How to use the zopfli.gzip function in zopfli

data = unittest.__doc__

        data = self.data 
        self.assertEquals(self.decompress(self.compress(data)), data)

        data = self.data
        self.assertTrue(len(self.compress(data, numiterations=1)) > len(self.compress(data, numiterations=1000)))

class ZlibTest(unittest.TestCase, Tests):
    compress = staticmethod(zopfli.zlib.compress)
    decompress = staticmethod(zlib.decompress)

class GzipTest(unittest.TestCase, Tests):

    compress = staticmethod(zopfli.gzip.compress)
    
    def decompress(self, s):
        return gzip.GzipFile(fileobj=StringIO.StringIO(s)).read()
