You can add individual test scripts or entire packages of test scripts to a test execution package. To do this:
The package/script and all its contents will then be copied into the destination execution package/ plan. You can also move scripts within the execution packages and plans in the same way by dragging and dropping.
Changes made to an existing script in the script library will automatically update the corresponding script(s) in the execution set with the status of “Not Run”. Current and historical runs will not reflect the new changes. A new run of a previously executed script will reflect the new changes.
Test scripts can be copied from one project to another. Script Assignments in the Execution Set can only be created from scripts within the same project.
