pytest-doctestplus fails with editable install #7784
Description
I've been a bit annoyed for some time now that I can't test doctests locally because I'm using an editable install. And since that is also the workflow we recommend in our docs I tried to address it.
Installing skimage in editable mode
spin install --editable
will create some differences between which doctests are expected to exist and which are available at runtime. E.g. consider brief_pythran.py. That one will be found in the source by
spin test -- --doctest-plus skimage
but there will be no corresponding module brief_pythran at runtime because that get's transpiled to
scikit-image/skimage/feature/meson.build
Line 26 in 17af81b
There are currently 8 such cases:

For a start I tried ignoring these tests. __doctest_skip__, and different pytest hooks in our conftest.py all didn't work so far.
I'm not yet sure how to proceed. But at least I can document my troubles. 😅
