Using one or more recordings, the Export pull-down menu includes a Screen Simulator script generation tool. Using this tool, a standalone script can be generated providing accurate navigation between each screen visited in the recording(s). By setting the generated script as the source for the active Screen Simulator service, the local Screen Simulator can be used to create and unit test Viewer-based .NET applications. This enables offline development, without the need for a host connection, or a test slice/region on the host to ensure data integrity during initial development and testing.
