# Why are there <test> and matching <test>-exit-code tests
#
# A "limitation", i.e. a bug or misfeature, in ctest is that it tests
# REGULAR_EXPRESSION match OR exit code. For WILL_FAIL tests, failure is
# recognized by first attempting to match the FAIL_REGULAR_EXPRESSION
# and then checking the exit code. Thus if the app's exit-code is non-zero
# the test will fail regardless of whether the match succeeds. When the
# match succeeds ctests notes this in the LastTest.log. Nothing is noted
# about a failed match. Similarly for non WILL_FAIL tests, ctest tests
# PASS_REGULAR_EXPRESSION match OR exit code == 0.
#
# When failures occur all the KTX tools BOTH output a message, which
# we want to verify in these tests, and exit with a non-zero error
# code, which we also want to verify. We need a different test for
# each case. Perversely to test for the intended failure message we have
# to use a non WILL_FAIL test with a PASS_REGULAR_EXPRESSION so that
# when the PASS RE fails to match we are guaranteed the exit code
# test will fail. When it does match the exit code is not checked.
