Android Mockito.verify说参数不同！打印相同的内容 [英] Android Mockito.verify says Argument(s) are different! with printing same content

问题描述

情况

我有一个Tracker的接口，该接口具有以下方法:

I have an interface of a Tracker which has this method:

fun trackEvent(event: String, args: Bundle? = null)

我想验证是否使用特定的event调用了此方法. 在内部测试对象使用Bundle对象调用此方法. 所有事件均指定为

I want to verify, that this method is called with a specific event. Internally object that being tested call this method with Bundle object. All the events are specified as

companion object {
        const val EVENT = "EVENT"
}

问题

此验证失败，测试失败:

The test fails with this verification:

Mockito.verify(tracker).trackEvent(Tracker.EVENT)

带有消息:

参数不同！通缉: tracker.trackEvent("EVENT"，null); ...

Argument(s) are different! Wanted: tracker.trackEvent("EVENT", null); ...

实际调用具有不同的参数: tracker.trackEvent("EVENT"，null); ...

Actual invocation has different arguments: tracker.trackEvent("EVENT", null); ...

有很多解决方案，正在使用 Mockito.eq()，Mockito.refEq()，ArgumentMatchers，Captures等.它们对我都不起作用，给出相同的结果或NullPointerException

There are many solutions, which are using Mockito.eq(), Mockito.refEq(), ArgumentMatchers, Captures, etc. None of them worked for me, giving the same or NullPointerException

推荐答案

对于那些将面临相同问题的人，解决方案是您需要添加 build.gradle文件中的testImplementation "com.nhaarman:mockito-kotlin:1.5.0".更多信息，在这里 https://github.com/nhaarman/mockito-kotlin .

For those who will face same problem, the solution is that you need to add testImplementation "com.nhaarman:mockito-kotlin:1.5.0" in your build.gradle file. More info, here https://github.com/nhaarman/mockito-kotlin.

问题是，与Kotlin不同，在Java中所有类默认情况下都可以为空.尽管嘲笑被设计为与Java一起使用，但上面的库使用Mockito与Kotlin一起增加了支持.

The thing is that in Java all classes are nullable by default, unlike Kotlin. While mockito is designed to be used with Java, the library from above adds support using Mockito with Kotlin.

因此，此特定测试的解决方案

So, the solution to this particular test

Mockito.verify(tracker).trackEvent(Tracker.EVENT)

是

Mockito.verify(tracker).trackEvent(eq(Tracker.ADD_TRANSACTION), any())

其中eq()和any()是com.nhaarman.mockito_kotlin的功能.
