  1. IHE Testing Tools An overview

  2. The past (and current) • Mesa Tools • In house testing for Vendors • C++, Perl • Kudu • Connectathon management tool : • kind of speed dating software. Allows vendors to enter configuration and find test partners • Allow sponsor to control connectathon’s progress • PHP, Postgresql DB

  3. The Future (Gazelle) • Improve quality of testing • Introducing conformance testing where we only had interoperability testing • Unify Kudu and Mesa into one tool • Target to Vendors, Users and Sponsors • Opensource • Open and evolving architecture

  4. Interoperability / Conformance Specifications/Standards ConformanceTesting ConformanceTesting ImplementationA ImplementationB Interoperability testing VendorA Vendor B Projet IHE-Dev Inria Rennes

  7. Proxy

  8. Requirements • Capture messages exchanged between test participants • Shall be neutral : Non destructive message capture • Transmit captured messages to the Test Engine for further processing (EVS) • Provide information about sender and recipient when available Projet IHE-Dev Inria Rennes

  9. Proxy Design Test Engine Proxy SUT1 Port 2200 9201 SUT2 Port 104, 2000 9202 SUTa 9203 9204 SIMU1 Port 104 9205 SIMU2 Port 2004

  10. Design • Need to open a port for each responder • Transaction initiator may not know the responder real port • Proxy knows the responder based on the port used • Useful to provide more information that port and ip • Responder port may be mapped with more that one port on the proxy • Solution to isolate messages in the context of a test

  11. SUT1 participating to 2 tests Proxy Test Engine 9201 9202 SUT1 Port 2200 SUTa 9203 9204 9205 SUTb

  12. SUT1 participating to 2 tests Proxy Test Engine SUT1 Actor A and Actor B share the same port 9201 9202 SUTa 9203 9204 9205 SUTb Proxy maps an individual port for each config

  15. Proxy : First Experience • Proxy developed for the Oxford C.A.T • Capture of HL7 V2 messages only • Used under real conditions in Oxford • Messages transmitted to Kudu for call to EVS • NIST EVS • INRIA EVS • Usage of the proxy not required but recommended • Message captured and validation results available to participants through Kudu. Projet IHE-Dev Inria Rennes

  16. Proxy • Concept validated • Enable gathering of sample messages for validation of the EVS services • Improvements following Oxford C.A.T. • Capture of ACK messages • Extension to other protocols • XDS Messages • HL7 V3 • Dicom (more complex) Projet IHE-Dev Inria Rennes

  19. Specification Requirement • Use of Webservices • Definition of the API • Arguments, methods • Definition of XSD and XSL for arguments • Choice of MTOM for the transport of large objects like Dicom Projet IHE-Dev Inria Rennes

  20. EVS • Dicom : • DVTK based • Dicom3tools based • HL7 : • NIST • INRIA • IHE-J ? • CDA • NIST publish Schematron Projet IHE-Dev Inria Rennes

  21. HL7 EVS • 2 EVS available for the moment • NIST • INRIA • Validation based on HL7 Message Profiles • More than 140 Message profiles defined for exisiting IHE transactions • Profiles available from Kudu TF section while waiting for Gazelle Message profile repository Projet IHE-Dev Inria Rennes

  24. Test Engine • Mock up • TF -> ebXML-BP -> BPEL -> gestion des différents composants Projet IHE-Dev Inria Rennes

  25. Product Registry • Application Web • Objectifs : recherche de produits qui implémentent des profils d’intégration IHE • Sous composant de gazelle utilisant un sous ensemble des modules de gazelle • Permet de tester les choix, le modèle • Développé à Rennes Projet IHE-Dev Inria Rennes

  26. Gazelle Registration • Se base sur l’expérience du Product Registry • Portage de la partie enregistrement pour le connect-a-thon dans Gazelle • Doit être fonctionnel pour l’été (C.A.T NA) • Réalisé à Saint Louis et Rennes Projet IHE-Dev Inria Rennes
