json package:hspec-wai-json

A QuasiQuoter for constructing JSON values. The constructed value is polymorph and unifies to instances of FromValue. When used as a ResponseMatcher it matches a response with
  • a status code of 200
  • a Content-Type header with value application/json
  • the specified JSON as response body
When used as a ByteString it creates a ByteString from the specified JSON that can be used as a request body for e.g. POST and PUT requests. Example:
>>> L.putStrLn [json|[23, {foo: 42}]|]
[23,{"foo":42}]
