I am not sure the unit test is needed, as it practically replicates this test in the python-extension-common

We should also change the documentation since we have new parameters in the cli. Plus the usual changelog.

Yes, I used it for the inspiration, but unit test I added is working on a different level - we're checking the functionality of the subclass of the class provided by python-extension-common. As they are now live in separate repos/packages, superclass might change the behaviour without updating the subclass. The test is basic, but I think it is better than nothing

Hm, what new parameter do you mean? I added no new parameters.

Good point about the changelog, will add.

The new parameters are related to SaaS.
