Mockito 不再验证交互，但省略 getter

Mockito api 提供了方法：

Mockito.verifyNoMoreInteractions(someMock);

但是在 Mockito 中是否可以声明我不希望与给定的模拟进行更多交互，但与其 getter 方法交互除外？

在一个简单的场景中，我测试 SUT 仅更改给定模拟的某些属性，而保留其他属性未开发。

在示例中，我想测试 UserActivationService 是否更改 User 类实例上的 Active 属性，但不对 Role、Password、AccountBalance 等属性执行任何操作。

Mockito api provides method:

Mockito.verifyNoMoreInteractions(someMock);

but is it possible in Mockito to declare that I don't want more interactions with a given mock with the exceptions of interactions with its getter methods?

The simple scenario is the one in which I test that the SUT changes only certain properties of a given mock and leaves other properties untapped.

In example I want to test that UserActivationService changes property Active on an instance of class User but does't do anything to properties like Role, Password, AccountBalance, etc.

不，Mockito 目前没有此功能。如果您经常需要它，您可以使用反射魔法自己创建它，尽管这会有点痛苦。

我的建议是使用 VerificationMode 验证您不想频繁调用的方法的交互次数：

@Test
public void worldLeaderShouldNotDestroyWorldWhenMakingThreats() {
  new WorldLeader(nuke).makeThreats();

  //prevent leaving nuke in armed state
  verify(nuke, times(2)).flipArmSwitch();
  assertThat(nuke.isDisarmed(), is(true));
  //prevent total annihilation
  verify(nuke, never()).destroyWorld();
}

当然，WorldLeader API 设计的敏感性可能值得商榷，但作为示例，它应该做。

No this functionality is not currently in Mockito. If you need it often you can create it yourself using reflection wizzardry although that's going to be a bit painful.

My suggestion would be to verify the number of interactions on the methods you don't want called too often using VerificationMode:

@Test
public void worldLeaderShouldNotDestroyWorldWhenMakingThreats() {
  new WorldLeader(nuke).makeThreats();

  //prevent leaving nuke in armed state
  verify(nuke, times(2)).flipArmSwitch();
  assertThat(nuke.isDisarmed(), is(true));
  //prevent total annihilation
  verify(nuke, never()).destroyWorld();
}

Of course the sensibility of the WorldLeader API design might be debatable, but as an example it should do.
