11 warnings in 4.28s):

Basically, any test that I run that uses CourseFactory.create() gives me AttributeError: type object 'HiddenBlockWithMixins' has no attribute 'enrollment_start' in the same place.
I don’t know if I am missing anything.

When an XBlock cannot be loaded normally, it sometimes gets replaced with HiddenBlock. So the root issue is probably that one or more of the XBlocks used by CourseFactory is not installed properly into your python virtual environment. In this case, it can’t find the course XBlock, which is kind of an important one.

You may be able to fix it simply by running pip install -e . in your edx-platform folder. This will scan setup.py for all the XBlocks, including course. Then try again.

That was it. Thanks!
