Organising unit tests

[jimburton]

I have a number of unit tests organised hierarchically, all of which
inherit fixtures from a base class. To run these all at once I started
out using

from basic import map, directionalpan, layerorder, layervisibility,
listlayers, streamlayerlist
# ... lots more ...

suite0 =
unittest.TestLoader().loadTestsFromTestCase(direct ionalpan.TestPan)
suite1 =
unittest.TestLoader().loadTestsFromTestCase(layero rder.TestLayerorder)
# ... lots more ...

alltests = unittest.TestSuite([suite0
, suite1
....])
unittest.TextTestRunner(verbosity=2).run(alltests)

Which is unmaintainable. the TestLoader docs warn that
loadTestsFromModule will not play nicely with my situation and indeed
if I try

suite0 = unittest.TestLoader().loadTestsFromModule(basic)

then run the tests, it hasn't picked any up. I suppose I could collect
and run the tests with a shell script...what are my options here to
avoid hardcoding and maintaining the list of tests, and how is it
normally done?

Thanks.

OK, so I'm trying to collect the tests with python and add them to the
test suite dynamically, but I have a problem with module names. Here's
what I've got:
#########################
import os
from os.path import join
import unittest

alltests = unittest.TestSuite()

def mightBeATest(f):
#TODO check whether it really is a test
return f.endswith('.py') and f != '__init__.py'

def isModule(d):
if not os.path.isdir(d):
return False
for f in os.listdir(d):
if f == '__init__.py':
return True
return False
def getTestsFromDir(dir, currentmod):
for f in os.listdir(dir):
if not f.startswith('.'):
if isModule(f):
#TODO how to check whether we are several modules in?
mod = __import__(f)
getTestsFromDir(os.path.join(dir, f), mod)
elif mightBeATest(os.path.join(dir, f)):
fname, etx = os.path.splitext(f)
print 'adding test
with',('alltests.addTests(unittest.TestLoader().lo adTestsFromTestCase('+(currentmod.__dict__[fname])+'))')

eval('alltests.addTests(unittest.TestLoader().load TestsFromTestCase('+currentmod.__dict__[fname]+'))')
getTestsFromDir(os.curdir, None)
print alltests.countTestCases()
############################

it's importing and referring to the current module that I have a
problem with...it gives me a key error.
