Rational ClearQuest Test Manager can support multiple test projects and concurrent releases.
The scope of any single test project is defined as follows:
When any configured test case record associated with a specific asset registry record is executed, the only possible iterations available to select are those associated with that asset registry record.
If the file location for a test script that is associated with any configured test case record is in Rational ClearCase® VOB, the iteration value selected at execution defines which Rational ClearCase view to use to access the test script.
For more information, see Using an asset registry record and Using an iteration record.
