Research on Metamorphic Testing: A Case Study in Integer Bugs Detection

摘要

In order to solve Test Oracle problem which restricts the development of software testing techniques significantly, Metamorphic Testing is used to prove a way to determine the correctness of testing outputs with metamorphic relations between a series of outputs that correspond to a series of inputs in integer bugs detection, based on necessary properties of software under testing. A metamorphic relationship is proposed which can detect invisible integer bugs without oracle. It is shown in our case study that this method can detect some invisible errors which are difficult to be found in conventional approach and improve the efficiency of integer bugs detection.
