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:

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

I'm trying to use flask-ask library and develope a skill that can make me able to control a robot in ROS with alexa vocal assistant. Python code named "alexa_interface.py" is here.
The skill id number is substituted with my skill id number.
While launching this command
python3 alexa_interface.py
I am getting the following code error.
Tried to install dependencies with pip but getting:
AttributeError: module 'lib' has no attribute 'ERR_load_RAND_strings'
Also notice that I am getting this error everytime I use pip to install something. Is pip broken? How can I adjust this?
Thank you.

I am new to Python 3.4.5 which I am learning online by watching videos with some good knowledge of C. I am trying to download an image via Python which I am unable to do because of this error.

urllib.request.urlretrieve(url,full)

Try:
def img(url): full='name'+'.jpeg';urllib.urlretrieve(url,full)
urllib.request does not exist in Python 2.x, which seems to be your case
so don't try to import that in second line of your code
plus you made a typo (forgot semicolon) which works as a statement separator while writing inline function statements.
Similar to:
def img(url):
full='name'+'.jpeg'
urllib.urlretrieve(url,full)

Thanks in advance for your help !
You shouldn't normally need a models.py in your tests directory.
If you want to import your Entreprise model from the front app, then change your import from
from .models import Entreprise
to
from front.models import Entreprise
I have some code that looks like this
try:
import calvin.reasoning.rule_list
except:
print "rule_list exception"
And I have commented out every import statement in rule_list.py, so it looks like this
#import quantities
#import rules
#from conclusions import Conclusion
#from conclusions import Data
#from confidence import Validity
If I delete the contents of rule_list my program runs, but why would python throw an exception if there is not a circular import?
Here is the traceback

Has anyone else encountered the situation where they have written unit tests for their code into a file named unittest.py, and found it to conflict with NumPy's unittest.py module? In other words, if I write this to unittest.py in a local directory:
if __name__ == "__main__":
print "pre-import"
#import numpy
print "post-import"
Then (no surprises here):
% python unittest.py
pre-import
post-import
But if I do:
if __name__ == "__main__":
print "pre-import"
import numpy
print "post-import"
I get:
% python unittest.py
pre-import

or send an email to the mailing list at ipython-dev#scipy.org
You can print a more detailed traceback right now with "%tb", or use "%debug"
to interactively debug it.
Extra-detailed tracebacks for bug-reporting purposes can be enabled via:

Of course it is trivial to change the name of the file containing my unit tests and avoid this, but I wonder if anyone else encountered this and thought of an elegant workaround that doesn't include renaming their unit test file?
You can switch to absolute imports by default on Python versions newer than 2.7:
from __future__ import absolute_import
if __name__ == "__main__":
print "pre-import"
import numpy
print "post-import"
