Which of the following is the minimum set of test conditions to achieve 100% coverage with the equivalence partitioning test technique?

You are testing a native application for a smart phone. The application allows the user to make grocery lists on the phone and store up to three lists at a time. A list can contain up to 50 items.

Which of the following is the minimum set of test conditions to achieve 100% coverage with the equivalence partitioning test technique?
A . List with 47 items
B . List with 0 items, List with 1 item, List with 50 items, List with 51 items, 0 lists saved, 1 list saved, 3 lists saved, 4 lists saved
C . List with 0 items, List with 25 items, List with 51 items, 3 lists saved

Answer: D

Explanation:

D is correct as it tests each condition with invalid too low, valid and invalid too high values.

A is incorrect because it doesn’t consider the list save capabilities and it doesn’t test the invalid values for the list.

B is incorrect because it is doing BVA which results in too many tests for minimum coverage with EP.

C is incorrect because it does not sufficiently test the save feature.
