PyTest - Parametrize

Which of the following is the correct way to parametrize a test function with two parameters x and y in pytest?

A@pytest.mark.parametrize(('x', 'y'), [(1, 2), (3, 4))

B@pytest.mark.parametrize('x, y', [(1, 2), (3, 4)])

C@pytest.mark.parametrize(['x', 'y'], [(1, 2), (3, 4))

D@pytest.mark.parametrize('x y', [(1, 2), (3, 4)])

Step-by-Step Solution

Step 1: Recall pytest parametrize syntax
The parameter names are passed as a single string separated by commas.
Step 2: Check each option
@pytest.mark.parametrize('x, y', [(1, 2), (3, 4)]) correctly uses a string with comma-separated parameter names and a list of tuples for values.
Final Answer:
@pytest.mark.parametrize('x, y', [(1, 2), (3, 4)]) -> Option B
Quick Check:
Param names as string with commas = correct syntax [OK]

Quick Trick: Use string with commas for multiple params [OK]
