python unit test test_function.py fails with MPI
Issue #1130
new
Testing the current Debian build of dolfin, tests continue to pass in single process mode, but many tests from test_function.py in python/test/unit/function/ fail when run with mpi (openmpi):
$ mpirun -n 3 pytest-3 -v test_function.py

Apart from the specific test errors list here, the test run also hangs.
The problem can be seen in debian test logs (non-verbose, reporting only the time-out at test_function.py) and was reported at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1008225
For Debian I’ll work around the problem by skipping test_function.py in the MPI unit tests.

test_function_assigner.py also seems to be affected the same way.
