Hi,

Why are you passing the requests (with typo ?) module to the function ? anyway, the code could look like this:

!! untested code, I don't have the requests module installed !!

import requests
import mock

def myView():
	res1 = requests.get('aurl')
	res2 = requests.get('burl')
	res3 = requests.get('curl')

@mock.patch('requests.get', mock.Mock(side_effect = lambda k:{'aurl': 'a response', 'burl' : 'b response'}.get(k, 'unhandled request %s'%k)))
def testMyView(mockedGet):
	# you can further customize the mock object here
	mockedGet.whatever()
	myView()

testMyView()


side_effect is the mock way of returning multiple values.

Hope it helps,

JM
