This has expanded a little and also adds reviews and requested reviews, so users can make sure there is at least x reviewers requested/made

Sorry, I'm my honeymoon - so it's taking a while to get around to looking at all these PRs - but my wife is asleep, and I got some time, so I'll clone this and see if I can grok what's up with the tests

[deecewan]

no rush. enjoy yourself :)

i haven't had time either. i'll take a look when I have a minute if you don't get round to it.

cool, looks like these functions need to be mocked out in some existing tests, and ideally adding some to cover the API calls, will add them

@orta I'm returning from a five-week hiatus, so I'll look to get involved in open issues and PRs over the course of this work week. Hope you have a great honeymoon!

[deecewan]
