Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
mock.check_called(None)
Why it's wrong here
This method does not exist.
- ✗
assert not mock.called
Why it's wrong here
While this works, it is not an 'assert_...' method call on the mock.
- ✗
mock.called == False
Why it's wrong here
Requires assertion, just checking the property is not an assertion call.
- ✓
mock.assert_not_called()
Why this is correct
Explicit method for this purpose.
- ✓
mock.assert_called_count(0)
Why this is correct
Valid numerical check.
