What is wrong with this test code that tries to mock an external API call?

from unittest.mock import patch

def test_api_call():
    with patch('myapp.services.external_api_call') as mock_call:
        mock_call.return_value = {'success': True}
    result = external_api_call()
    print(result)

Aexternal_api_call cannot be patched with patch()

BThe patch context ends before calling external_api_call

Cmock_call.return_value should be set after calling external_api_call

DMissing import for external_api_call

Step-by-Step Solution

Solution:

Step 1: Check patch context usage
The patch is applied only inside the with block, but external_api_call is called after it ends.
Step 2: Understand effect on mocking
Since external_api_call is called outside the patch block, it is not mocked and runs the real function.
Final Answer:
The patch context ends before calling external_api_call -> Option B
Quick Check:
Call must be inside patch block = C [OK]

Quick Trick: Call mocked function inside patch block or decorator [OK]

Common Mistakes:

MISTAKES

Calling function outside patch context
Setting return_value too late
Assuming patch works globally without context
