💡 Hint

Common Mistakes

Importing 'mock' instead of 'patch' when the task asks for the decorator.

Trying to import from 'mock' directly instead of 'unittest.mock'.

The patch decorator is imported from unittest.mock to create mocks for external services.

Complete the code to patch the external API call in the test function.

Django

@mock.[1]('myapp.services.external_api_call')
def test_api_call(mock_api):
    pass

💡 Hint

Common Mistakes

Using 'MagicMock' as a decorator instead of 'patch'.

Forgetting to specify the full path to the function to patch.

The @mock.patch decorator replaces the specified function with a mock during the test.

3fill in blank

hard

Fix the error in the mock setup to return a specific value from the external service.

Django

mock_api.[1] = {'status': 'ok'}

Drag options to blanks, or click blank then click option'

Cmock_return

💡 Hint

Common Mistakes

Using 'side_effect' when only a return value is needed.

Trying to assign to 'return' which is a reserved word.

The return_value attribute sets what the mock returns when called.

4fill in blank

hard

Fill both blanks to assert the mock was called exactly once with the expected argument.

Django

mock_api.[1]([2])

Drag options to blanks, or click blank then click option'

Amock_calls

B'test_param'

Cassert_called_once_with

Dcall

Attempts:

💡 Hint

Common Mistakes

Using 'mock_calls' which is a list, not an assertion method.

Passing the wrong argument or forgetting quotes around string arguments.

Use assert_called_once_with to check the mock was called once with the given argument.

5fill in blank

hard

Fill all three blanks to create a mock context manager that returns a mock response with status code 200.

Django

with mock.[1]('myapp.services.get_response') as [2]:
    [3].return_value.status_code = 200

Drag options to blanks, or click blank then click option'

Apatch

Bmock_response

Cmock_obj

Dmock_api

Attempts:

💡 Hint

Common Mistakes

Using the wrong mock variable name inconsistently.

Not setting the return_value on the mock object.

Use patch as a context manager to replace the function. The mock object is assigned to a variable (here mock_obj) to set its return value.
