Hydrogen: Running unit tests in Python kernel

[homocomputeris]

Hi,

Is it possible to run Python's unittest.main() in Hydrogen? I haven't found any info, so I don't know if it is a bug or a limitation.

The test runs in the IPython shell.

ERROR: /run/user/1000/jupyter/kernel-9871a573-6183-41d6-b478-ee33edba7173 (unittest.loader._FailedTest)

Do the tests work inside the jupyter notebook?

Well, it doesn't work in Jupyter when using

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

but works with something like

test_suite = unittest.TestSuite()
test_suite.addTest(unittest.makeSuite(TestStringMethods))
runner=unittest.TextTestRunner()
runner.run(test_suite)

So, not a Hydrogen problem, I believe.

This version of the .main call:

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

works fine for me. (Source.)

Closing since a solution seems to have been found! :tada:
