How to patch a module method that is called within a class?-CodePudding

I have the following structure:

# create.py
import sshHandler
class Create:
    def __init__(self):
        self.value = sshHandler.some_method()

# sshHandler.py
def some_method():
    return True

If I kow try to patch sshHandler.some_method it will not work as expected

from unittest import TestCase
from unittest.mock import patch
import create
class TestCreate(TestCase):
    @patch("sshHandler.some_method")
    def test_create(self, mock_ssh):
        mock_ssh.return_value = False
        c = create.Create()
        # c.value = True but should be false

The result I am looking for is that some_method would be patched in create as well (and return false). If I just call some_method in the context of test_create it works as expected. How do I fix the patch so that it is also active in the Create class when accessing sshHandler?

I saw this question Why python mock patch doesn't work?, but couldn't solve my problem with the information given there.

CodePudding user response：

You've patched the wrong module. Instead patch the sshHandler.some_method patch create.sshHandler.some_method. You must patch the object of module you're handling.
