BPM-X offers a smart integration between all popular modeling tools such as ARIS, CaseWise, Visio, Sparx Enterprise Architect, IBM BlueWorks Live, OpenText ProVision and many others or BPM systems like TIBCO, Appian, Pega, WebSphere with HP ALM (QualityCenter, QC).
The integration supports:
Generating test cases by model-based testing automated from business process models (EPC, BPMN, UML, Swimlane or any other modeling language)
Combination of requirements coming between a modeling tool and HP ALM
Reverse decomposition to have real end-to-end testes out of complex business architectures down to implementation levels
Generating of BPMN models to be loaded into HP ALM requirements
By using the HP ALM web services REST API BPM-X can bi-directionally access all relevant data. More information you can find at http://www.bpm-x.com/solutions/model-based-testing-for-erp.html or http://blog.bpm-x.com/?s=ALM
Btw, as I can see integration with HP ALM by Catchlimited is discontinued.
