Waterfall currently just says "test" on all test steps. It would be better to have a short description of each step, or even just the full text of the command for that step.

Buildbot docs at http://docs.buildbot.net/latest/manual/cfg-buildsteps.html#common-parameters describe description and descriptionDone, and here is an example of them in use.

Steps are created here with configs drawn from here.

@aneeshusa, what's your opinion on whether this should be implemented by adding the information to the yaml file or by inferring it from the commands?
