Lightweight Model-Based Testing for Enterprise IT

Model-Based Testing (MBT) popularity in IT is growing at a very slow pace. A recent survey stated that no more than 14% of respondents use MBT in their projects. Our experience, presented in this paper, demonstrates that the complexity in use of the current MBT approaches for the average tester is the main reason for this low dissemination. Then we introduce a lightweight MBT approach and a tool, called Yest, dedicated to business process-based testing of enterprise information systems. This tool uses a workflow-based graphical representation linked with decision tables to be used by functional testers without requiring any kind of modeling skill (such as UML for example). These approach and tool are dedicated to a particular class of applications (i.e. enterprise IT applications such as ERP and bespoke business applications). This focus strongly helps to simplify the approach and to adapt the tooling to the targeted users (namely IT functional testers). Finally, we discuss the way MBT may support emerging Acceptance Test Driven Development practices in agile.
