Schedulable Online Testing Framework for Real-Time Embedded Applications in VM

The paper suggests a VM-based online testing approach in which software testing is piggybacked at runtime on a system that operates to serve actual mission. Online testing in VM is facilitated with a framework that uses persistence service to initialize the testing operation with a consistent system state. The testing operation then runs in an isolated domain which can be scheduled independently of the operating version. Thus, testing operation cannot cause unbounded pause time nor spoil the normal operation. We evaluate the feasibility of schedulable online testing with a prototype developed in MONO CLI (Common Language Infrastructure) and the experiment on the prototype.
