I'd just make this an EXPECT. Generally we use ASSERT when continuing with the
rest of the test will produce cascading crashes, say due to a null pointer or
such. If it's just a matter of initial assumptions/expectations being wrong, no
harm proceeding with the test. So:
EXPECT_EQ(1, ...);

Done.

I recommend that you navigate to a known URL, such as "chrome://version". So you
can then check that the newly added tab's URL is indeed that (and that we didn't
just open a tab and navigate to a random URL).

Why not actually click on the page using ui_test_utils::ClickOnView(browser(),
VIEW_ID_TAB_CONTAINER)? The reason why I insist on actually clicking on the page
is that it has a bunch of ripple effects - omnibox losing focus,
InstantController trying to commit the preview, etc. I'd like to ensure that the
navigation reliably succeeds amidst all that.

[dougw, 2013/02/20 21:46:56]

Done.
