ok, i've written a couple of unit tests and it was pretty straight forward as far as what i should and shouldn't be testing in the unit test.. until now.
i am testing a customer model right now.. i figure that a unit test should test the functions of a model as well as if you can do all the crud stuff and validations. right now i wish to test a customer model function that returns what level of customer they are.. this is based on what things they've ordered in the past. so my question: is it ok to bring in other models when doing unit tests? i figure i will have to load at least 3 other test fixtures to test this out (orders, order_items, and inventory), but not even sure if i can actually use the other models in the customer unit test because i tried putting test = Order.new in my test and it failed on that line.. i'm starting to think that maybe this aspect shouldn't be tested in the unit test?
thanks in advance
