我尝试使用ThreadPoolExecutor以并行模式运行测试，这是我的Runner类

suite = unittest.TestSuite()
    if (options == 'by_method'):
        for object in name:
            for method in dir(object):
                if (method.startswith('test')):
                    suite.addTest(object(method))

    with ThreadPoolExecutor(max_workers=devicesList.__len__()) as executor:
        list_of_suites = list(suite)
        for test in range(len(list_of_suites)):
            test_name = str(list_of_suites[test])
            try:
                executor.submit(unittest.TextTestRunner(verbosity=2).run, list_of_suites[test])
            except:
                pass

这是我的测试课

import unittest
class Runner(unittest.TestCase):
    @classmethod
    def setUpClass(self):
        print("setup method")

    def test_deeplinks(self):
        print("test1")

    def test(self):
        print("test2");

    def test4(self):
        print("test 4")

    def test5(self):
        print("test5");

    @classmethod
    def tearDownClass(self):
        print("tear down ")

if __name__ == '__main__':
    # runner = Runner.Runner()
    # runner.parallel_execution(Runner, TestDeeplinks)
    suite = unittest.TestLoader().loadTestsFromTestCase(Runner)
    unittest.TextTestRunner(verbosity=2).run

但是我的setupClass方法没有被调用有人能告诉我我在这里做什么吗
