Last week, we had the author of TDD for a Shopping Website LiveProject. Friday at 11am Ranch time, Steven Solomon will be hosting a live TDD session just for us. See for the agenda and registration link
For Part 2, if my assignment's business domain model shows some business entities that never appear in any of the use case specifications, do I need to add this kind of business entities to my class, component and sequence diagrams?
For example, if the business domain model has a "Payment" class, but "Payment" is not mentioned in any of the use case specifications, do I need to do anything with "Payment" for my diagrams?
