Pierre,

I believe if you rename your TimingTests they'll work.  Nose looks for
functions starting with "test", and runs those.  So your 'utility' functions
like testta, testtb... should not begin with "test", but the function
calling them, timingTest, should.  Probably want to use more meaningful
names than my hack though.  :)

def test_timingTest():
    for f in [testf, testinplace]:
        for n in [1000,10000,50000]:
            t = func_ta(n, f)
            t1 = testtb(n, f)
            t2 = testtc(n, f)
            print f.test_name
            print """\
n = %7d
numpy time (ms) %6.1f
MA maskless ratio %6.1f
MA masked ratio %6.1f
""" % (n, t*1000.0, t1/t, t2/t)

def func_ta(n, f):
    x=numpy.arange(n) + 1.0
    tn0 = time.time()
    z = f(x)
    return time.time() - tn0

Then to run only test_timingTest:

cburns@tests 21:30:19 $ pwd
/Users/cburns/src/numpy-trunk/numpy/ma/tests

cburns@tests 21:33:13 $ nosetests -sv test_old_ma:test_timingTest
test_old_ma.test_timingTest ... Simple arithmetic
n =    1000
numpy time (ms)    1.9
MA maskless ratio   14.9
MA masked ratio   18.4

Ran 1 test in 2.912s

OK
