Python Nosetest - How to mock MySQLdb

I'm trying to mock the MySQLdb lib from my project but I don't really understood how to do it:

Here's my test code:

import unittest from mock import MagicMock from core.distrib.main.CentralDistDraw import CentralDistDraw from connector.mysql import MySQL class CentralDistDraw(unittest.TestCase): def test_hello(self): draw = CentralDistDraw() msql = MySQL() msql.getConnection = MagicMock() 

Here's my class:

from datetime import datetime import logging from core.distrib.config.PromoConstants import PromoConstants from dateutil.parser import parse from google.appengine.api import memcache from connector.mysql import MySQL from core.distrib.ndb.userpromo import UserPromo from core.distrib.ndb.drawinfo import DrawInfo import traceback class CentralDistDraw(object): def getNextNumber(self, idUser, amountDefault=1, amountSpecial=1): numbersDelivered = [] # DB CONTROLL.... db = MySQL().getConnection() db.autocommit(False) currentUser = None 

Error thrown:

ERROR: Failure: ImportError (/home/dyego/Documents/code-stuff/mod/pdbcontest2/src/lib/_mysql.so: invalid ELF header) ---------------------------------------------------------------------- Traceback (most recent call last): File "/usr/local/lib/python2.7/dist-packages/nose-1.3.7-py2.7.egg/nose/loader.py", line 418, in loadTestsFromName addr.filename, addr.module) File "/usr/local/lib/python2.7/dist-packages/nose-1.3.7-py2.7.egg/nose/importer.py", line 47, in importFromPath return self.importFromDir(dir_path, fqname) File "/usr/local/lib/python2.7/dist-packages/nose-1.3.7-py2.7.egg/nose/importer.py", line 94, in importFromDir mod = load_module(part_fqname, fh, filename, desc) File "/home/dyego/Documents/code-stuff/mod/pdbcontest2/src/tests/core/test_central_dist_draw.py", line 4, in <module> from core.distrib.main.CentralDistDraw import CentralDistDraw File "/home/dyego/Documents/code-stuff/mod/pdbcontest2/src/core/distrib/main/CentralDistDraw.py", line 11, in <module> from connector.mysql import MySQL File "/home/dyego/Documents/code-stuff/mod/pdbcontest2/src/connector/mysql.py", line 8, in <module> import MySQLdb File "/usr/lib/python2.7/dist-packages/MySQLdb/__init__.py", line 19, in <module> import _mysql ImportError: /home/dyego/Documents/code-stuff/mod/pdbcontest2/src/lib/_mysql.so: invalid ELF header ---------------------------------------------------------------------- Ran 1 test in 0.001s FAILED (errors=1) 

Anyone knows the correct way to go when comes to testing third party libraries?

Thanks!
