PyTest - Parametrize

What will be the output of the following test run count?

@pytest.mark.parametrize('x', [0, 1])
@pytest.mark.parametrize('y', [True, False])
@pytest.mark.parametrize('z', ['a', 'b'])
def test_example(x, y, z):
    assert True

A8

B6

C4

D2

Step-by-Step Solution

Solution:

Step 1: Count values in each parametrize decorator
x has 2 values, y has 2 values, z has 2 values.
Step 2: Calculate total test cases
Total tests = 2 * 2 * 2 = 8.
Final Answer:
pytest runs 8 tests for all parameter combinations. -> Option A
Quick Check:
Multiply all parameter counts for total tests [OK]

Quick Trick: Multiply all parameter counts for total tests [OK]

Common Mistakes:

MISTAKES

Forgetting one decorator's parameters
Adding counts instead of multiplying
Assuming only two decorators count
