Even if I have been a little low on posts on technical parts of testing and test automation, this is something of an interest to me as well. For example, I have been doing some ruby/watir/cucumber gui automation testing. I really like cucumber and the intentions it has on communication between stakeholders.
This is actually also one of the intentions that my dear friend and colleague Renas Reda has with his new framework Robotium.
Robotium is a test framework created to make automatic black-box testing of Android applications significantly faster and easier than what is possible with Android instrumentation tests out-of-the-box.
With the support of Robotium, test case developers can write system and acceptance test scenarios, spanning multiple Android activities.
Inspired by cucumber, there are great plans to integrate with it or at least create the same kind of BDD syntax in Robotium. And I really like that idea.
Try it out, its open source at google code.
