[Solved] Identify the error in this pytest code using multiple parameters:import pytest @pytest.mark.parametrize('a, b', [1, 2, 3]) def test_multiply(a, b): assert a * b > 0 | PyTest

PyTest - Parametrize

Identify the error in this pytest code using multiple parameters:

import pytest

@pytest.mark.parametrize('a, b', [1, 2, 3])
def test_multiply(a, b):
    assert a * b > 0

AThe test function must return a value

BThe parameter names should be a list, not a string

CThe assertion syntax is incorrect

DThe parameter values should be tuples, not integers

Step-by-Step Solution

Solution:

Step 1: Check the parameter values format
Values must be a list of tuples matching parameters (a, b), but here it's a list of integers.
Step 2: Understand why this causes error
Pytest tries to unpack each integer into two variables, causing a TypeError.
Final Answer:
The parameter values should be tuples, not integers -> Option D
Quick Check:
Values must match parameter count [OK]

Quick Trick: Use tuples for multiple parameters values [OK]
