Hi Chris,

you can just do what the terminal plugin does

the pytest_collection_finish(session) hook can access session.items

session.items is are the actual tests (i.e. the leaves of the collection 
tree)

note that for finding cases where collection fails you will also need 
the pytest_collectreport(report) hook


if you use pytest.main you can just pass in a object with methods that 
follow the call signatures i have (can be a module or a instance)
