Running Tests in ROS 2 from the Command Line

Build and run your tests

To compile and run the tests, simply run the test verb from colcon.

colcon test --ctest-args tests [package_selection_args]

(where package_selection_args are optional package selection arguments for colcon to limit which packages are built and run)

Sourcing the workspace before testing should not be necessary. colcon test makes sure that the tests run with the right environment, have access to their dependencies, etc.

Examine Test Results

To see the results, simply run the test-result verb from colcon.

colcon test-result --all

To see the exact test cases which fail, use the --verbose flag:

colcon test-result --all --verbose
