    • The objective is not certification
    • There is no certification nor labelling from IHE
    • You can not write :
          – My system is IHE certified

                          More on registration

    • Please check the page :
          – Registration-> Registration Overview -> Profile coverage : This
            generates a report that list systems implementing the actors playing
            a role in each of the Integration Profiles.
    • I am giving you some warning on some profiles
          – « No actor »
    • Registration is evolving… many companies drop
      actors or IP as we reach the deadline for the logs
    • Please be warned and do not complain at
    • If you plan to drop, be nice let us know.

             Pre-Connectathon Testing

3 Feb 2012         Webinar for CAT Participants   15
                Why do we need test tools ?

    1. Reduce the number of systems to 80
       because the room we have reserved for the
       connectathon is too small !
    2. The project manager is evil and he likes to
       make you suffer with buggy mesa tools !
    3. The project manager like to spend his night
       checking logs
    4. Prepare your systems for the connectathon !

                Why do we need test tools ?

    • Test tools prepare you for the connectathon
          – Provides a minimum set of test to prepare your systems
    • Tools are a benefit of participation
          – As a participant you get them before the public release

                Why do we need test tools ?

    • Tests encourage you and your peers to read details
      of the Technical Framework
          – You may find you do not agree with our interpretation of the TF
          – You may not agree with the TF
    • If you and your peers complete the tests, we can
      avoid a lot of wasted time at the Connectathon
    • Thus we can prepare more complex demonstrations
      and do more complex connectathon tests

                               Test Coverage

    • Test software do NOT cover all aspects of the
      Technical Framework
    • Test software do NOT guarantee compliance
      with DICOM or HL7.
    • All what it does, is provide a reasonable
      preparation for the Connectathon.

                               I do not want …

    • Pre-CAT test do it this way, so I have
      implemented it this way !!!!!
          – WRONG
          – The Technical Framework shall be the reference !
          – Tools is one interpretation, it may be wrong

                                    How to

    1. First search in Gazelle the list of tests that is
       required for your system
    2. Upload the corresponding tools
    3. Read instructions for Installation
    4. Run the tests
    5. Returns test logs into Gazelle

                               Use of Gazelle

    • Gazelle provides
          – The list of test to be performed based on your registration
          – A GUI to return your logs.
    • Seems trivial :
          – Do not return logs for test you fail
          – If you do please provide explanation
    • Some tests are now automatically verified !

    • Where do I get the tools from ?
          – If you’re logged in you’ll get the last release
          – If not you’ll get the public release
    • Who writes the tools ?
          – MIR, Offis, NIST, U of Montreal, INRIA
    • Read the wiki

        Hardware/network requirement for
    • One computer system can :
          – Support all of the MESA actors
          – Can serve as the driver for any system under test.
    • Only one computer required to test an IHE
    • It is impossible to test multiple systems
          – (sockets are not multi-threaded).
    • You need to test separate systems serially
      with little or no reconfiguration.

        Recommendations for MESA Software

    • We recommend that you install and test the
      software as soon as possible
    • The authors try to make the installation
      process simple, but there will be some
    • It is better to go through a round of
      installation now rather than waiting until the
      “final/next” release is available;

                     MESA Test Interactions

    • Most MESA tests are independent of other
      tests. You can run them in any order.
    • Most tests overwrite common data areas.
      They do not overwrite the output of the
      evaluation scripts.
    • This implies you should run a test and
      perform the evaluation before starting another

                   General Test Instructions
    • Start MESA servers on test machine
    • Run an interactive perl script that leads you through
      the test scenario
    • Run a second perl script that evaluates your

    • How important is it ?
          – Most of the time spend in doing a connectathon test is spend
            checking/changing the configuration parameters.
          – More systems more choices of peers…. Try not to be the bad guy.

          – Proxy to be used.
    • Captures messages between peers
          – Allow logging of messages in a consistent manner
          – Allow validation of messages on the fly by Gazelle EVS

    • How does it work
          – Each responder will have a port map on the proxy
          – Initiator can send message to the responder or to the proxy.
