How to use the nose2.discover function in nose2

def _run(self):
        argv = ['']
        argv += self.test_args.split()
        collector = Nose2ResultsCollector()

        with open(os.devnull, 'w') as devnull:
            with redirect_stdout(devnull):
                with redirect_stderr(devnull):
                    nose2.discover(argv=argv, extraHooks=[('testOutcome', collector)], exit=False)
        failures = [x for x in collector.events if x.outcome != 'passed']

        return (not failures, [(str(r.test), traceback.format_exception(*r.exc_info)) for r in failures])
