easy📝 Syntax Q3 of 15
Step-by-Step Solution
Solution:
Step 1: Syntax for multiple decorators
Each@pytest.mark.parametrizedecorator takes a parameter name and a list of values.Step 2: Correct usage
Applying two decorators separately formandnis done as in @pytest.mark.parametrize('m', [1, 2]) @pytest.mark.parametrize('n', [3, 4]) def test_func(m, n): pass, but combining parameters in one decorator as in @pytest.mark.parametrize('m, n', [(1, 3), (2, 4)]) def test_func(m, n): pass is also correct and often preferred.Final Answer:
@pytest.mark.parametrize('m, n', [(1, 3), (2, 4)]) def test_func(m, n): pass is the correct syntax for combining parameters in one decorator.Quick Check:
Single decorator with multiple parameters [OK]
Quick Trick: Use single decorator with multiple parameters for combined values [OK]
Common Mistakes:
MISTAKES- Trying to pass multiple parameters in one decorator incorrectly
- Using wrong argument format
