From 352478d837893167b90d321e22f276ce65f7ce43 Mon Sep 17 00:00:00 2001 From: Rodolfo Alonso Hernandez Date: Tue, 23 Jan 2018 16:23:57 +0000 Subject: Make 'Scenario' classes plugable This patch makes yardstick.benchmark.scenario.base:Scenario classes plugable. A new entry point is added to the setup. This entry point could be extended in other plugin projects to add new Scenario classes. E.g.: take a look at [1]. This is a Yardstick plugin example project. Clone the project and execute, from the project directory: $ sudo -EH python setup.py install This will add a new module to python ('yardstick-new-plugin') and a new Scenario class. Now list the scenarios in Yardstick: $ yardstick scenario list ... | SpecCPU2006_for_VM | Spec CPU2006 benchmark for Virtual Machine | | SpecCPU2006 | Spec CPU2006 benchmark | | Dummy2 | Execute Dummy (v2!) echo | +-----------------------+--------------------------------------------+ [1] https://github.com/ralonsoh/yardstick_new_plugin JIRA: YARDSTICK-910 Change-Id: Ib70ee9bf4dc7ff91d1dd6377317b313288e36bff Signed-off-by: Rodolfo Alonso Hernandez --- tests/unit/benchmark/scenarios/test_base.py | 53 +++++++++++++++++++++++++++++ 1 file changed, 53 insertions(+) (limited to 'tests/unit/benchmark') diff --git a/tests/unit/benchmark/scenarios/test_base.py b/tests/unit/benchmark/scenarios/test_base.py index 78e342978..a95e6bc86 100644 --- a/tests/unit/benchmark/scenarios/test_base.py +++ b/tests/unit/benchmark/scenarios/test_base.py @@ -51,3 +51,56 @@ class ScenarioTestCase(unittest.TestCase): pass self.assertEqual(str(None), DummyScenario.get_description()) + + def test_get_types(self): + scenario_names = set( + scenario.__scenario_type__ for scenario in + base.Scenario.get_types() if hasattr(scenario, + '__scenario_type__')) + existing_scenario_class_names = { + 'Iperf3', 'CACHEstat', 'SpecCPU2006', 'Dummy', 'NSPerf', 'Parser'} + self.assertTrue(existing_scenario_class_names.issubset(scenario_names)) + + def test_get_cls_existing_scenario(self): + scenario_name = 'NSPerf' + scenario = base.Scenario.get_cls(scenario_name) + self.assertEqual(scenario_name, scenario.__scenario_type__) + + def test_get_cls_non_existing_scenario(self): + wrong_scenario_name = 'Non-existing-scenario' + with self.assertRaises(RuntimeError) as exc: + base.Scenario.get_cls(wrong_scenario_name) + self.assertEqual('No such scenario type %s' % wrong_scenario_name, + str(exc.exception)) + + def test_get_existing_scenario(self): + scenario_name = 'NSPerf' + scenario_module = ('yardstick.benchmark.scenarios.networking.' + 'vnf_generic.NetworkServiceTestCase') + self.assertEqual(scenario_module, base.Scenario.get(scenario_name)) + + def test_get_non_existing_scenario(self): + wrong_scenario_name = 'Non-existing-scenario' + with self.assertRaises(RuntimeError) as exc: + base.Scenario.get(wrong_scenario_name) + self.assertEqual('No such scenario type %s' % wrong_scenario_name, + str(exc.exception)) + + +class IterScenarioClassesTestCase(unittest.TestCase): + + def test_no_scenario_type_defined(self): + some_existing_scenario_class_names = [ + 'Iperf3', 'CACHEstat', 'SpecCPU2006', 'Dummy', 'NSPerf', 'Parser'] + scenario_types = [scenario.__scenario_type__ for scenario + in base._iter_scenario_classes()] + for class_name in some_existing_scenario_class_names: + self.assertIn(class_name, scenario_types) + + def test_scenario_type_defined(self): + some_existing_scenario_class_names = [ + 'Iperf3', 'CACHEstat', 'SpecCPU2006', 'Dummy', 'NSPerf', 'Parser'] + for class_name in some_existing_scenario_class_names: + scenario_class = next(base._iter_scenario_classes( + scenario_type=class_name)) + self.assertEqual(class_name, scenario_class.__scenario_type__) -- cgit 1.2.3-korg
