MPI-Parallel, Crash-Safe Tests for Pytest

pytest-isolate-mpi is a plugin for Pytest to enable the test of MPI-parallel Python software. MPI-parallel tests are executed in forked MPI jobs with the help of mpirun to isolate the tests from each other. Thus, a crash in test only aborts the test, not the whole test suite. Similarly, deadlocks can be treated with timeouts for tests to prevent a test suite from never being able to finish.
