PyTest - Parametrize
What happens when you use multiple @pytest.mark.parametrize decorators on a single test function?
AThe test runs with all combinations of the parameters from each decorator.
BOnly the parameters from the first decorator are used.
CThe test runs once with the parameters from the last decorator only.
DIt causes a syntax error and the test does not run.
Step-by-Step Solution
Solution:

  1. Step 1: Understand multiple parametrize decorators

    Each @pytest.mark.parametrize decorator adds a set of parameters to the test function.

  2. Step 2: Combine parameters from all decorators

    pytest runs the test for every combination of parameters from all decorators, creating a Cartesian product.

  3. Final Answer:

    The test runs with all combinations of the parameters from each decorator. -> Option A

  4. Quick Check:

    Multiple parametrize = all combinations [OK]
Quick Trick: Multiple parametrize means all parameter combos run [OK]
Common Mistakes:
MISTAKES
  • Thinking only the first or last decorator applies
  • Assuming decorators overwrite each other
  • Believing it causes syntax errors
