python mock patch : a method of instance is called?
- by JuanPablo
In python 2.7, I have this function
from slacker import Slacker
def post_message(token, channel, message):
channel = '#{}'.format(channel)
slack = Slacker(token)
slack.chat.post_message(channel, message)
with mock and patch, I can check that the token is used in Slacker class
import unittest
from mock import patch
from slacker_cli import post_message
class TestMessage(unittest.TestCase):
@patch('slacker_cli.Slacker')
def test_post_message_use_token(self, mock_slacker):
token = 'aaa'
channel = 'channel_name'
message = 'message string'
post_message(token, channel, message)
mock_slacker.assert_called_with(token)
how I can check the string use in post_message ?
I try with
mock_slacker.chat.post_message.assert_called_with('#channel')
but I get
AssertionError: Expected call: post_message('#channel')
Not called
