[tomfitzhenry]

uniqueItems, as described on https://github.com/swagger-api/swagger-spec/blob/master/versions/2.0.md is not supported.

Example usage:

Steps to reproduce

curl 'http://uniqueitems-support.swaggerific.io/

Expected

One of: [], ["foo"], ["bar"], ["foo", "bar"]

Actual

Sometimes I get duplicate entries, e.g. ["foo","foo","foo","bar"]

Oops. I raised this against the wrong project. See blinkboxbooks/genny#10

Thanks @tomfitzhenry, I've pushed PR blinkboxbooks/genny#12 to fix this, once that's tested & available I'll update swaggerific to follow suit :)

[jphastings]

PR #24 fixes this :)

I think there's a bug because I can't seem to get any lists with size greater than 1.

$ for i in $(seq 20); do curl 'http://uniqueitems-support.swaggerific.io/'; done
["foo"]["bar"]["foo"]["bar"]["foo"]["bar"]["bar"]["bar"]["bar"]["bar"]["bar"]["bar"]["foo"]["foo"]["foo"]["bar"]["foo"]["bar"]["foo"]["bar"]

I suspect this is a bug, but looking at the PR, I can't see where it is...

Maybe it's a case of http://i.imgur.com/U8eTUIw.jpg

I think it probably is :P Yeah, the tests pass but your use case still isn't working. Will check it out today :)
