Can you add description explain what this story does in details? Similar to
https://cs.chromium.org/webrtc/src/tools/perf/page_sets/system_health/browsin...

[ssid, 2017/04/13 21:08:54]

Done.

+    app_ui = action_runner.tab.browser.app_ui
+    platform = action_runner.tab.browser.platform
+    app_ui.WaitForUiNode(resource_id='url_bar')
+    url_bar = app_ui.GetUiNode(resource_id='url_bar')
+    url_bar.Tap()
+    action_runner.Wait(1) # user wait before typing
+    platform.android_action_runner.InputText('drake')

+    action_runner.WaitForNavigate(15)

why is this 15 seconds? Can you make this wait to be more deterministic by
changing it to wait for some element (maybe an extra few seconds after that if
you think it make the flow looks more realistic)

[ssid, 2017/04/13 21:08:54]

I didn't know this argument was not required. removed.

+    action_runner.ScrollPage(use_touch=True, distance=500)

[nednguyen, 2017/04/11 22:24:10]

The story below does more than this. Can you improve the documentation?
