Is it expected that the testfiles will be different here then in the tools/testfiles? If not, just copy the files from tools to the correct directories before tests are run. We could even sort the tools/testfiles folder into separate tool folders.

That's the plan at least. This is just initial work on a feature branch towards that so it's easy to compare testfiles and see what's different and the same.

After some discussion, we're going to do some cleanup of the tools test files directories in HDF5 first and then revisit this PR once we've had a chance to clean up a bit beforehand
