Answer: Blackbox testing involves testing the functionality of a software ponent without knowing the details of its internal logic. Whitebox testing involves testing the independent logic paths with full implementation knowledge. 8. What is equivalence partitioning as it applies to software testing? What is scenariobased testing? Answer: Equivalence partitioning technique divides the input domain into classes of equivalent data items. Test cases are derived from binations of elem
