Silk Performer supports load testing of fat-client applications. To load test these applications, Silk Performer uses Microsoft Windows Terminal Services to connect to and open client sessions on agent computers. Via its own session manager, Silk Performer uses Silk4J, Micro Focus's functional testing tool, to test JUnit tests. Silk4J runs GUI-level tests and communicates results back to Silk Performer via the session manager. Silk Performer ultimately collects the results and makes them available to end-users.
GUI-level testing runs on supported Microsoft Windows Server platforms.
