This needs to be:
if org_1.fitness > 0 : break

Also, when looping the test, I occasionally get
Test not getting an organism already in the new population. ... FAIL
Test basic selection on a small population. ... ok

======================================================================
FAIL: Test not getting an organism already in the new population.
----------------------------------------------------------------------
Traceback (most recent call last):
  File "test_GASelection.py", line 130, in t_no_retrive_organism
    assert new_org != org, "Got organism already in the new population."
AssertionError: Got organism already in the new population.

I'll try to look at it tomorrow.

PS thanks for fixing test_GAQueens.py as I have not got it error even 
running it 10000 times.
