[Solved] Identify the error in this parameterized test code:import pytest @pytest.mark.parametrize('input, expected') def test_double(input, expected): assert input * 2 == expected @pytest.mark.... | Selenium Python

Selenium Python - Test Framework Integration (pytest)

Identify the error in this parameterized test code:

import pytest

@pytest.mark.parametrize('input, expected')
def test_double(input, expected):
    assert input * 2 == expected

@pytest.mark.parametrize('input, expected', [(2, 4), (3, 6)])

AWrong assertion operator used.

BMissing data list for parameterize decorator on test_double.

CParameters names should be a list, not a string.

DTest function name is invalid.

Step-by-Step Solution

Solution:

Step 1: Check the decorator usage on test_double
The decorator @pytest.mark.parametrize('input, expected') is missing the second argument: the list of data tuples.
Step 2: Verify other parts
Assertion and function name are correct. Parameter names as string is valid syntax.
Final Answer:
Missing data list for parameterize decorator on test_double. -> Option B
Quick Check:
Decorator needs data list argument [OK]

Quick Trick: Always provide data list with parametrize decorator [OK]

Common Mistakes:

Forgetting the data list argument
Using list instead of string for parameter names (which is allowed but less common)
Misreading assertion syntax
