Introducing the QCEP-testing system for executable acceptance test driven development of complex event processing applications

Abstract

In this paper we introduce the open source testing system QCEP-TS for realizing executable acceptance test driven development (EATDD) of complex event processing (CEP) applications. We will motivate the need of EATDD in this domain and argue that state of the art solutions do not address this topic or have substantial weaknesses. We show the design approach of our testing system including a vendor independent testing syntax. We also state relevant challenges for testing CEP applications and discuss implementation details of our solution. On the basis of a real world scenario we demonstrate first practical experiences of our solution. QCEP-TS is available as open source project at http://sourceforge.net/p/qcep-ts. QCEP (Quality Assurance of Complex Event Processing) is a collaboration project of the Munich University of Applied Sciences, the Technical University of Dresden and the UniCredit Business Integrated Solutions S.C.p.A.
