I believe the constructor is run once for each of the *_TEST_F(), is that
correct?

I recommend ensuring |expected_title_| is reset at the start of each test. That
way re-ordering tests won't cause breaks due to side-effects from having called
site_expected_title().

[mmenke, 2011/08/03 00:53:22]

The constructor is indeed called once for each *_TEST_F.  In fact, for the
browser tests, each test is run in a new process, so we don't have to worry
about side effects.
