PyTest - Parametrize

What will be the output when running this pytest test?

import pytest

@pytest.mark.parametrize('x, y', [(1, 2), (3, 4)])
def test_sum(x, y):
    assert x + y == 3

AFirst test passes, second test fails

BBoth tests fail

CBoth tests pass

DFirst test fails, second test passes

Step-by-Step Solution

Solution:

Step 1: Evaluate first test with inputs (1, 2)
Sum is 1 + 2 = 3, assertion 3 == 3 passes.
Step 2: Evaluate second test with inputs (3, 4)
Sum is 3 + 4 = 7, assertion 7 == 3 fails.
Final Answer:
First test passes, second test fails -> Option A
Quick Check:
Check sums against 3 [OK]

Quick Trick: Calculate sums for each tuple and compare [OK]
