Those aren't unit tests, then. A unit test, by definition, tests a small
unit of code; usually one true-or-false assertion about one function

What you describe sounds more like integration tests or feature tests or
acceptance tests; something where large parts of the code base are all
exercised at once.

The ‘testscenarios’ library is one way to have a set of scenarios
applied at run-time to produce tests across all combinations

You may want to look at behaviour-driven testing, e.g. using Behave

Another resource to use is the ‘testing-in-python’ forum
<URL:> where there is
more focussed discussion on testing in Python.
