An Extensible Framework for Testing Distributed Java Applications

Testing applications involves the creation of test sets, their execution, management and adequacy assessment. An extensible framework, called RiOT, has been developed to allow the implementation of tools for test coverage measurement, test execution management and fault-based testing of distributed Java applications. Test coverage is measured in terms of elements covered in the interface description of an application’s components. Mutation operators for interface mutation analysis are proposed and their implementation described. Fault injection testing for the assessment of the application’s fault tolerance properties is made possible using the fault injection mechanism of the framework. An extension of the framework to allow test monitoring and control is described. The framework uses a hierarchical form of data communication between its different modules. The framework is designed to be scalable and easily extensible for future enhancements.
