Re: [MO-java-dev] expectAndReturn does not behave the same as in 0.09 ?

[Nat P. <nat...@b1...>]

If you want to mock the behaviour of a *sequence* of calls to a Mock you
should have used an OrderedMock (or a CallSequence that you add to a normal
Mock), in both v0.09 and the current CVS version.  The fact that your tests
passed in 0.09 sounds like a lucky outcome of the internal implementation
rather than documented/tested behaviour of the API itself.

Warning: don't rely on the current CVS version being stable.  The dynamic
API is still being worked out by the mockobjects team.

Cheers,
            Nat.

Hi,

Here's my test implementation:
    private final Mock mockNewsIterator = new Mock(Iterator.class);
    private final Iterator newsIterator = (Iterator)
    mockNewsIterator.proxy();

    public void
    testInstructsTheCallerToPrintTheBodyAgainWhenMoreItemsRemain() throws
    JspException {
        mockNewsIterator.expectAndReturn("hasNext", C.NO_ARGS,
        Boolean.TRUE);
        mockNewsIterator.expectAndReturn("next", C.NO_ARGS, new
        NewsItem());
        mockNewsIterator.expectAndReturn("hasNext", C.NO_ARGS,
        Boolean.FALSE);

        assertEquals(TagSupport.EVAL_BODY_AGAIN, tag.doAfterBody());
        assertEquals(TagSupport.SKIP_BODY, tag.doAfterBody());

        mockNewsIterator.verify();
    }

When I had 0.09 installed, this test was not failing.  Now, I have
0.10dev (CVS pserver as of 2003/08/26 ~ 15:30), and the test fails.

Does this mean that I should switch to using OrderedMock for such tests ?
 What I am trying to achieve here is to have the mockIterator return true
once, and false once.  If it is called any more times, it should fail.
In the mean time, there should be one call to the next() method.

Thanks,
