For an interpreted language such as python, it's super important to test your code before you upload it to the robot, as even simple syntax errors or referencing a variable that doesn't exist can put your robot dead in the water. That's why for years RobotPy has had first-class support for running your robot code without the robot -- which makes it super simple to integrate with a online CI system like Travis-CI.

It would be nice if off-robot testing were a first-class concept for the other robot languages, and I think that improving that situation would have a bigger impact on teams. After all, not everyone has an extra RoboRIO lying around to run a CI system on... and really, you shouldn't be running your robot on internet-connected networks!
