Nightly tests
pacxx-ci should run nightly tests.
Currently, nightly tests are run by
- https://zivgitlab.uni-muenster.de/HPC2SE-Project/pacxx
- https://gitlab.dune-project.org/joe/pacxx-docker
However, pacxx does not run the full testsuite, it rather tests the scripts meant for users. And pacxx-docker is using it's own setup rather than this repository, so it can get out of sync.
