Hi,
With AAA, there's no specific API for doing that. In Natural you can use recorder.Repeat, or any of the repeating overloads (like ExpectAndReturn).
The reason we've not done this in AAA, is that we believe that if you need to verify that, your test is over specified. The reason this is not so good, is that because over-specified tests are fragile. Fragile tests break with very small changes inside the production code, and when they do - you need to fix them. You don't want to spend your time maintaining tests.
Hope this helps,
