Testing with Injector

When you use unit test framework such as unittest2 or nose you can also profit from injector.

import unittest
from injector import Injector, Module


class UsernameModule(Module):
    def configure(self, binder):
        binder.bind(str, 'Maria')


class TestSomethingClass(unittest.TestCase):

    def setUp(self):
        self.__injector = Injector(UsernameModule())

    def test_username(self):
        username = self.__injector.get(str)
        self.assertEqual(username, 'Maria')
