[Numpy-discussion] problem with NumPy test harness in 1.1.0?

Hi,
Our code depends on NumPy and we have been taking advantage of the  
NumPy test harness
to create test scripts for new features as we develop them. As  
recently as version 1.1.0.dev5064
we had no problem running our tests from the directory in which they  
live, e.g.:

python test_script.py

.....<much output>

.
----------------------------------------------------------------------
Ran 10 tests in 0.397s

OK

However, with the released version NumPy 1.1.0 none of our tests work  
any longer and instead we get this
error message:

Traceback (most recent call last):
   File "test_mfio.py", line 426, in <module>
     NumpyTest().run()
   File "/usr/local/lib/python2.5/site-packages/numpy/testing/ 
numpytest.py", line 655, in run
     testcase_pattern=options.testcase_pattern)
   File "/usr/local/lib/python2.5/site-packages/numpy/testing/ 
numpytest.py", line 575, in test
     level, verbosity)
   File "/usr/local/lib/python2.5/site-packages/numpy/testing/ 
numpytest.py", line 453, in _test_suite_from_all_tests

   File "/usr/local/lib/python2.5/site-packages/numpy/testing/ 
numpytest.py", line 681, in importall
     for subpackage_name in os.listdir(package_dir):
OSError: [Errno 2] No such file or directory: ''

Looking through the archives I have found a reference to the same  
error at
http://www.nabble.com/NumpyTest-problem-td17603890.html.

However, this thread is focused on the use of NumpyTest for test  
scripts within the NumPy source tree and the suggestions
do not seem to apply to our situation.

My question is whether using NumpyTest for our own tests is   
considered to be a proper application of the test module.
If not why not?

If it is, is there some modification we can make to our tests to make  
them work with NumpyTest as it is now configured?
Or is this possibly a bug in NumPyTest?
