Can you document that these return the final RFH?

Done.

Done.

[Charlie Harrison, 2017/04/24 19:18:26]

Just rename this NavigateFrame since it is pretty generic. Then you can
implement NavigateMainFrame as just "return NavigateFrame(url,
web_contents()->GetMainFrame());"

[jkarlin, 2017/04/25 15:56:51]

Good idea, done.

[Charlie Harrison, 2017/04/24 19:18:26]

Optional: Unless you really need the frame name, inlining a placeholder in this
method might make the tests a bit more readable.

[jkarlin, 2017/04/25 15:56:51]

It's needed, but I've cleaned up the strings to make them more readable.

[Charlie Harrison, 2017/04/24 19:18:26]

Optional: I know it's annoying to ask (hence why this is only optional), but
using "1" for the size in kb makes these tests hard to read, as it conflates the
size with the count. Would you mind changing it to something like "10" as a
default for size? It would make reading the expected histogram lines much
easier.

[jkarlin, 2017/04/25 15:56:51]
