Python unittest.TestCase对象没有属性'runTest'

Question

对于以下代码：

import unittest

class Test(unittest.TestCase):
    def test1(self):
        assert(True == True)

if __name__ == "__main__":
    suite = unittest.TestSuite()
    suite.addTest(Test())
    unittest.TextTestRunner().run(suite)

使用Python 3执行它，会引发以下错误：

Traceback (most recent call last):
  File "test.py", line 10, in <module>
    unittest.TextTestRunner().run(suite)
  File "/usr/lib/python3.2/unittest/runner.py", line 168, in run
    test(result)
  File "/usr/lib/python3.2/unittest/suite.py", line 67, in __call__
    return self.run(*args, **kwds)
  File "/usr/lib/python3.2/unittest/suite.py", line 105, in run
    test(result)
  File "/usr/lib/python3.2/unittest/case.py", line 477, in __call__
    return self.run(*args, **kwds)
  File "/usr/lib/python3.2/unittest/case.py", line 408, in run
    testMethod = getattr(self, self._testMethodName)
AttributeError: 'Test' object has no attribute 'runTest'

但unittest.main()工作。

Answer 1

你需要调用TestLoader：

if __name__ == "__main__":
    suite = unittest.defaultTestLoader.loadTestsFromTestCase(Test)
    unittest.TextTestRunner().run(suite)

Answer 2

您必须指定测试方法名称（test1）：

import unittest

class Test(unittest.TestCase):
    def test1(self):
        assert(True == True)

if __name__ == "__main__":
    suite = unittest.TestSuite()
    suite.addTest(Test('test1')) # <----------------
    unittest.TextTestRunner().run(suite)

或者，如果您想在文件中运行所有测试，只需调用unittest.main()即可：

if __name__ == "__main__":
    unittest.main()

Answer 3

任何TestCase子类的实际测试都是在runTest()方法中进行的。只需将您的代码更改为：

class Test(unittest.TestCase):
    def runTest(self):
        assert(True == True)
