If you're interested in writing testable robot code, please see
this announcement in the Java forum about Strongback, a new open source Java library for FRC robots.
Strongback is based on work that FRC4931 presented at the 2015 FIRST World Championship Conference entitled "Designing Testable Robot Code". There was a lot of interest at the conference, including several teams that use C++.
Although we started with Java, the Strongback community would love to have a C++ library that follows the same principles and concepts, but to do that we need your help. If you are interested, please add your voice to
this discussion thread on our developer's forum.
