Data flow testing of service choreography
2009
Proceedings of the 7th joint meeting of the European software engineering conference and the ACM SIGSOFT symposium on The foundations of software engineering on European software engineering conference and foundations of software engineering symposium - ESEC/FSE '09
Preserved Fulltext
By applying XRG patterns, we successfully identify new data flow associations in choreography applications and develop new data flow testing criteria. ...
Choreography specifies how services collaborate with one another by defining, say, the message exchange, rather than via the process flow as in the case of orchestration. ...
Data Flow Entities for Choreography This section proposes a family of data flow testing criteria to measure the quality of test sets for choreography applications. ...

In spite of all the benefits of choreographies, the decentralized flow of information, the parallelism, and multiple party communication restrict the automated testing of choreographies at design and runtime ...
In this paper, we present our first step in that direction, a software prototype composed of ad hoc automated test case scripts for testing a web service choreography. ...
Finally, some environment issues such as the non consolidation of choreography service standards, the decentralized flow of information, multiple party communication, and parallelism must be adequately ...

The selection of traces to use for test derivation purpose is driven by a specifically conceived technique to work flow refactoring which permits to reduce the number of interleavings to explore, in particular ...
This paper proposes a novel derivation strategy for test case skeletons, which can be successively refined and concretized to check the behaviour of parties willing to play a role within a choreography ...
Our work exploits the concept of SESE fragments and apply them to choreographies. A data flow technique to generate tests from service choreography specification has been proposed by [9] . ...

We propose a new conceptual model for choreographies of web-services. Choreographies are seen as virtual workflow models shared among participants. ...
Seller's Orchestration focuses only on the control flow aspects of a workflow definition. Because of lack of space we had to omit the data aspects. ...
