When doing an export of a test definition (to xml) there is always all the code coverage data(even after using Clean Up Results).
So when doing 20 times a run of the test definition ,the XML will end up with 20 code coverage info.
When cleaning up results we should remove appropriate code coverage data too in order to prevent creation extremely large export files.
Run the attached script BEFORE cleaning up doing with Quest Code Code Tester For Oracle.
Issue fixed in version 2.2.1. The latest version of Quest Code Tester For Oracle can be downloaded at : http://support.quest.com/Search/SearchDownloads.aspx
