The Home Automation System (HAS) is a service-oriented application that facilitates the automation of a private home to improve the comfort and security of its residents. HAS is implemented using a service-oriented architecture. Many of the services in the HAS dynamically change their configuration during run-time. This occurs due to change in availability and bindings between services. Dynamic reconfigurations of services in the HAS presents several testing challenges, one being the specification of test oracles. In this paper, we give an approach for specifying test oracles for services in the HAS. We formally specify test oracles in the JML specification language. To verify service behavior in the presence of dynamic reconfigurations, we use mechanisms in the service architecture that notify dynamic changes along with run-time evaluation of JML specifications. We illustrate our approach using an example service in the H-Omega HAS developed on the OSGi™ and iPOJO service platform. To evaluate our approach, we developed a testing framework that allows for generation of tests with dynamic service reconfigurations. In addition, we seeded faults into the example service, and evaluated the effectiveness of the test oracles in revealing the faults using the generated tests.
