[pytest-dev] Running each test in a Vagrant VM?

How do you configure Pytest to create a new Vagrant VM before each test and
destroy it afterwards?

I'm trying to test a sysadmin tool based on Fabric (http://www.fabfile.org/),
and so the tests need a fresh target server in a known state to login to.

I tried implementing a Pytest plugin, similar to the Fabtools project (
but it's unreliable. Each test seems to pass when I run them separately,
but when I run all my tests together, there's some bug that's preventing
the VM from being destroyed and re-created properly, causing many tests to
fail when the previous test leaves the VM in an unexpected state.

Has anyone else implemented similar tests with Pytest?
