Abstract
In this paper the CitLab tool for Combinatorial Interaction Testing is presented. The tool allows importing/exporting models
         of combinatorial problems from/to different application domains, by means of a common interchange syntax notation and a corresponding
         interoperable semantic meta-model. Moreover, the tool is a framework allowing embedding and transparent invocation of multiple,
         different implementations of combinatorial algorithms. \citlab has been designed tightly integrated with the Eclipse IDE framework,
         by means of its plug-in extension mechanism. It is intended to easy the spread of CIT testing both in industrial practice
         and in academic research, by allowing users and researchers to apply multiple test suite generation algorithms, each with
         its peculiarities, on the same problem models, and let them compare the results in order to select the one that best fits
         their needs, while alleviating from the pain of knowing all the different details and notations of the underlying CIT tools.
