I've been wondering about that for a while.

So far, I've not been able to find any examples of test architecture that follows those principles online or in my day job.

I've also been too lazy to do a side project and explore a more decoupled and scalable test suite. Maybe I should get off my arse and finally do it.

If you're writing a web application, i've had a reasonably happy time with tests at the controller level, or perhaps right below. You want an interface where values go in and out that correspond to fairly user-level ideas, but which are still tractable for testing.
