Using py.test, two tests called the same in different directory causes py.test to fail. Why is that? How can I change this without renaming all the tests?

To duplicate do:
    
    ; cd /var/tmp/my_test_module
    ; mkdir -p ook/test           
    ; mkdir -p eek/test
    ; touch ook/test/test_proxy.py
    ; touch eek/test/test_proxy.py
    ; py.test
