Planned Activities• Types of Tasks
– Analysis– Design– Development– Verification
• Areas of Focus– Testing Methodologies– Test Plans– Test Data– Vocabulary– LIS Test System– EHR LRI Reference Implementation
• For each area of focus we’ll perform an analysis and design to identify specific tasks
• Some areas of focus will become sub-groups (e.g., test data)
![Page 9: Lab Results Interface Validation Suite WG July 28, 2011](https://reader035.vdocument.in/reader035/viewer/2022081419/5697bf831a28abf838c86373/html5/thumbnails/9.jpg)
Overview of Focus Areas I
• Testing Methodologies– LIS systems and EHRs supporting the LRI implementation guide– Approaches
• Inspection Testing, Automated Tested, Combination • How do we test vocabulary?
• Test Plans– LIS systems and EHRs supporting the LRI implementation guide– End-to-end process– Range of test cases
• Test Data– Identify common-typical use cases from in-scope lab results– Support the range of message content (e.g., multiple results in a single message)– Data must be relevant and realistic (e.g., use correct code for result)– Community to decide level that is important, breadth, and depth

Overview of Focus Areas II
• Vocabulary– Collect and organize all specified vocabulary– Develop a common format to represent and provide APIs to access– Common component for tooling
• Lab System Test Tools– LIS Validation Engine– LIS Simulation
• Test Harness to test EHR systems• Generate/Send messages to EHR System• Create/Generate testing artifacts
• EHR Reference Implementation– At minimum capable of parsing, mapping, and displaying received lab results– Verify that the LRI IG is implementable– Phase 2 may add functionality (e.g., generate a PH lab message)
