I believe is_smooth turns on chrome tracing. We'll want to keep it off for some
energy benchmarks because it periodically wakes up threads to ask for their
trace data.

Done.

+    action_runner.Wait(20)
+    action_runner.ScrollPage()

[tonyg, 2014/10/15 23:26:49]

I don't believe they do the scroll, right? Adding the scroll here seems like a
better test to me, but I'd like to have one that faithfully reproduces and
another that we deem better.

I'd recommend energy.top_10_mobile (with scroll, mobile UA and top_10_mobile
page set) and energy.android_acceptance (no scroll, desktop UA, URLs you have,
and as a follow-up we should get them to load from the sdcard instead of WPR).

[sullivan, 2014/10/16 14:47:30]

Also, is it possible to structure this so we can use existing page sets like the
tab_switching benchmark does? It would be great to be able to do one-off
debugging in the future, for example running with the blank_page page set to
find unneeded work, or a polymer or service_worker page set to debug problems in
those features.

[rnephew (Reviews Here), 2014/10/16 17:02:24]

Done.

How do I get the websites to load to the SD card on telemetry tests? I've looked
around and can't see an obvious way to push data before the test runs.

[tonyg, 2014/10/15 23:26:49]

Why are we waiting for an element? AFAICT, we should have to wait for any
condition since we're just sitting idle. And waiting involves polling which is
going to affect energy consumption.

Done.

[sullivan, 2014/10/16 14:47:30]

Why desktop? Does the "real" acceptance test use a desktop user agent?

[rnephew (Reviews Here), 2014/10/16 17:02:24]

Added comment explaining why it uses desktop user agent.

[tonyg, 2014/10/15 23:26:49]

Is it possible to write a loop that does something like:

for url in ['url1',
            'url2',
            'url3']:
  self.AddPage(AcceptancePage(self, url))
