scala - 如何测试正确模板的渲染

Question

我想测试我的应用程序是否在 play framework 2.3.x 中呈现正确的模板，例如:

"Index" should{
    "render index template" in new WithApplication{
      ...
      val result = call(controller.index, FakeRequest())
      someFunction(result) must render(views.html.index)
    }
}

类似于 rspec 所做的事情:

response.should render_template("success")

可以吗，推荐的玩法是什么？

对于像这样的简单 Controller 功能，我会检查响应的内容与渲染模板的内容。请注意，模板呈现为 Html，因此您必须调用 toString 来与 Result 的内容进行比较。我也喜欢检查 Result 的内容类型和状态。

"Index" should {
    "render index template" in new WithApplication {
        val request = FakeRequest(GET, '/') // I prefer using the router, but it doesn't matter that much.
        val Some(result) = route(request)
        val expectedContent = views.html.index().toString

        contentAsString(result) must equalTo(expectedContent)
        contentType(result) must equalTo("text/html")
        status(result) must equalTo(OK)
    }
}
