For this patch, I've tried to observe the change of preference "dom.testing.tv_mock_data" to update the data in TVSimulatorService instead of add another test-only interface.
However, because TVSimulatorService is now in chrome process, the act after changing preference in content process cannot be sync with act of updating data from changed preference, I leave initData function to update data in TVSimulatorServer.

The following is the try result :
https://treeherder.mozilla.org/#/jobs?repo=try&revision=aa1199ee14e9&selectedJob=20031688

There are some failed tests, but these tests are not caused by these patches.

Sorry, had to back this out for build bustage like https://treeherder.mozilla.org/logviewer.html#?job_id=27051886&repo=mozilla-inbound I'm guessing this needs a rebase?

Hi Kit,

These patches will just land to B2G v2.6.
Thank you.

Comment 26

[Kevin Chen[:kechen] (UTC + 8)]

I will request for B2G 2.6 check in after testing on it.
