PyTest - Parametrize

What is wrong with this pytest parametrize usage?

@pytest.mark.parametrize('x,y', [(1, 2), (3, 4)], ids=['first'])
def test_add(x, y):
    assert x + y > 0

AThe parameter names should be a dictionary, not a string

BThe length of the ids list does not match the number of parameter sets

Cids should be a string, not a list

DThe test function must have only one argument when using ids

Step-by-Step Solution

Solution:

Step 1: Check ids length
There are two parameter sets but only one ID provided.
Step 2: Understand requirement
The ids list length must match the number of parameter tuples.
Final Answer:
The length of the ids list does not match the number of parameter sets -> Option B
Quick Check:
ids length must equal parameter sets count [OK]

Quick Trick: Match ids count to parameter tuples [OK]
