Multiple choice technology testing

What is an equivalence partition (also known as an equivalence class)?

  1. A set of test cases for testing classes of objects

  2. An input or output range of values such that only one value in the range becomes a test case

  3. An input or output range of values such that each value in the range becomes a test case

  4. An input or output range of values such that every tenth value in the range becomes a test case.

B Correct answer
Explanation

Equivalence partitioning divides input or output data into ranges where the system handles all members similarly. Therefore, testing just one representative value (597078) suffices to cover the partition. Testing every value (597080) is redundant and defeats the purpose of the technique, while options 597078 and 597081 do not define equivalence classes.
