Code review comment for lp:~jkakar/launchpadlib/fake-launchpad

Graham:

I keep thinking about this but I've also kind of lost steam on it
since it's been sitting here for ages. I'd love for it to be merged
because the lack of testability in launchpadlib is a big problem. My
feeling is that the API exposed to users of the test class is good but
that the internal details could be improved, as Leonard points out.
I'd like to see it landed and improved with subsequent branches, since
it's already useful.
