Continuous quality assessment is crucial for the long-term success of evolving software. On the one hand, code analysis tools automatically supply quality indicators, but do not provide a complete overview of software quality. On the other hand, quality models define abstract characteristics that influence quality, but are not operationalized. Currently, no tool chain exists that integrates code analysis tools with quality models. To alleviate this, the Quamoco project provides a tool chain to both define and assess software quality. The tool chain consists of a quality model editor and an integration with the quality assessment toolkit ConQAT. Using the editor, we can define quality models ranging from characteristics down to operationalized measures. From the quality model, a ConQAT configuration can be generated that can be used to automatically assess the quality of a software system.
