Helpers to test WAI applications with Hspec

Example

{-# LANGUAGE OverloadedStrings, QuasiQuotes #-}
module Main (main) where

import           Test.Hspec
import           Test.Hspec.Wai
import           Test.Hspec.Wai.JSON

import           Network.Wai (Application)
import qualified Web.Scotty as S
import           Data.Aeson (Value(..), object, (.=))

main :: IO ()
main = hspec spec

app :: IO Application
app = S.scottyApp $ do
  S.get "/" $ do
    S.text "hello"

  S.get "/some-json" $ do
    S.json $ object ["foo" .= Number 23, "bar" .= Number 42]

spec :: Spec
spec = with app $ do
  describe "GET /" $ do
    it "responds with 200" $ do
      get "/" `shouldRespondWith` 200

    it "responds with 'hello'" $ do
      get "/" `shouldRespondWith` "hello"

    it "responds with 200 / 'hello'" $ do
      get "/" `shouldRespondWith` "hello" {matchStatus = 200}

    it "has 'Content-Type: text/plain; charset=utf-8'" $ do
      get "/" `shouldRespondWith` 200 {matchHeaders = ["Content-Type" <:> "text/plain; charset=utf-8"]}

  describe "GET /some-json" $ do
    it "responds with some JSON" $ do
      get "/some-json" `shouldRespondWith` [json|{foo: 23, bar: 42}|]
