功能测试使用 scalatest 播放服务

Question

我已经使用 play 2.5 开发了 RESTful 服务，并且我正在尝试为我的服务开发功能测试。我正在关注官方文档here todo 。

这是控制器的测试：

package com.x.oms.controller

import org.scalatestplus.play._
import play.api.inject.guice.GuiceApplicationBuilder
import play.api.mvc.Action
import play.api.mvc.Results._
import play.api.routing.Router
import play.api.test.Helpers.{GET => GET_REQUEST}

class Test extends PlaySpec with OneServerPerSuite {
  implicit override lazy val app =
    new GuiceApplicationBuilder().router(Router.from {
      // TODO: Find out how to load routes from routes file.
      case _ => Action {
        Ok("ok")
      }
    }).build()

  "Application" should {
    "be reachable" in {

      // TODO: Invoke REST services using Play WS

      // TODO: Assert the result
    }
  }
}

这里是控制器：

package controllers.com.x.oms

import com.google.inject.Inject
import com.x.oms.AuthenticationService
import com.x.oms.model.DBModels.User
import com.x.oms.model.UIModels.Token
import play.api.Logger
import play.api.libs.json.Json
import play.api.mvc.{Action, Controller}

class AuthenticationController @Inject()(as: AuthenticationService) extends Controller {

  private val log = Logger(getClass)

  def authenticate = Action(parse.json) {
    request =>
      val body = request.body
      val username = (body \ "username").as[String]
      val password = (body \ "password").as[String]

      log.info(s"Attempting to authenticate user $username")
      val token = as.authenticate(User(username, password))
      log.debug(s"Token $token generated successfully")
      token match {
        case token: String => Ok(Json.toJson(new Token(token)))
        case _ => Unauthorized
      }
  }

  def logout = Action {
    request =>
      val header = request.headers
      as.logout(header.get("token").get)
      Ok("Logout successful")
  }

  def index = Action {
    request =>
      Ok("Test Reply")
  }

}

路线文件：

# Routes
# This file defines all application routes (Higher priority routes first)
# ~~~~

POST        /login         controllers.com.x.oms.AuthenticationController.authenticate
POST        /logout        controllers.com.x.oms.AuthenticationController.logout

GET         /              controllers.com.x.oms.AuthenticationController.index

我不想在每个测试中重新定义路线信息。在每次测试中构建应用程序时，我需要您的帮助来加载路由文件。

请告诉我如何加载路由文件。提前致谢。

我建议您在 Play 基础架构之外测试您的 AuthenticationService。如果您希望自己测试控制器，它们只是您可以新建并使用FakeRequest 直接调用的类：

val api = new AuthenticationController(as)

"fail an authentication attempt with bad credentials" in {
  val request = FakeRequest(POST, "/login")
    .withJsonBody(jsonBadCredentials)
  val result = call(api.authenticate(), request)
  status(result) mustBe UNAUTHORIZED
}
