Counting backwards (as we appear to be writing the book in reverse), the next chapter - Chapter 8, Acceptance Testing - is now up on the Apress Alpha Books page.
We've divided acceptance testing into two areas - business requirements (the subject of Chapter 8), and behavioral requirements (the subject of Chapter 7, which we've just completed and should be up on the Alpha Books page soon).
So Chapter 8 is really Acceptance Testing Part II (or Part I, depending which way around you look at it...)
We think QA testing teams should be very happy with Chapter 8, as it demonstrates an automated method of turning business requirements into test reports and checklists. The chapter shows how to generate customer-facing (and tester-facing) business requirement tests from the requirements in your analysis model, how to organise those tests, and how to generate a test plan document from them. This process supports an independent Quality Assurance organisation, providing a level of assurance that the customer's requirements have been met, beyond the development team asserting that "all our unit tests light up green."
