Exactly.

Once per session would be actually sufficient for this specific case
today, but the need is once per test directory.

To be a bit more explicit, in my current software development, I have
both unit tests for functionality in App1 that I develop myself, and
functional tests for a wrapper around App2, which is an external
application :

base
+ app1
    + tests
        + many unit tests
+ app2_wrapper
    + external_app2
    + tests
        + many functional tests for the app2 wrapper, requiring to setup

          a resource for app2 to run.

I launch py.test from the base directory.

I have an expensive setup/teardown for the functional tests of the app2
wrapper, which I would like to share at the app2_wrapper/tests directory
level.

Ideally, if I run only tests from app1, I don't run that expensive
setup/teardown.

cheers,

Philippe
