@risicle, all your suggested changes have been included now.

Hmm. The tests seem to be taking a lot longer than they were previously for me. I wonder if it would be better to blacklist a few of the worst offenders by adding them to the rm list.

I filed an issue with the Sfepy developer regarding having a --fast option for the tests, but in the meantime I removed the slowest ones so we can move forward with this. The tests run in ~20s now for me.

Cool. For some reason test_splinebox.py fails for me now under py27/macos 10.13. Investigating, because it's fine on linux and also on py37...

Ok, the problem seems to be a fairly standard matplotlib/macos one that can be solved with a modification to the checkPhase:

   checkPhase = ''
     export HOME=$TMPDIR
     mv sfepy sfepy.hidden
     mkdir -p $HOME/.matplotlib
     echo "backend: ps" > $HOME/.matplotlib/matplotlibrc
     ${python.interpreter} run_tests.py -o $TMPDIR/test_outputs --raise
   '';

I've added the -o option and kept --raise to help the next person who breaks these tests - otherwise the exact reason for failure requires a bit of digging.

@riscle, ping reminder that I made necessary changes.
