Ah, nevermind; I tried to checkout lp:~javier.collado/ubuntu-test-cases/memory-usage-measurement as well (without the extra /utah), and that failed some minutes ago, but that was just due to LP being down.

So I checked out lp:~javier.collado/ubuntu-test-cases/memory-usage-measurement, installed {webbrowser,camera,mediaplayer}-app-autopilot, autopilot-touch, and smem and ran "autopilot run ubuntu_test_cases" in the "autopilot" subdir.

With that I get some failures:

I'm not sure whether the "RuntimeError: Unable to instantiate any backends" is relevant, but python-evdev is installed via autopilot-touch. Javier, do you get this as well?

The last "No such file or directory" is from probes.py and tries to call "smem-tabs", which is a program that doesn't exist (the smem package is installed, but it doesn't ship it). Javier, where does that come from?
