nit: inline test_server()->GetURL(kSimplePage) in NavigateToURL below.

Focusing the location bar seems unnecessary here; remove this and the
EXPECT_TRUE directly below. (otherwise fix the indentation here)

Add a similar check for the 'v' (previous) button (pressing tab again).

Fix indentation... You'll also need to update this expectation if you fix the
behavior as I suggested in the other file.

Please add a similar test for mouse events.

[Deepak, 2015/08/27 05:31:04]

I have tried to add mouse event test case, But for that I need to have '/\' and
'\/' button position to send mouse click position. Currently these values are
not available as these buttons are private in find_bar_view.h.
I will add functions to get these while making clean up and making patch for
your suggestion mentioned in other file.
