The style tests are currently way too complicated for what they do.
We should clean up the tests, a first step is to pass all the tests in the same formats. We have our own 'testall' that runs bash and python tests
that do not requires any test framework overlay.

I will translate all the tests located in the 30_generic_methods in python using unittest since some tests already use it.
This way, it should be easier to understand what each test does since they will follow a documented and standard format, callable in a single line.
