# Convenience script to clean, build, install and run unit and/or integration tests.
# Recommend you run this prior to pushing to Github to reduce the chances of breaking
# the continuous integration (unit tests) or overnight builds (integration tests.)
#
# Also very useful when using "git bisect" to find out which commit was responsible
# for breaking the overnight build - invoke as "git bisect run ./buildAndRun"
#
# Run "./buildAndRun --help" to see the usage.
