Why can't we use the mock method directly? For the NotNull check? xhwang, any
ideas to address that?
fgalligan, please at least add a comment.

[fgalligan1, 2013/03/13 19:36:52]

I added xhwang's todo and comment on why we can't use the mock method directly.

[xhwang, 2013/03/13 20:15:20]

Yeah, it's unfortunate that mock method doesn't work with move-only classes.
