A function my_func() returns True when it executes normally. Which Python snippet tests my_func()? A. B. C. D.

The correct answer is A. def test_func(self): self.assertTrue(my_func()). The function returns True, so the test should assert that the return value is True using self.assertTrue(my_func()). Option B uses assertFalse, which would fail because the function returns True. Option C uses assertEqual with a string '{{true}}' which is not a valid boolean…

Explanation

The function returns True, so the test should assert that the return value is True using self.assertTrue(my_func()). Option B uses assertFalse, which would fail because the function returns True. Option C uses assertEqual with a string '{{true}}' which is not a valid boolean comparison. Option D uses assertRaises, which is used to test that an exception is raised, not a return value.
