Let me check these example on Monday and get back to you (vibration and battery
are not APIs we use in our daily test automation because it's hard to validate
the input and output).
In the meantime if you want some examples of how we use the Python Marionette
client with Fx OS APIs you can look here:

Thanks Zac,
I think the real problem for me is that the javascript functions don't seem to
do what I expect.
vibrate() doesn't cause a vibration.
returning .battery doesn't return.
I tried execute_script first and that didn't work so I tried async.
Is it some sort of context or permissions problem?
FWIW I have a near constant stream of the following in logcat....
E/GeckoConsole( 109): [JavaScript Warning: "Empty string passed to
getElementById()." {file: "chrome://marionette/content/marionette-elements.js"
line: 164}]
My UI was stuck, i.e. screen black and not responding so I kill HUPd b2g to
recover.
Thanks,
Craig

Hi Craig, execute_async_script expects a callback from marionetteScriptFinished
and if doesn't get it it will time out.
If you use just execute_script instead of execute_async_script it should work.
Or I think you need to do
execute_async_script("marionetteScriptFinished(navigator.battery)")
(disclaimer untested as I don't have my phone here right now but I think you
can work it out!)

Subject: [b2g] marionette script "hanging" on simple javascript...
Maybe I'm not understanding something quite right but I was trying to write
some python/marionette scripts and the basics detailed here:
https://developer.mozilla.org/en-US/Firefox_OS/Platform/Automated_testing/Marionette_for_interactive_Python?redirectlocale=en-US&redirectslug=Mozilla%2FFirefox_OS%2FPlatform%2FTesting%2FMarionette_for_interactive_Python
Just don't seem to work... i.e. returning navigator.battery doesn't work, but
navigator.battery.level does. Making a phone call seems to work but vibrate
doesn't.
Any ideas why?
I'm running these scripts locally on my keon phone w/ debian installed as well
to provide python/gcc/etc...
Here's a script that doesn't do anything:
#!/usr/bin/python
from marionette import Marionette
marionette = Marionette('localhost',2828)
marionette.start_session()
result = marionette.execute_async_script("""
return navigator.vibrate(50);
""")
print(result)
Thanks,
Craig
