# FILE:				cros_sample_crossystem_test.sh
#
# DESCRIPTION: Tests crossystem command. Basic tests to demonstrate a cros
#							 test implemented as a bash script.
#
# AUTHOR:			 truty@chromium.org
#
# FULL REFERENCE:
#		http://ltp.sourceforge.net/documentation/how-to/ltp.php
#		Contents and organization of LTP.
#		Instructions for creating tests including:
#		-.c test template
#		-Bash test template
#
# QUICK REFERENCE FOR TEST WRITING:
# 1. Create a new test subdirectory with Makefile based on this one.
# 2. Exporting TST_TOTAL, TCID and TST_COUNT are required. Copy this setup().
# 3. Use $LTPTMP/... for storing files produced.
# 4. Clean the files up in cleanup() if possible.
# 5. Return 0 for success and nonzero for fail.
# 6. Use these command line api's to indicate test status:
#
#		 Informational messages:
#			 tst_resm TINFO "Informational message..."
#
#		 PASSED test:
#			 tst_resm TPASS "Test succeeded message..."
#
#		 FAILED test:
#			 tst_resm TFAIL "Test failed message"
#
#		 Unexpected infrastructure problem:
#			 tst_brkm TBROK <cleanup_fn or NULL> "Unexpected ... message"
#
#		 Flavors of these commands exist that can also emit a file to include
#		 detailed status as follows:
#			 tst_res <status> <fname> "tmessage..."
#			 tst_brk TBROK <fname> <cleanup_fn> "tmessage..."
#
#			 <tstatus> is one of:
#				 TINFO - informational message
#				 TPASS - test passed
#				 TFAIL - test failed
#				 TWARN - warning during the test
# 7. Add your test to $LTPROOT/runtest/cros_kernel_unittests
# 8. Modify INSTALL_TARGETS in the Makefile to match the new script.
