IHE has a collection of tools for testing implementations of actors in IHE profiles.  You will find links to all tools for testing IHE profiles and their test descriptions on the complete Index to IHE Test Tools 

The test cases in this section are for a subset of IHE's tools and are generally organized in the menu at left according to the tool that is used.

User guides for tools associated with these test cases are here: http://gazelle.ihe.net/content/gazelle-user-guides

If you are preparing for an IHE Connectathon, Gazelle Test Management for your testing event contains a list of the Preparatory tests you must perform, customized according to the IHE profiles/actors/options you have registered to test.  You can find your list of Preparatory tests in Gazelle Test Management under menu Testing -->Test execution.  (For IHE European Connectathons, Gazelle Test Management is at https://gazelle.ihe.net/gazelle/home.seam; other testing events may have a diffeent URL).
