What will be the output when running this parameterized test snippet?

import pytest

@pytest.mark.parametrize('num, expected', [(1, 2), (2, 3), (3, 4)])
def test_increment(num, expected):
    assert num + 1 == expected

ASyntax error due to wrong decorator usage.

BAll tests fail due to assertion errors.

CAll tests pass successfully.

DOnly the first test passes, others fail.

Step-by-Step Solution

Solution:

Step 1: Analyze the test logic and parameters
Each tuple provides num and expected. The test asserts num + 1 == expected. For (1,2), 1+1=2; for (2,3), 2+1=3; for (3,4), 3+1=4.
Step 2: Check if assertions hold for all cases
All assertions are true, so all tests pass.
Final Answer:
All tests pass successfully. -> Option C
Quick Check:
num + 1 equals expected for all [OK]

Quick Trick: Check each input-output pair matches assertion [OK]
