1. Option use-current-setup applies to the whole pbs_benchpress run and not to a single or subset of tests of a test run.
2. If no PBS configurations are altered on a test set up; then there is no effect of "use-current-setup" option on the test run.
3. load_configuration() will take care of setting the configuration back if not set, i.e. if res1 is not present create it, else if res1 is present do not create it.
4. Ideally a test that needs mandatory configurations should have a check for the same at start and should not continue if it is absent.
5. The test_execution user, MGR_USER and OPER_USER added during the setupclass does not get reverted.
