var path = require("path")

var api = require(__dirname + "/../../dadi/lib/api")
var Server = require(__dirname + "/../help").Server
var cache = require(__dirname + "/../../dadi/lib/cache")
var datasource = require(__dirname + "/../../dadi/lib/datasource")
var page = require(__dirname + "/../../dadi/lib/page")
var TestHelper = require(__dirname + "/../help")()
var config = require(path.resolve(path.join(__dirname, "/../../config")))

describe("Cache", function(done) {
  beforeEach(function(done) {
    TestHelper.resetConfig().then(() => {
      done()
