Abstract:
Metamorphic testing is one of the most effective methods
of testing programs with the test oracle problem. This problem declares that
it is impossible to know whether the test answer is correct for one reason or
another. Metamorphic testing uses metamorphic relations to check the program
correctness. Metamorphic relation is a function of several test inputs and
corresponding outputs of the program. Developing metamorphic relations can be
a non-trivial task.
This systematic review is dedicated to identifying general derivation techniques
for metamorphic relation as well as techniques pertinent to particular domains.
As a result, we propose a classification of techniques into six main types and
compile a comparative table of input data transformations for testing tasks
in different domains. Findings of this review will help researchers to apply
metamorphic testing in practice.
Key words and phrases:metamorphic testing, metamorphic relation, software
testing, test oracle problem.
