! !PROGRAM: ESMF_AttReadGridCompUTest - AttributeRead GridComp Unit Tests
!
! !DESCRIPTION:
!
! The code in this file drives F90 AttributeRead GridComp unit tests.
! The companion file ESMF\_Attribute.F90 contains the definitions for the
! AttributeRead methods.
!
!-----------------------------------------------------------------------------
! !USES:
      use ESMF_TestMod     ! test methods
      use ESMF         ! the ESMF Framework

      implicit none

!  The unit tests are divided into Sanity and Exhaustive. The Sanity tests are
!  always run. When the environment variable, EXHAUSTIVE, is set to ON then
!  the EXHAUSTIVE and sanity tests both run. If the EXHAUSTIVE variable is set
!  to OFF, then only the sanity unit tests.
!  Special strings (Non-exhaustive and exhaustive) have been
!  added to allow a script to count the number and types of unit tests.
