unittest

[Zunbeltz Izaola]

Hi,

I am using unittest for the first time. I have read chapter 7 of dive into
pyhton (Unit Test). I have the following code

from spacegroup import *
import pygroups.misc.m atrix as matrix
import unittest

class KnowValues(unit test.TestCase):

KnownRotationMa trices = [
((Rotational3Pa rt([[-1,0,0],[0,1,0],[0,0,-1]])),
(1, -1, 2, matrix.vector([0,1,0])))
]

def TestRotationalP artdeterminant( self):
""" RotationalPart. determinant with known values."""
for i in self.KnownRotat ionMatrices:
det = i[0].determinant()
self.assertEqua l(det,i[1][0])


if __name__ == "__main__":
unittest.main()

but when i run this scrip i get the following output


----------------------------------------------------------------------
Ran 0 tests in 0.000s

OK

Why the test didn't run? any idea?

TIA

Try renaming your test case method "test_rotationa l_partdetermina nt".

Tnaks, why is this so?

Re: unittest

Change your method name to begin with "test" instead of "Test" and it should work.

From the fine manual
(http://www.python.org/doc/current/li...example.html):

A testcase is created by subclassing unittest.TestCa se. The three
individual tests are defined with methods whose names start with
the letters "test". This naming convention informs the test runner
about which methods represent tests.

The convention is necessary because you might want methods that are
*not* tests.

I have to read the manuals at full :-)
