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

[Francois B. <fb...@us...>]

Hi,

Here's my test implementation:
    private final Mock mockNewsIterator =3D new Mock(Iterator.class);
    private final Iterator newsIterator =3D (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.=20
In the mean time, there should be one call to the next() method.

Thanks,

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.
