scala特性中的specs2模拟方法从未验证

Question

我正在尝试模拟我与外部API的交互，该API检查令牌以查看用户是否有权执行某些操作（它目前是一个单独的API作为PoC，稍后将移动到中间件中）

受抚养人（SBT DSL）

"org.specs2" %% "specs2-core" % "4.2.0" % Test,
"org.specs2" %% "specs2-mock" % "4.2.0" % Test

测试

class MyHandlerSpec extends Specification with Mockito {
   def is = s2"""
     The first step is to check if the lambda is called on behalf of an 
     authenticated user. This is done by verifying that user token provided 
     as the Authorization header is valid by calling the auth API.

     Here, we can ${ConfirmThat().authLambdaWasCalled} by the handler
   """

 case class ConfirmThat() {
   def interactions = mock[Interactions]

  def authLambdaWasCalled = {
    val reqHandler = Request[Input](
       headers = Map[String, String](
          "Authorization" -> "Bearer gagagaga"
       )
      // millions of values that are not directly related
    )
    MyHandler.handler(reqHandler, null)
    there was one(interactions).authenticateUser(Some("gagagaga"))
  }
 }
}

代码

代码使用了一个MyHandler类，该类扩展了trait Interactions:

 trait Interactions extends MyServiceTrait with AuthServiceTrait {
    def authenticateUser(token: Option[String]): Future[Either[Errors, Boolean]] = {
  Future.successful(Right(true))
 }
}

class MyHandler extends Interactions with Utils {

  override def handler(request: Request[Input], c: Context): Response[Errors, Output] = { 
    //  get the auth token from the headers as an option, 
    //  there is a method in Utils that I unit tested
    //  it been omitted here for clarity

    val authFuture = authenticateUser(bearerToken)
  }  
}

错误

当我运行代码时，我看到以下错误：

The mock was not called as expected: 
[error]  Wanted but not invoked:
[error]  interactions.authenticateUser(
[error]      Some(gagagaga)
[error]  );
[error]  -> at com.lendi.lambda.MyHandlerSpec$ConfirmThat.$anonfun$authLambdaWasCalled$1(MyHandlerSpec.scala:71)
[error]  Actually, there were zero interactions with this mock. (MyHandlerSpec.scala:71)

我如何确保我可以：

a）将身份验证代码移动到MyHandler中，并使用Specs2提供的Mockito对MyHandler进行部分模拟

b)确保我模拟了交互并将交互注入到代码中，以便处理程序可以正确地模拟它。

c）使用DI框架（我应该为我的lambda使用Spring）注入交互并使用DI框架模拟它。

Answer 1

您需要将模拟对象传递给MyHandler

class MyHandler(interactions: Interactions) with Utils

然后

val interactions = mock[Interactions]
val myHandler = MyHandler(interactions)

MyHandler.handler(reqHandler, null)
