使用 Mockito 验证方法后没有调用任何内容

2022-01-08 00:00:00 mocking unit-testing mockito java

我正在使用 Mockito 编写 Java 单元测试，我想验证某个方法是否是对象上调用的最后一个.

I'm using Mockito to write a unit test in Java, and I'd like to verify that a certain method is the last one called on an object.

我在被测代码中做了这样的事情:

I'm doing something like this in the code under test:

row.setSomething(value);
row.setSomethingElse(anotherValue);
row.editABunchMoreStuff();
row.saveToDatabase();

在我的模拟中，我不关心编辑行中所有内容的顺序，但重要的是我不在保存后尝试对其执行更多操作它.有没有好的方法来做到这一点?

In my mock, I don't care about the order in which I edit everything on the row, but it's very important that I not try to do anything more to it after I've saved it. Is there a good way to do this?

请注意，我不是在寻找 verifyNoMoreInteractions:它不会确认 saveToDatabase 是最后调用的东西，如果我调用行上没有明确验证的任何内容，它也会失败.我希望能够这样说:

Note that I'm not looking for verifyNoMoreInteractions: it doesn't confirm that saveToDatabase is the last thing called, and it also fails if I call anything on the row that I don't explicitly verify. I'd like to be able to say something like:

verify(row).setSomething(value);
verify(row).setSomethingElse(anotherValue);
verifyTheLastThingCalledOn(row).saveToDatabase();

如果有帮助，我将从执行此操作的 JMock 测试切换到 Mockito:

If it helps, I'm switching to Mockito from a JMock test that did this:

row.expects(once()).method("saveToDatabase").id("save");
row.expects(never()).method(ANYTHING).after("save");

推荐答案

我认为这需要更多的自定义工作.

I think it requires more custom work.

verify(row, new LastCall()).saveToDatabase();

然后

public class LastCall implements VerificationMode {
    public void verify(VerificationData data) {
        List<Invocation> invocations = data.getAllInvocations();
        InvocationMatcher matcher = data.getWanted();
        Invocation invocation = invocations.get(invocations.size() - 1);
        if (!matcher.matches(invocation)) throw new MockitoException("...");
    }
}

上一个答案:

你是对的.verifyNoMoreInteractions 是您所需要的.

You are right. verifyNoMoreInteractions is what you need.

verify(row).setSomething(value);
verify(row).setSomethingElse(anotherValue);
verify(row).editABunchMoreStuff();
verify(row).saveToDatabase();
verifyNoMoreInteractions(row);
