In a Flask test, you want to mock two different external services called sequentially using requests.get. How can you configure the mock to return different responses for each call?
ASet mock_get.return_value to a single response and change it manually between calls
BCall patch twice on 'requests.get' with different return_value each time
CUse two separate patch decorators for the same function
DSet mock_get.side_effect to a list of mock responses with different return_value attributes
Step-by-Step Solution
Solution:
Step 1: Understand side_effect for sequential calls
side_effect can be set to a list of values or mocks to return different results on each call.
Step 2: Apply side_effect with multiple mock responses
Creating a list of mock responses with different return_value attributes allows each call to requests.get to return a different mocked response.
Final Answer:
Set mock_get.side_effect to a list of mock responses with different return_value attributes -> Option D
Quick Check:
Use side_effect list for multiple call responses [OK]
Quick Trick:Use side_effect list to mock multiple sequential calls [OK]
Common Mistakes:
MISTAKES
Trying multiple patch decorators on same function
Changing return_value manually between calls
Calling patch multiple times incorrectly
