Restrictions

  o  You cannot delete a test description if it belongs to a group.
     Use the REMOVE TEST_DESCRIPTION command to remove a test
     description from a group. Use the SHOW TEST_DESCRIPTION/GROUPS
     command to display the groups to which the test description
     belongs.

  o  Do not delete a test description that is part of an existing
     collection. If you delete a test description that is part
     of a collection, you may see error messages when you issue
     other Digital Test Manager commands. For example, if you review
     a collection from which you have deleted a test description
     and its associated benchmark file for a noninteractive test,
     you will see a message indicating that the result description
     contains errors and you will be unable to examine the benchmark
     file for this result description. If you delete the test
     description and benchmark file for an interactive test that
     uses a screen comparison, you will be unable to examine any of
     the files associated with the test.
