Python unittest.TestCase object has no attribute 'runTest'
提问by Jingguo Yao
For the following code:
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)
Using Python 3 to execute it, the following error is raised:
使用 Python 3 执行它，出现以下错误：
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'
But unittest.main()works.
但是unittest.main()有效。

You need to invoke a TestLoader:
您需要调用一个TestLoader：
if __name__ == "__main__":
suite = unittest.defaultTestLoader.loadTestsFromTestCase(Test)
unittest.TextTestRunner().run(suite)

The actual test for any TestCasesubclass is performed in the runTest()method. Simply change your code to:
任何子TestCase类的实际测试都在runTest()方法中执行。只需将您的代码更改为：
class Test(unittest.TestCase):
def runTest(self):
assert(True == True)
回答by falsetru
You have to specify the test method name (test1):
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)
Or, if you want to run all tests in the file, Just calling unittest.main()is enough:
或者，如果您想运行文件中的所有测试，只需调用即可unittest.main()：
if __name__ == "__main__":
unittest.main()
