# TODO: refactor argument parsing to make it possible to feed CLI
# args to plugins via this path (currently done in
# PluggableTestProgram)
# in order to do this, it seems like features in
# PluggableTestProgram need to be factored out into some source
# from which both it and this dummy test case can invoke them
#
# this is the disabled feature:
# ssn.hooks.handleArgs(events.CommandLineArgsEvent(...))
#
# this means that there may be plugins which don't work under
# setuptools invocation because they expect to get handleArgs
# triggered (e.g. older versions of the coverage plugin)
# FIXME: this is all a great-big DRY violation when compared with
# PluggableTestProgram
# create the testsuite, and make sure the createTests event gets
# triggered, as some plugins expect it
# just doing `ldr.loadTestsFromNames` works, but leaves some
# plugins in the lurch
