I've just spent close to 4 months going through the mill with my development group over what they will do and what I would like them to include in a Unit test document. This is what we came up with. Maybe it can help you as a starting point.
We don't really encourage people to use ready-made templates at least for core testing purposes. Reasons are that templates are usually contextual, drawn in specifics to the requirements of that particular organization, and mainly because it limits your view of testing resulting in loss of innovation.
However its is not that none of us have never used templates. if you could be a little more specific and tell us as to what kind of templates you want, how do you wish to use them, meaning are you going to evolve or generate some of your own from the them or use them as is, then maybe some of us could help you more.
But if it is the case that you need a pick-n-place kinda thing then please refrain from doing so.
