It is OK to skip tests locally due to missing of imports, but not on github. In this way we may risk to remove dependencies and thus stop testing parts of the code without it being picked up on in the CI/CD workflows.

If this is to be accepted, we need to have an additional check after ctest, that check that all skipped tests are in the specified list of tests (e.g. mongodb-test cannot run on github)

It can be implemented with importskip() checking an environment variable. If it is set, the skip will not be accepted.
