easy📝 Syntax Q3 of 15
Step-by-Step Solution
Solution:
Step 1: Recall correct parametrize syntax for one parameter
The parameter name must be a string, and the values must be a list or tuple.Step 2: Evaluate each option
@pytest.mark.parametrize('num', [1, 2, 3]) correctly uses a string and a list. @pytest.mark.parametrize(num, [1, 2, 3]) misses quotes around the parameter name. @pytest.mark.parametrize(['num'], (1, 2, 3)) uses a list for names but tuple for values incorrectly. @pytest.mark.parametrize('num', 1, 2, 3) passes multiple arguments instead of a list.Final Answer:
@pytest.mark.parametrize('num', [1, 2, 3]) -> Option AQuick Check:
Parametrize single param = string + list [OK]
Quick Trick: Always quote parameter names as strings [OK]
Common Mistakes:
MISTAKES- Not quoting parameter names
- Passing multiple values without list or tuple
- Using wrong data types for values
