Fix ZeroDivisionError
in pytest
✅ Solution
A ZeroDivisionError in pytest usually arises from dividing by zero during a test, often within custom test logic or fixtures. To fix it, carefully inspect the traceback to pinpoint the faulty calculation and ensure the denominator is never zero by adding conditional checks or using appropriate error handling techniques to prevent the division. Provide a default value or use `pytest.skip` if a zero denominator renders the test meaningless.
