While working on some other patches and trying to add
some unit tests there were a few things in os_testr that
made it difficult to test.
Rather than try and be super tricky, just refactor os_testr
a bit.
* Refactor get_parser to handle parse_args for us
We'll need to explicitly pass in argv here
* Move the logic of selecting/calling the test
runner into its own helper method (_select_call_runner)
* Modify existing tests to pass args in to get_parser
* Add a new test for runner selection
This cleans up the logic a bit and makes testing a good
deal easier.
