spurious reset before tests

The following test script shows a spurious reset. It is due to the resource being always dirty, and getResource called from the test case. I'm not sure how to fix this, and it should be relatively cheap - if folk are overriding reset its because they can tune it.

import unittest

import testresources

resource_value = object()

class Resource(testresources.TestResource):

    def make(self, dependency_resources):

        print "Making resource"

        return resource_value

    def reset(self, old_resource, result=None):

        print "Resetting resource"

        assert old_resource is resource_value

        return resource_value

    def clean(self, resource):

        print "Cleaning resource"

        assert resource is resource_value

    # This doesn't seem to work.

    def isDirty(self):

        return True

some_resource = Resource()

class ResetTests(testresources.ResourcedTestCase):

    resources = [('foo', some_resource)]

    def test_one(self):

        print "Test one"

    def test_two(self):

        print "Test two"

def suite():

    result = testresources.TestLoader().loadTestsFromName(__name__)

    return result

if __name__ == '__main__':

    unittest.main(defaultTest='suite')
