Equivalence Class Testing-Black Box Software Testing Techniques The use of equivalence classes as the basis for functional testing and is appropriate in situations like:   a) When exhaustive testing is desired.   b) When there is a strong need to avoid redundancy. The above are not handled by BVA technique as we can see massive redundancy in the tables of test cases. In this technique, the input and the output domain is divided into a finite number of equivalence classes.   Then, we select one representative of each class and test our program against it. It is assumed by the … Continue reading Equivalence Class Testing-Black Box Software Testing Techniques
