"How do I get Jenkins to run the tests for every branch, not just master?"
Turns out that's the default behavior of Jenkins. You can "Branches to build" to "*" in the build options. CI boxes spun up by Lobot sets that to 'master' by default.
However, if you have a persistent branch other than master that needs ci, it's probably better to just make another build than have Jenkins build all branches always.
