Bpm-x (www.bpm-x.com) offers integration with HP ALM (Quality Center) for all leading modeling tools such as ARIS 7.x/9.x, IBM Rational System Architect, ProVision, CaseWise, MEGA, iGrafx, Sparx System Architect, Visio 2010/2013 and others. BPM-X converts the native tool model formats or standards such as XPDL or BPMN into the HP ALM format.
Also it translates the different versions to fit into HP ALM required format. along loading the model into the requirements BPM-X offers a cool feature to generate linearized test cases with a technology called model-based testing (MBT). By this approach the test cases are automatically generated and loaded into HP ALM. Please refer also to our blog http://blog.bpm-x.com/?tag=model-based-testing
