IHE Testing ToolsAn overview
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
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

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

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

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.

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)

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
