# This test injects a message and checks if it is received by
# imjournal. We use a special test string which we do not expect
# to be present in the regular log stream. So we do not expect that
# any other journal content matches our test message. We skip the 
# test in case message does not make it even to journal which may 
# sometimes happen in some environments.
