Here I add a function
import_parallel_h5py
totesting.py
that tries to import a parallel-enabled h5py, and if one isn't available, it raisesunittest.SkipTest
. This replaces most of our uses ofimport_or_skip
(but not all) and callsimport_or_skip
under the hood.Unfortunately, @kwmsmith, it seems to make our paralleltests hang in my testing environment that actually has a parallel build of h5py. It skips tests correctly when there is no h5py or when there is a serial h5py installed.
Not ready for merge.
