VS Code Python unittest: No tests discovered even when following the tutorial

I am trying to follow the Python tutorial as per https://code.visualstudio.com/docs/python/unit-testing#_create-tests. But every time no tests are discovered and neither I can execute the test file manually: 0 tests are run.

the workspace structure and files content I have tried doing that on my working workspace and then attempted to start everything from scratch but both times the results are the same. Also, I have tried using Remote - WSL on VS Code Insiders and the classic VS Code:

basic.py


    def just_method(number):
        return number

    if __name__ == "__main__":
        print just_method(42)

basictest.py

    import unittest
    import basic

    class MyBasicTests(unittest.TestCase):

        def default_number(self):
            number = 42
            self.assertEqual(basic.just_method(number), number)

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

settings.json content:

    {
        "python.testing.unittestArgs": [
            "-v",
            "-s",
            ".",
            "-p",
            "*test.py"
        ],
        "python.testing.pyTestEnabled": false,
        "python.testing.nosetestsEnabled": false,
        "python.testing.unittestEnabled": true,
        "python.pythonPath": "/usr/bin/python"
    }

Could you please help to identify the problem? I am pretty sure it is located somewhere on my side.

In order to inherit a class, you have to use the super() method.

class ChildClass(ParentClass):
    def __init__(self, *args): # '*args' for arguments to this class
        super().__init__(self, *args) # '*args' for arguments to pass in the parent class's __init__ method

in your case:

# put imports here
class MyBasicTests(unittest.TestCase):
    def __init__(self):
        super().__init__()
    def test_this(self):
        number = 20
        self.assertEqual(number, basic.just_method(number))

File names and method names are important for test discovery. If you follow the tutorial to the letter this should work.

If you want to use your own code instead, try changing default_number to test_default_number, and basictest.py to test_basic.py.
