Final answer:
Equivalence class testing for Max.java involves creating test cases where each case represents a partition of input data. Test Case 1 with input [1, 2, 3] and Test Case 2 with input [1, 1, 1] both are from the positive number equivalence class, ensuring the program can identify the maximum value correctly.
Step-by-step explanation:
When testing a Java program like Max.java, which presumably finds the maximum value among its inputs, equivalence class testing is a method where you divide the input data of a software unit into partitions of equivalent data from which test cases can be derived. For an application that calculates the maximum, one can consider both positive and negative numbers as two different equivalence classes. Here are two test case examples:
Both test cases belong to the same equivalence class of positive numbers. Each test case represents a scenario—the first where numbers are strictly increasing, and the second where all numbers are equal. Both are valid cases that help ensure the Max.java program correctly identifies the maximum number from a list of positive integers.Equivalence class partitioning is a testing technique that involves dividing a set of test cases into groups or classes based on similar characteristics. In the case of testing the Java Max.java program, we can create two test cases that belong to the same equivalence class by selecting two numbers from the range of valid inputs.
