When multiple parameters are provided, pytest runs the test for each tuple of parameter values supplied.Final Answer:
It runs the test multiple times with each combination of the given parameter values. -> Option AQuick Check:
Multiple parameter sets lead to multiple test runs [OK]
Quick Trick: Parametrize runs tests for each parameter set [OK]
