PyTest - Parametrize
How can you combine multiple @pytest.mark.parametrize decorators with a fixture that provides a third parameter c to test all combinations of a, b, and c?
AUse multiple parametrize decorators for 'a' and 'b', and add 'c' as a fixture argument in the test function.
BAdd 'c' to one of the parametrize decorators as a parameter list.
CUse a single parametrize decorator for all three parameters including 'c'.
DFixtures cannot be combined with parametrize decorators.
Step-by-Step Solution
Solution:
Step 1: Use parametrize decorators for 'a' and 'b'
Define separate decorators for these parameters.
Step 2: Add fixture 'c' as argument to test function
pytest injects fixture value automatically.
Final Answer:
Use multiple parametrize decorators for 'a' and 'b', and add 'c' as a fixture argument in the test function. -> Option A
Quick Check:
Fixtures and parametrize combine via function arguments [OK]
Quick Trick:Add fixture as argument; parametrize decorators handle other params [OK]
Common Mistakes:
MISTAKES
Trying to parametrize fixture values
Combining fixture with parametrize in one decorator
Believing fixtures can't be used with parametrize
