NIST Conformance Testing § Reference Database of HL 7 Data Items § Tool for automatic creation of test messages § based on profile (XML), reference database § message variation § Testing Framework § simulated HIS node § send and receive messages § validation (messages and state of the database)

Reference Database § Contain sample entries for all HL 7 data items § § range of values simple, complex, boundary, valid, invalid XML format some data created automatically § Tables § HL 7 Tables § User Tables (HL 7 suggested values) § User Tables (NIST created or actual) § Code Sets

Message Maker § Creates test messages § based of profile § range of messages (minimal to fully populated) § variation of data values § valid and invalid § description of test purpose § Messages § Displayable as XML, ER 7, Enhanced ER 7 § Batch file (initially) § Can be edited

Message Maker Features § User can create message “by-hand” (select data items from DB) § Edit existing messages § String messages together into test scenarios § Control granularity and test case types § Import database § Modify reference database

Questions and Issues § How important is it to have “sensible” data (e. g. , a pregnant male)? Syntactically? Semantically? § Are there cases where it is important? § What are the important aspects to test? Any known problem areas? § Sources of example data; table data? § Conformance schema—add to profile? § What features should be added? § Sample requirements list?
