Inconsistent behavior when using tox

[b1quint]

The tests in GitHub Actions are failing while the same tests pass when using Jenkin. You can see the traceback from the latest errors in GitHub Actions here. The traceback itself is a bit obscure.

When calling tox locally, the tests also fail. After trying several options, I realized that they fail when tox is called without any arguments. For example:

$ tox -e py37-unit                                                                                                                                                                                                           

Sometimes the error is the same reported on GitHub Actions, but most of the time the test failures have a different traceback. I am not completely sure that both issues are the same, if they are correlated somehow, or if they are simply two different issues.

The major requirement for our Tox setup is that we can run the tests using the command line above locally. So I will focus on this particular issue. The main error shows as:
