# File :        eject_tests.sh
#
# Description:  Tests basic functionality of eject command.
#
# Author:       Manoj Iyer, manjo@mail.utexas.edu
#
# History:      Jan 01 2003 - Created - Manoj Iyer.
#                           - Added - Test #2.
#               Jan 03 2003 - Added - Test #3.
#               Jan 06 2003 - Modified - Test #3.
#                           - Changed tst_brk to use correct parameters.
#                           - Check if $LTPTMP/cdrom directory exists before
#                             creating it.
#                           - Corrected code to check if return code is not 0
#                             which indicated failure.
#                           - fixed code to add $LTPTMP/cdrom to /etc/fstab
#               Jan 07 2003 - Call eject with -v for verbose information.
#                Jan 08 2003 - Added test #4.
