.travis.yml

# Generic .travis.yml file for running continuous integration on Travis-CI for
# any ROS package.
#
# Available here:
#   - http://felixduvallet.github.io/ros-travis-integration
#   - https://github.com/felixduvallet/ros-travis-integration
#
# This installs ROS on a clean Travis-CI virtual machine, creates a ROS
# workspace, resolves all listed dependencies, and sets environment variables
# (setup.bash). Then, it compiles the entire ROS workspace (ensuring there are
# no compilation errors), and runs all the tests. If any of the compilation/test
# phases fail, the build is marked as a failure.
#
# NOTE: The build lifecycle on Travis.ci is something like this:
#    before_install
#    install
#    before_script
#    script
#    after_success or after_failure
#    after_script
#    OPTIONAL before_deploy
#    OPTIONAL deploy
#    OPTIONAL after_deploy

# 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).
