Question

我试图使用play framework版本2.5.9对控制器进行功能测试。

我有一个名为HomeController的控制器

@Singleton
class HomeController @Inject()(implicit exec: ExecutionContext) extends Controller {
    def index = Action.async {
        Future{
            Ok(views.html.index("Home"))
        }
     }
}

我的观点看起来像这样

@(message: String)

@main("Home") {
    <h2>Welcome</h2>
}

@main中的参数是页面标题中的内容我的测试看起来像这样

class ApplicationTwoSpec extends PlaySpec with OneServerPerSuite with OneBrowserPerSuite with HtmlUnitFactory{

  implicit val ec = Implicits.global

  val homeController = new HomeController()

  implicit override lazy val app = 
    new GuiceApplicationBuilder()
      .router(Router.from{
        case GET(p"/") => homeController.index
      })
      .build()


   "The sample Controler with a server" must {

    "have home in the title" in {
      go to s"http://localhost:9000/"
      pageTitle mustBe "Home"
    }
  }

}

当我运行测试时，我回来了

must return and ok response back *** FAILED ***
"[]" was not equal to "[Home]" (ApplicationTwoSpec.scala:37)

我需要做些什么来让它得到适当的回应？

Answer 1

我在找到scala test plus和playframework的源代码后发现了问题。

go to s"http://localhost:9000/"

应该是

go to s"http://localhost:$port/"

在implicit lazy val port特征中指定OneServerPerSuite并从play.api.test.Helpers包中获取其默认值，默认为端口19001.如果我真的需要端口为9000我可以也可以使用

覆盖端口

implicit override lazy val port = 9000

如何使用功能测试在Play Framework中测试控制器
