jMock-允许()多次调用不同的结果 [英] jMock - allowing() a call multiple times with different results

问题描述

我想多次拨打allowing()并提供不同的结果.但是我发现第一个allowing()规范吸收了所有调用，并且无法更改返回值.

I want to call allowing() several times and provide different results. But I'm finding that the first allowing() specification absorbs all the calls and I can't change the return value.

@Test
public void example() {
    timeNow(100);
    // do something

    timeNow(105);
    // do something else
}

private void timeNow(final long timeNow) {
    context.checking(new Expectations() {{
        allowing(clock).timeNow(); will(returnValue(timeNow));
    }});
}

如果我将allowing(clock)更改为oneOf(clock)，则可以正常工作.但理想情况下，我想使用allowing()而不是过度指定时钟仅被调用一次.有什么办法吗?

If I change allowing(clock) to oneOf(clock) it works fine. But ideally I want to use allowing() and not over-specify that the clock is called only once. Is there any way to do it?

推荐答案

我建议您看一下状态-它们使您可以根据测试所处的状态"来更改要使用的期望.

I would recommend taking a look at states - they allow you to change which expectation to use based on what "state" the test is in.

@Auto private States clockState;
@Test
public void example() {
    clockState.startsAs("first");
    timeNow(100);
    // do something

    clockState.become("second");
    timeNow(105);
    // do something else
}

private void timeNow(final long timeNow) {
    context.checking(new Expectations() {{
        allowing(clock).timeNow(); will(returnValue(timeNow));
        when(clockState.is("first"));

        allowing(clock).timeNow(); will(returnValue(timeNow + 100));
        when(clockState.is("second"));
    }});
}
