Following servant-routes, I’ve uploaded a new package candidate servant-routes-golden. As the name suggests, the idea is to use the HasRoutes class to generate golden tests from API types.
A more thorough explanation is available in the README. As usual, any feedback is welcome, either in this thread or in the PR.
servant-routes-golden version 0.1.0.0 is now published. Enjoy 
Side note: if anyone can explain to me why hackage.haskell.org… is redirecting to hackage-content.haskell.org (e.g. when you click on Servant.Routes.Golden from the landing page of servant-routes-golden), I’d appreciate it!
I suspect it’s intended to quarantine user-generated content in a separate domain name. I can’t find any documentation about this behavior though.
