execute tests in CI

[alfredbez]

We have a few unit tests, but we need to execute them in CI. There was already one attempt, but it looks like it is not working at the moment.

@keywan-ghadami-oxid Do you want to take a look into this or should I tackle this?

[alfredbez]

I talked to @keywan-ghadami-oxid and I will take a look at this. We're not sure if we want to make the old unit-tests work or write them from scratch.

We will also remove the UI in the admin area in the next major version, to make it easier to maintain. We recommend using only the oxid-console as an interface to this module.

I have worked on making the old unit tests work:
I managed to get the old tests working in my oxid 6.1 shop with this branch https://github.com/OXIDprojects/oxid_modules_config/tree/fix_tests_for_oxid_6 . Note that the linked branch is based on d01f87a . I have also merged these changes in with the current master branch here: https://github.com/OXIDprojects/oxid_modules_config/tree/make-tests-run-on-oxid-6. Hope this can be of help.
