Please come up with some scenario where mocking is required, write the Python class, and the Python unit test that included the patch that enables the mocking. You may patch a single value using return_value, or multiple values with side_effect.

from territory import Territory from army import Army from territory_test import TestDoBattle

t = Territory(10, Army()) t.do_battle(Army()) print(t.curr_territory)

unittest.main()

-----

class Army: def get_curr_strength(self): return 0 # pretend there is code here that returns an actual value

------

from army import Army class Territory: def __init__(self, initial_territory, this_army): self.curr_territory = initial_territory self.this_army = this_army

def do_battle(self, enemy_army): self.curr_territory += self.this_army.get_curr_strength() - \ enemy_army.get_curr_strength() ------

something similar to this code:

from territory import Territory from army import Army import unittest from unittest.mock import patch

class TestThisArmyTenEnemyFiveIncreasesTerritoryByFive(unittest.TestCase): @patch('army.Army.get_curr_strength', side_effect = (10,5)) def runTest(self, _): t = Territory(10, Army()) t.do_battle(Army()) self.assertEqual(15, t.curr_territory)

unittest.main()
