# This is test driver for testing two rsyslog instances. It can be
# utilized by any test that just needs two instances with different
# config files, where messages are injected in instance TWO and 
# (with whatever rsyslog mechanism) being relayed over to instance ONE,
# where they are written to the log file. After the run, the completeness
# of that log file is checked.
# The code is almost the same, but the config files differ (probably greatly)
# for different test cases. As such, this driver needs to be called with the
# config file name ($2). From that name, the sender and receiver config file
# names are automatically generated. 
# So: $1 config file name, $2 number of messages
# environment variable TCPFLOOD_EXTRA_OPTIONS is used to slowdown sending when
# using UDP (we've seen problems due to UDP message loss if sending with full
# speed)
#
# A note on TLS testing: the current testsuite (in git!) already contains
# TLS test cases. However, getting these test cases correct is not simple.
# That's not a problem with the code itself, but rather a problem with
# synchronization in the test environment. So I have decided to keep the
# TLS tests in, but not yet actually utilize them. This is most probably
# left as an exercise for future (devel) releases. -- rgerhards, 2009-11-11
