It is intended if you read the docstring (I totally missed it too, at
first). If level is negative, then it is equivalent to returning all the
test corresponding to abs(level) in a test suite, without running them.
As I do not want to run the tests, just the testsuite, I passed level
-10 (which is supposed to return all the tests at all level, if I
understand correctly). I agree this is not really intuitive.

Are you aware of set_local_path ? I used it when I need to use the same
function/global variables accross several test files. You can see an
example in the learn scikits (scikits/learn/machine/em/test_densities).
# import modules that are located in the same directory as this file.
from testcommon import DEF_DEC
This is basically a hack to put the current path (or any other relative
path you give to set_local_path function) in sys.path so that they are
found by the python interpreter.
