Test data processor

Skoro i tak tworzymy Mocka, to można wywalić ten cały kram.
Można to zrobić chociażby tak:
<code>
    def setUp(self):
        self.patcher = mock.patch("deltacompression.backend."
                                  "directory_processor.DirectoryProcessor",
                                  autospec=True)
        self.addCleanup(self.patcher.stop)
        self._mock = self.patcher.start()
        self._dir_mock = self._mock.return_value
        self._version_processor = versions_processor.VersionsProcessor(
            self._dir_mock)
</code>
