Question

Scala代码：

class Sender {
  def send(objects: Any): Unit = ()
}

class User(sender: Sender) {
  def hello(): Unit = {
    sender.send("hello")
    sender.send(1)
    sender.send(2)
  }
}

我只想测试它发送正确的整数，而不关心字符串：

"user" should {
  "send 3 objects, but two ints only" in {
    val sender = mock[Sender]
    val user = new User(sender)
    user.hello()
    there was two(sender).send(any[Int]) // !!! failed
    there was one(sender).send(1)
    there was one(sender).send(2)
  }
}

它失败并显示消息：

The mock was not called as expected: 
sender.send(<any>);
Wanted 2 times:
-> at com.mytest.UserSpec$$anonfun$13$$anonfun$apply$10$$anonfun$apply$1.apply$mcV$sp(UserSpec.scala:50)
But was 3 times. Undesired invocation:
-> at com.mytest.UserSpec$User.hello(UserSpec.scala:63)
java.lang.Exception: The mock was not called as expected:

如何以正确的方式写出来？

Answer 1

您可以使用haveClass来获得正确的匹配

there was two(sender).send(haveClass[Integer])

如何验证'发送者'在Mockito中只发送了'两个整数'？
