Java 在Mockito中验证交替调用

我正在为一个使用Java7 WatchService类特性的类进行单元测试。WatchService类提供一个take（）函数，该函数在下次目录发生更改时返回WatchKey对象。在下次调用WatchService上的take（）之前，必须重置WatchKey

Mockito提供了一个无序类来帮助处理这类事情，但它似乎不能很好地处理重复的交替

我最好的尝试

for(int i = 1; i < 4; i++){
    inOrder.verify(mockWatcher, atLeast(i)).take();
    inOrder.verify(mockKey, atLeast(i)).reset();
}
inOrder.verify(mockWatcher, times(4)).take(); // the last take() is interrupted before returning

验证此行为的标准方法是什么？

您可以尝试使用“应答”回调，使这些方法的“when”子句稍微复杂一些。在这个应答回调中，您可以利用一个共享数据结构来记录呼叫的顺序。切割完成后，您可以分析记录数据的正确性
