[MO-java-dev] Is it possible to verify call sequence between two or more Mocks ?

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

Hi,

I'm using DynaMocks 0.09 and would like to know if one can check the=
=20
sequence of calls between more than one mock.

For example, I am writing tests for an object that should retry=20
operations once on the object, but must call another one in the mean =
time:

public void method() throws FailureException {
    try {
       obj.operation();
    } catch (FailureException e) {
       obj =3D obj2.factory();
       obj.operation();
    }
}

So, both mocks should cooperate to determine if the correct sequence =
of=20
operations was executed.

Thanks for any tips or pointers.

Bye !

There's a constructor in Mock (for the release) and CoreMock (for the=20
CVS head) that allows you to pass in the collection that gathers=20
expectations. I think you can achieve what you want by making both mock=20
implementations share a common expectation collection.

We have some ideas about how to specify precedence but we have to do=20
some more clean-up first.

Yes, but with a bit of effort.  The trick is to create a Callable decorator
that matches a method invocation only when it is called in the correct
order. I've attached a test and support classes that implement this which
should make things more clear.  We are currently working on providing more
convenient support for sequences across multiple mocks in the next version
of the dynamic mocks.

Cheers,
            Nat.
