CITLAB: A Laboratory for Combinatorial Interaction Testing

Although the research community around combinatorial interaction testing has been very active for several years, it has failed to find common solutions on some issues. First of all, there is not a common abstract nor concrete language to express combinatorial problems. Combinatorial testing generator tools are strongly decoupled making difficult their interoperability and the exchange of models and data. In this paper, we propose an abstract and concrete specific language for combinatorial problems. It features and formally defines the concepts of parameters and types, constraints, seeds, and test goals. The language is defined by means of XTEXT, a framework for the definition of domain-specific languages. XTEXT is used to derive a powerful editor integrated with eclipse and with all the expected features of a modern editor. Eclipse is also used to build an extensible framework in which test generators, importers, and exporters can be easily added as plugins.
