WCF service and Biztalk service configuration error

I have a WCF web service which calls a biztalk service( ie Orchestration). When i do the unit test i am getting following error:

Test method Goudse.BcVerzekering.Bts2006.InkCol.Business.UnitTests.UnitTest1.VerzekeringFacade_Goed threw exception: System.ServiceModel.FaultException: The binding at system.serviceModel/bindings/wsHttpBinding does not have a configured binding named 'WSHttpBinding_ITwoWayAsync'. This is an invalid value for bindingConfiguration. (C:\Inetpub\DeGoudse.MKB\VerzekeringFacade\web.co开发者_运维技巧nfig line 50).

Its pointing to web.config, but which is generated by the system itself...

Any insight will be very helpful?

Have you looked here? It should be added to the app.config to work properly.
