How to run unit tests on a modified openedx devstack project?

In the past I’ve ran unit test by going to the lms-shell and executing pytest. I am now working on a modified openedx devstack and I get error if I try to execute tests.
There are a lot of settings modules and I do not know which one requires modification.
