单元测试中的计数方法调用 [英] Counting method invocations in Unit tests

问题描述

在单元测试中计算方法调用的最佳方法是什么.任何测试框架都允许吗?

What is the best way to count method invocations in a Unit Test. Do any of the testing frameworks allow that?

推荐答案

听起来您可能想使用模拟框架通常提供的.expects(1)类型方法.

It sounds like you may want to be using the .expects(1) type methods that mock frameworks usually provide.

使用模拟，如果您正在测试列表，并且想验证是否使用这些参数调用了clear 3次，并且add至少调用了一次，您可以执行以下操作:

Using mockito, if you were testing a List and wanted to verify that clear was called 3 times and add was called at least once with these parameter you do the following:

List mock = mock(List.class);        

someCodeThatInteractsWithMock();                 

verify(mock, times(3)).clear();
verify(mock, atLeastOnce()).add(anyObject());
