Automate ROS 2 simulation tests in headless CI by orchestrating Gazebo environments with launch_testing to validate navigation and control loops, running colcon test to ensure deterministic integration testing.

Launch_testing in ROS 2 integration testing launches and orchestrates Gazebo-based simulations, enabling deterministic validation of perception, navigation, and control loops across different robot platforms and distributions.

Yes, you can run Gazebo simulation tests for Nav2 workflows in CI by creating end-to-end integration tests with launch_testing that execute reliably in headless environments using colcon-based workflows.

Reliably reproduce ROS 2 simulation failures for regression testing by executing integration tests in deterministic Gazebo simulation environments, replacing slow and unreliable real hardware checks with reproducible scenarios.

To set up colcon-based CI workflows for ROS 2 simulation testing, you need a ROS 2 package with YAML frontmatter defining name and description, using Python-based tests via launch_testing to run with colcon test.
