Python unittest.TestCase object has no attribute 'runTest'

Question

For the following code:

import unittest

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

if __name__ == \"__main__\":
    s         


        

Answer 1

You can run it like this:

python -m unittest <your-module-name>

I don't fully understand why it works though.

Answer 2

You need to invoke a TestLoader:

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

Answer 3

You have to specify the test method name (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:

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

Answer 4

The actual test for any TestCase subclass is performed in the runTest() method. Simply change your code to:

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