Once the files were cached, the function was still trying to open the
paths passed into it, not the cached paths. This fixes that and adds
additional unit tests.
This change does 2 things:
- Skip 2 tests: they are not actually _testing_ anything, just running functions
Let's skip these for now until we can dedicate some time to investigate what
should be tested here. This will also help the tests breath a little bit.
- Add a small sleep to the async test. This test needs a little breathing room so
the procs don't get stepped on. I think this is what is causing the master to
shut down sometimes during test runs:
