# Compile and test (mark the build as failed if any step fails). If the
# CATKIN_OPTIONS file exists, use it as an argument to catkin_make, for example
# to blacklist certain packages.

# NOTE on testing: `catkin_make run_tests` will show the output of the tests
# (gtest, nosetest, etc..) but always returns 0 (success) even if a test
# fails. Running `catkin_test_results` aggregates all the results and returns
# non-zero when a test fails (which notifies Travis the build failed).
