问题
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));
}});
}
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?
回答1:
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"));
}});
}
