simple patching for python functions
Project description
simple_mock
Introduction
The motivation behind this library is to provide easy way of mocking to python functions while doing the unittest.
This library is based on "mock" module in python
Installation
Install via pip:
$ pip install simple_mock
Install from source:
$ git clone https://github.com/satyavls/simple_mock.git
$ cd simple_mock
$ python setup.py install
Usage
# example - mocking single function to return some value or exception
import unittest
from simple_mock import SimpleMock
# import of function that needs to be patch in test case file
from add_module import add_num
class TestAddNum(unittest.TestCase):
def setUp(self):
# create simple mock object
self.simple_mock = SimpleMock()
def tearDown(self):
self.simple_mock.clear_all_patch()
def test_add_num(self):
"""
This is example where add_num function is patched to return the 45 value
"""
# patch the add_num function to return 45 value
patched_add_func = self.simple_mock.patch_func(func='add_num', exptd_ret_val=45)
self.assertEqual(add_num(2, 2), 45)
def test_add_num_exception(self):
"""
This is exmaple where add_num function is patched to return exception
"""
# Patch the add_num function to return ValueError
patched_add_func = self.simple_mock.patch_func(func='add_num', exptd_err=ValueError,
err_msg="exception raise in add_num")
self.assertRaises(ValueError, add_num)
if __name__ == '__main__':
unittest.main()
