I am currently engaged in a ROS2 project aimed at optimizing our testing process…es by enabling concurrent execution of tests within a single package using `colcon test`. Initially, I attempted to utilize the `--parallel-workers` flag. However, this approach did not resolve the issue as intended. It facilitates parallel execution across multiple packages, but intra-package test execution remains sequential. Each test is implemented using the [launch_testing](https://index.ros.org/p/launch_testing/) framework and integrated into `colcon` via the `add_launch_test` macro within the `CMakeLists.txt` file. Key specifics include: - ROS2 version: Humble - Operating System: Ubuntu 22.04 - Test execution command: `colcon test` I am seeking guidance or practical examples that outline best practices for achieving concurrent test execution at the ROS2 package level. In case what I am asking turned out to be not supported, I suggest to add it to the list of desired features to be implemented. Thank you in advance!
