Pattern for testing raw dumps

test_barrier_reply.py

import unittest

from pyof.v0x01.controller2switch.barrier_reply import BarrierReply
from tests.rawdump import RawDump


class TestBarrierReply(unittest.TestCase):
    def setUp(self):
        self.message = BarrierReply(xid=5)
        self.raw_file = RawDump('v0x01').read('ofpt_barrier_reply')

    def test_get_size(self):
        self.assertEqual(self.message.get_size(), 8)

    def test_pack(self):
        raw_obj = self.message.pack()
        self.assertEqual(raw_obj, self.raw_file)

    def test_unpack(self):
        unpacked = BarrierReply()
        unpacked.unpack(self.raw_file)
        self.assertEqual(unpacked, self.message)
