如何选择在多类Python单元测试中运行哪个测试用例

Question

我在一个模块中有多个测试类ops_tests.py

class TestExecuteProc(unittest.TestCase):
    def test(self):
       <commands>

class TestSetupJobs(unittest.TestCase):
    def test(self):
        <commands>

现在我只想测试第二个类，所以在main中有以下内容

if __name__ == '__main__':

    suite = unittest.TestLoader().loadTestsFromTestCase(TestSetupJobs)
    unittest.TextTestRunner.run(suite)

然而，它仍然运行这两个测试。选择要测试的类的正确方法是什么

您错过了TextTestRunner的实例化：

import unittest

class TestExecuteProc(unittest.TestCase):
    def test(self):
        self.assertTrue(False)

class TestSetupJobs(unittest.TestCase):
    def test(self):
        self.assertTrue(False)

if __name__ == '__main__':

    suite = unittest.TestLoader().loadTestsFromTestCase(TestSetupJobs)
    unittest.TextTestRunner().run(suite)

产出：

F
