用于单元测试的python3：AttributeError：模块'__main__'没有属性“内核......”

Question

I am practicing the unittest for python and it always directed to a JSON file:

#unittest code# import unittest from name_function import get_formatted_name class NamesTestCase(unittest.TestCase):

    def test_first_last_name(self):
        formatted_name=get_formatted_name("allen","park")
        self.assertEqual(formatted_name,"Allen Park")

unittest.main()

ERROR: /Users/xxx/Library/Jupyter/runtime/kernel-0eacd257-bf93-4c0f-843c-2e8a96377a17 (unittest.loader._FailedTest)

AttributeError: module ' main ' has no attribute '/Users/xxx/Library/Jupyter/runtime/kernel-0eacd257-bf93-4c0f-843c-2e8a96377a17'

the traceback is：

 SystemExit Traceback (most recent call last) <ipython-input-1-15fe4fc5728d> in <module>() 20 self.assertIn(response,my_survey.responses) 21 ---> 22 unittest.main() /anaconda3/lib/python3.6/unittest/main.py in __init__(self, module, defaultTest, argv, testRunner, testLoader, exit, verbosity, failfast, catchbreak, buffer, warnings, tb_locals) 93 self.progName = os.path.basename(argv[0]) 94 self.parseArgs(argv) ---> 95 self.runTests() 96 97 def usageExit(self, msg=None): /anaconda3/lib/python3.6/unittest/main.py in runTests(self) 256 self.result = testRunner.run(self.test) 257 if self.exit: --> 258 sys.exit(not self.result.wasSuccessful()) 259 260 main = TestProgram SystemExit: True

How do I fix this?

Answer 1

Have a look at " https://medium.com/@vladbezden/using-python-unittest-in-ipython-or-jupyter-732448724e31 "

if __name__ == '__main__':
    unittest.main(argv=['first-arg-is-ignored'], exit=False)

Answer 2

using following:

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

It worked, but was failing before due to a mirror typo. I replaced:

self.asertEqual

with:

self.assertEqual
