In software testing, an oracle refers to a mechanism against which testers can decide whether or not outcomes of test case executions are correct. The oracle problem refers to situations when either an oracle is not available, or it is too expensive to apply. Metamorphic testing has emerged as an effective and efficient approach to alleviating the oracle problem. This article introduces the basic...
In this paper, we present our experience of testing wireless embedded software. We used a wireless metering system in operation, and its software as a case study to demonstrate how a property-based testing technique, called metamorphic testing, can be used in detecting software failures of this wireless embedded system. Our study shows that a careful design of test environments and selection of system...
