PyTest - Parametrize

Given this code, what will be the test ID for the third test case?

@pytest.mark.parametrize('val', [5, 0, -1], ids=lambda x: f"val_{x}")
def test_val(val):
    assert val != 0

Atest_val[val_5]

Btest_val[val_0]

Ctest_val[val_1]

Dtest_val[val_-1]

Step-by-Step Solution

Solution:

Step 1: Understand lambda IDs usage
The ids parameter uses a lambda to create IDs like 'val_5', 'val_0', 'val_-1'.
Step 2: Identify third test case ID
The third value is -1, so ID is 'val_-1', making the test ID test_val[val_-1].
Final Answer:
test_val[val_-1] -> Option D
Quick Check:
Lambda IDs create 'val_' + value strings [OK]

Quick Trick: Lambda IDs format test names dynamically [OK]
