“…The goal is to facilitate maintainability and traceability of the testing by keeping the test cases and the test material closely linked together with the component, which, as observed in [3] are very important properties when dealing with complex projects. For instance it permits to keep the unit tests that the developer used for validating the component all along the lifecycle of the component.…”

Systems of Systems are large-scale information centric component-based systems. Because they can be more easily expressed as an information flow, they are built following the data-flow paradigm. These systems present high availability requirements that make their runtime evolution necessary. This means that integration and system testing will have to be performed at runtime as well. Already existing techniques for runtime integration and testing are usually focused on component-based systems which follow the client-server paradigm, and are not well suited for data-flow systems. In this paper we present virtual components, a way of defining units of data-flow behaviour that greatly simplifies the definition and maintenance of integration tests when the system evolves at runtime. We present and discuss an example of how to use virtual components for this purpose.

“…The nature of event‐based systems and service compositions poses difficult challenges to testing and debugging . For instance, event correlation is necessary to ensure that incoming event messages are associated with the correct processing element, but this mechanism has proven to be complex and often error‐prone (e.g.…”

SUMMARYThis paper addresses integration testing of data‐centric and event‐based dynamic service compositions. The compositions under test define abstract services that are replaced by concrete candidate services at runtime. Testing all possible instantiations of a composition leads to combinatorial explosion and is often infeasible. We consider data dependencies between services as potential points of failure and introduce the k‐node data flow test coverage metric, which helps to significantly reduce the number of test combinations. We formulate a combinatorial optimization problem for generating minimal sets of test cases. On the basis of this formalization, we present a mapping to the model of FoCuS, a coverage analysis tool. FoCuS efficiently computes near‐optimal solutions, which are used to automatically generate test instances. The proposed approach is applicable to various composition paradigms. We illustrate the end‐to‐end practicability based on an integrated scenario, which uses two diverse composition techniques: on the one hand, the Web Services Business Process Execution Language and on the other hand, WS‐Aggregation, a platform for event‐based service composition.

“…Several systematic test design techniques and testing approaches have been developed to assist in systematically exploring the available choices and selecting a representative sample (Beer and Heindl 2007). Criteria for selecting such a sample in safety critical systems are typically based on requirements, system models, control flow, data flow and an operational profile.…”
