I have a very easy test:
from unittest.mock import Mock
from urbansearch import main
main.ArgumentParser = Mock()
def test_parse_arguments():
main.parse_arguments()
main.ArgumentParser.add_argument.assert_called()
which tests the following method:
from argparse import ArgumentParser
def parse_arguments():
parser = ArgumentParser(description='The TU Delft Urbansearch CLI')
parser.add_argument('-d', '--directory',
help='Source files directory containing files with '
+ 'indices')
return parser.parse_args()
when testing this I get the error: AttributeError: assert_called. Why do I get this error and how do I solve this? I have also tried many different variations but I always get more or less the same result.
edit: The test is located in Urbansearch/tests/test_main.py. The method is located in Urbansearch/urbansearch/main.py.
The exact output I get is the following;

You're using Python 3.5 and the method assert_called
is new in Python 3.6.
