For smokey to pass with the branch we need this merged:

https://github.com/alphagov/pp-smokey/pull/32

Since merging the redis stuff my tests are failing locally. Not sure about travis but I think they'll be okay there - I just need to set up redis properly locally or get my dev vm working again I assume. Is it worth not having this dependency in test though?

Also, it might be worth doing the data set list by group and type in henry's designs here or in a separate pull request. Input on this too please.
