Question

A program is written to compute the total test score, T, from the test scores of the two separate parts, A and B, for an aptitude test as follows: T = A*0.7 + B*0.3 = A*0.5 + B*0.5 if 0 3 AK 25 if 25< A < 50

This program accepts A and B as its input from users. Both A and B fall in the range within 0 to 50 inclusive. That is 0 <= A, B <= 50.

For the program specified above, is it possible for both equivalence class testing technique and cause-effect testing technique to design the same test suite? Explain the reasons clearly. If possible, show the correspondence systematically and concisely.

Answer 1

No, it is not possible for both equivalence class testing and cause-effect testing techniques to design the same test suite.

As we all know that test suit is just a collection of test cases that are intended to be used for testing a software.

Different testing technique performs testing differently.

According to the question,

Equivalence testing technique,

divides the input data of a software into same partitions of equivalent data through which test cases can be derived. These test cases are designed to cover each partition that are created at least once.

while, in cause-effect testing,

it chooses test cases that are logically related to the input that are effecting the output of the software.

So, we can say that these both the testing techniques can't not work on the same test suit.
