Test Case Library and Test Set Library
When building a product, you can reuse the same test case in multiple versions. A test case and a test set library help you in this task.
A test set library is a collection of test set trackers while a test case library contains test case trackers. The Test Set Library and the Test Case Library are available in the right pane of the Create Test Case or Edit Test Case page (for reusing test steps) and the Create Test Set or Edit Test Set page (for reusing test cases).
Using the filter for the tree you can filter the items by their status.
Configuring the Libraries
You can configure the libraries by clicking the 
icon above the trees.
icon above the trees.This displays the Configure Library dialog where you can select the trackers that you want to display in the library. Because this is a user-level setting, you will see the same list of trackers whenever you open the library.
 | Codebeamer stores the list of the selected trackers. When you add a new tracker to your project, you must reconfigure the library to display the newly added tracker in the list of trackers. The trackers of the current project are always displayed in the tree. |
