'./test <controller> -s spec1 -s spec2' becomes:
'pytest --controller <controller> -k "spec1 or spec2"'
This uses pytest's test selection, which allows finer selection of which tests
to run (for example, it will allow running all tests but those requiring one
feature or combination of features).
It also allows running only a particular test (or set of test) by
filtering on their name or file name.
pytest also shows a much nicer output while testing (grouped by file,
percentage of tests run, manages the verbosity); and it captures all the output
and only shows it if the test fails, which makes --show-io irrelevant.
