Correct.

Beats me; I see no reason why you couldn't, though.

Probably test_bool(), I guess: self.test_bool('self.run.is_draft()')
asserts that self.run.is_draft() will return true.  Or does
self.assert_() do something more?

These 3 questions are all related, really.  At the bottom of our test
scripts, we have the following stereotyped code:

if __name__ == "__main__":
    (scenarios, options) = parse_args()
    run_scenarios (scenarios, options)

parse_args() ensures consistent arguments to test scripts; -c measures
code coverage, -v is verbose, etc.  It also looks in the __main__
module and finds all subclasses of TestScenario, so you can do:  

python test_process_run.py  # Runs all N scenarios
python test_process_run.py ProcessRunTest # Runs all cases for 1 scenario
python test_process_run.py ProcessRunTest:check_access # Runs one test case
                                                       # in one scenario class
