Nope, GetMainFrame() is non-const.

Nit: Would an EXPECT not be sufficient here?

[Jeffrey Yasskin, 2016/02/26 18:21:25]

We won't get useful errors from the rest of the test if the navigation failed,
which is what this is testing, but it also won't crash the test, so sure.

Heh, I have no idea how to indent .then() calls. I've added 2 spaces.

I have no idea either, but zero spaces seemed like too little :).
