Root Cause

One or more test cases in the ROS2 package returned non-zero exit status, often due to assertion failures, missing dependencies, or runtime exceptions during test execution.

  1. Run colcon test with --event-handlers console_direct+ to see detailed test output and identify failing tests.

  3. Update test dependencies in package.xml and run 'rosdep install -i --from-paths src' to ensure all test packages are installed.

Dead Ends

Common approaches that don't work:

  1. Re-running colcon test without cleaning build artifacts 40% fail

    Stale test binaries or cached results may mask underlying failures; a clean rebuild is needed.

  2. Disabling all tests with --packages-select and --mixin skip-tests 80% fail

    This bypasses the problem without fixing it, leaving broken tests for later.

  3. Upgrading colcon-core to latest version 30% fail

    The error is test-logic related, not a colcon tool bug.
