ESMF_TestResultsGather Subroutine

      subroutine ESMF_TestResultsGather(vm, localPet, petCount, testResults, &
        file, line, unit,  rc)

! !ARGUMENTS:
      type(ESMF_VM), intent(in) :: vm     ! the vm of this pet
      integer, intent(in) :: localPet     ! number of this pet
      integer, intent(in) :: petCount     ! number of pets
      integer, intent(in) :: testResults  ! test results for this pet
      character(*), intent(in) :: file  ! test file name
      integer, intent(in) :: line           ! test file line number
      integer, intent(in), optional :: unit ! additional output unit number
      integer, intent(out), optional :: rc ! return code

! !DESCRIPTION:
!     The gatherPet gathers the test results, PASS/FAIl, from all other
!     Pets and prints out a PASS/FAIL Message . This subroutine should
!     be called at the end of system tests and use test cases.
