Andrei,

I've personally thought about this some time ago.  Right now, Avocado
tries to "isolate" tests from each other by using separate processes.
This is a rather weak isolation, but still better than what many other
test runners offer.

I believe that having stronger isolation at a test level would indeed be
really useful.  Running each test on a separate and disposable
"execution environment" (container, vm with snapshot, physical machine
that gets reloaded) would be really powerful.

Still, we don't have that feature at this time...

... and it doesn't exclude the careful writing of tests as a good practice.
