Final answer:
Partition testing, also known as equivalence partitioning, is a software testing technique used to group test cases into partitions based on input conditions or requirements.
Step-by-step explanation:
Partition testing, also known as equivalence partitioning, is a software testing technique used to group test cases into partitions based on input conditions or requirements. The goal is to cover all possible scenarios within each partition to ensure the software system behaves correctly. For example, if a program accepts values between 1 and 100, partition testing would divide the input range into multiple partitions such as 1-25, 26-50, 51-75, and 76-100, and test representative values from each partition.
