所以根据Play 2.4文档(https://playframework.com/documentation/2.4.x/ScalaTestingWithScalaTest#Unit-Testing-Controllers),控制器应该设置为这样的特征
trait ExampleController {
this: Controller =>
def index() = Action {
Ok("ok")
}
}
object ExampleController extends Controller with ExampleController
为了让测试像这样工作
class ExampleControllerSpec extends PlaySpec with Results {
class TestController() extends Controller with ExampleController
"Example Page#index" should {
"should be valid" in {
//test code
}
}
}
然而,我使用Guice依赖注入,并根据Play 2.4文档(https://playframework.com/documentation/2.4.x/ScalaDependencyInjection),我的控制器如下所示:
@Singleton
class ExampleController @Inject() (exampleService: IExampleService) extends Controller {
def index() = Action {
Ok("")
}
}
由于控制器不再是特质,我无法将其混合到测试中:with ExampleController
,如何使测试成功?
答案 0 :(得分:3)
您可以直接从ExampleController继承。你也可以删除extends Controller
,因为你的控制器已经继承了这个:
class TestController(service: IExampleService) extends ExampleController(service)
您可以使用Play和Guice here
