Tests should collect without optional dependencies #10246
Description
Currently we silence import issues at test collection (see scientific-python/pytest-doctestplus#108 and xrefs therein) which is the same behaviour as doctest would do when doctest_ignore_import_error is opted in.
Some of the offending modules are also picked up at import tests in #7952
Here is a hopefully full list:
