I have a class A and B(A) in the following way (ignoring the imports).
# file_1
class A:
def __init__():
...
def some_method():
...
# file_2
class B(A):
def __init__():
super().__init__()
self.some_method()
# test_file
class BTest(unittest.TestCase):
@mock.patch('module.file_1.A.some_method')
def test_something(self, mock_some_method):
b = B()
...
Running the test will call the some_method
real method, not the mocked one. How to mock some_method
before instantiating class B.
