Interface faults injection for component-based integration testing

This paper presents a simple and improved technique of interface fault insertion for conducting component integration testing through the use of aspect-oriented software development (AOSD). Taking the advantage of aspect´s cross-cutting features, this technique only requires additional codes written in AspectJ rather than having a separate tool to perform this operation. These aspect codes act as wrappers around interface services and perform operations such as disabling the implementation of the interface services, raising exceptions or corrupting the inputs and outputs of interface services. Interface faults are inserted into the system under test to evaluate the quality of the test cases by ensuring not only that they detect errors due to the interactions between components, but they are also able to handle exceptions raised when interface faults are triggered.
