Even back at the sprint, we talked about the fact that though we don't know exactly what our android images will look like yet (so specifics are hard to plan around), we do have a pretty good idea that things like abrek are not going to be a good fit there. Additionally, there are other tests that may eventually need to run from the outside. For that matter, the boot test itself is exactly one of those things. If a system doesn't boot, we still want to capture the serial log and save it for later debugging. We certainly need, and have already discussed the fact that the dispatcher has a server component that drives execution of such things. This isn't, in any way, bypassing the dispatcher, but rather using a different interface of it to run a non-abrek based test.
Despite that, this is still a useful exercise, and many thanks to Jim for putting this together to show us a proof of concept for how we can run tests remotely on android systems! Thanks, Paul Larson
