Python unittest.TestCase 对象没有属性“runTest" [英] Python unittest.TestCase object has no attribute 'runTest'

问题描述

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，出现如下错误:

Using Python 3 to execute it, the following error is raised:

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'

但是 unittest.main() 有效.

推荐答案

你需要调用一个 TestLoader:

You need to invoke a TestLoader:

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