# Notes on test settings:
# - CYCLONEDDS_URI:
# - EnableExpensiveChecks: for the few horrendously expensive (but pretty thorough)
# integrity checks, in particular on the WHC and the RHC, but there may be more
# - config to stderr: gives the configuration used when running the test in conjunction
# with "--output-on-failure" (sadly that still doesn't output the failed
# assertions ...)
# - -j 4: run 4 tests in parallel, this saves quite a bit of time because the VMs are
# all dual-core
# - --output-on-failed: print whatever output the test generated when it failed, which
# can obviously be quite helpful for debugging
# - -E ...: regex of tests to exclude:
# CUnit_ddsrt_random_default_random: performs a Chi-square test on the output of
# the random generator, but this does produce the odd failure (it should!). The
# code has been vetted, the test has been run a great many times (with the odd
# failure), and so we now simply skip the test to avoid the spurious failures.
