Selenium Python - Data-Driven Testing

Consider this pytest test using data providers:

import pytest

@pytest.mark.parametrize('input,expected', [(2,4), (3,9)])
def test_square(input, expected):
    assert input ** 2 == expected

What happens if you add a third tuple (4, 15) to the list?

AThe third test fails because 4 squared is 16, not 15

BAll tests pass because 15 is close to 16

CSyntax error due to extra tuple

DTest runner skips the third tuple silently

Step-by-Step Solution

Solution:

Step 1: Understand the test logic
Test checks if input squared equals expected value.
Step 2: Evaluate third tuple
4 squared is 16, but expected is 15, so assertion fails.
Final Answer:
The third test fails because 4 squared is 16, not 15 -> Option A
Quick Check:
Incorrect expected value causes test failure [OK]

Quick Trick: Check expected values carefully; wrong expected causes failure [OK]
