This feature is available in Catalyst, Enterprise, and Ultimate editions.
A Test Suite is a set of aggregated acceptance tests generated from an external test system. If your instance of VersionOne has been integrated with an external test system, you can relate projects in VersionOne using the Test Suite field. This allows you to see the results of the test runs without ever leaving the system.
The reference field stores the external test system's identifier for the test suite.
Backlog Items can move through the project hierarchy. Use the Release Planning page to move backlog items to a new project.
Backlog groups are defined within the context of a project. Define backlog groups at the highest level possible so they can be reused by all child projects at lower levels in the project hierarchy.
