Add a new line below, or else sort-headers will mix it among the others.

Done.

I don't understand why you don't use BookmarkHomeViewController directly?

This was just copied from the other test class. Going with the real class now.
thanks

Optional nit:

EXPECT_EQ(nil, controller.menuView);

Using EXPECT_EQ/EXPECT_NE gives usually a better log when the expectation fails.

Done.

Related optional nit:

EXPECT_NE(nil, controller);
