Having come from a ‘test first’ background, this is a little frustrating that things are assumed to work. There are however several commands (scattered around in the documentation) that will help here. I documented some of them here:
The wiki on Docker has some useful commands for checking that Docker is correctly running. If things are good here, go to the next level down and check out the Ros. Shell into Docker, initializing the bash session, and checking the Ros topics. Much more than this requires setting up specific scripts for particular fixtures, etc.
It would nice to see a full regression test for the standard v2.0 computer, but it looks like it still needs to be built (do you want to volunteer?).
