Why is it important to use pytest.raises instead of a try-except block in tests?
Atry-except blocks automatically pass tests on exceptions
Bpytest.raises clearly asserts expected exceptions and integrates with test reports
Cpytest.raises suppresses exceptions without failing tests
Dtry-except blocks are faster and preferred for exception testing

Quick Trick: Use pytest.raises for clear, reliable exception assertions [OK]
