Combine this test with the one above? you're toggling the same value...

Maybe use a parameterized gtest here for old/new? TEST_P...

[ftang, 2016/04/29 22:37:03]

Acknowledged.

[msw, 2016/04/29 23:43:40]

I'm not sure why you wouldn't do this... the new UI won't  have the same test
coverage as the old UI here. Using a parameterized test would make coverage
equal and let you avoid duplicating test fixtures in a one-off manner.

[msw, 2016/04/30 02:12:59]

Please add TODOs and/or file a bug, this regresses test coverage.
