End-to-end testing with PHP backend and JS Frontend

[rugk]

The problem

We have no e2e tests yet in our project, but in an aftermath of a release, we think we should probably add something. These tests should just automatically spin up a browser and test the most common usage scenarios making sure everything works in combination.

The solution

• it must work offline (possibly in a container or whatever)
• and be fully automated
• must run automatically in GitHub Actions
• for a start should cover the most common scenarios [which?], later more could be added

Ideas would be:

• cypress?

Alternatives

• manual testing before a release like currently suggested in the release checklist

Additional context
