如何将参数传递给mockito中的返回方法 [英] How to pass argument to return method in mockito

问题描述

我想传递我模拟的方法的参数以返回值

I would like to pass argument of method I mock to return value

示例:

when(mockedObject.printEntries(anyLong()).thenReturn("%d entries");

有没有办法做到这一点?

Is there a way to achieve that?

推荐答案

您必须利用 thenAnswer 功能:

Answer<String> answer = new Answer<String>() {
    public String answer(InvocationOnMock invocation) throws Throwable {
        Long long = invocation.getArgumentAt(0, Long.class);
        return long + " entries";
    }
};


when(mockedObject.printEntries(anyLong()).thenAnswer(answer);
