Thank you for the explanation. Using `importlib` or to implement the code to test inside a Python module is indeed possible. However, I still prefer the `_launch.py` suffix, since this would conform to pep naming and enable unit tests without creating additional Python modules. I would also be interested to hear from users that moving from ROS1 to ROS2 if the `_launch.py` syntax feels unnatural compared to `.launch.py` or the other way around. --- [Visit Topic](https://discourse.ros.org/t/questioning-the-launch-py-file-extension/6352/5) or reply to this email to respond.
