Python unit test with base and sub class

Question

I currently have a few unit tests which share a common set of tests. Here\'s an example:

import unittest

class BaseTest(unittest.TestCase):

    def testCo         


        

Answer 1

A way I've thought of solving this is by hiding the test methods if the base class is used. This way the tests aren't skipped, so the test results can be green instead of yellow in many test reporting tools.

Compared to the mixin method, ide's like PyCharm won't complain that unit test methods are missing from the base class.

If a base class inherits from this class, it will need to override the setUpClass and tearDownClass methods.

class BaseTest(unittest.TestCase):
    @classmethod
    def setUpClass(cls):
        cls._test_methods = []
        if cls is BaseTest:
            for name in dir(cls):
                if name.startswith('test') and callable(getattr(cls, name)):
                    cls._test_methods.append((name, getattr(cls, name)))
                    setattr(cls, name, lambda self: None)

    @classmethod
    def tearDownClass(cls):
        if cls is BaseTest:
            for name, method in cls._test_methods:
                setattr(cls, name, method)
            cls._test_methods = []
