IRIS supports CCDA and FHIR transformations out-of-the-box, yet the ability to access and view those features requires considerable setup time and product knowledge. The IRIS Interop DevTools application was designed to bridge that gap, allowing implementers to immediately jump in and view the built-in transformation capabilities of the product. 

In addition to the IRIS XML, XPath, and CCDA Transformation environment, the Interop DevTools package now provides:

• FHIR-SDA Transformation setup
• SDA-FHIR Transformation setup
• Bubbling up of FHIR validation errors
• Loading of required context fo

There are many applications for working with HL7 V2 messages, but the tools for working with XML in IRIS Management Portal and Cache Studio are limited. While plenty of external utilities and IDEs work with XML messages and even C-CDA documents, there is a compelling case for being able to test directly against the IRIS C-CDA framework. 

Testing within the IRIS environment provides the necessary context: 

• XML parser configuration
• XML namespace context
• Facility and OID setup
• IHE header handling
• The HS.IHE.Util, HS.Util.XSLTTransformer, and %XML.XSLT.Transformer packages
• Leveraging th

One of the pain points for maintaining HL7 interfaces is the need to run a reliable regression test upon deployment to new environments and after upgrades. The %UnitTest class allows unit tests to be created and packaged alongside interface code. Test data can also be maintained within the unit test class, allowing for quick and easily repeatable smoke-testing and regression testing.
