Perhaps we can also add a --site-per-process test on the renderer side (e.g.,
render_view_browsertest.cc), which could verify that the RenderFrameProxy ends
up with the right state?

[alexmos, 2014/11/18 18:25:31]

Done -- please see RenderViewImplTest.OriginReplicationForSwapOut.  I could also
add something similar for the other two remote frame creation paths
(ViewMsg_New, NewFrameProxy), if I can figure out how to get those to work as
render view tests.

Thanks!

[Charlie Reis, 2014/11/13 18:00:57]

nit: This isn't a site per process test, so it's a little unusual to use
site_per_process_main.html.  Would something like files/frame_tree/top.html work
here?

[alexmos, 2014/11/18 18:25:31]

Done.  It doesn't matter to the test as long as there's at least one frame in
the file.
