Testing with Injector¶
When you use unit test framework such as unittest2 or nose you can also profit from injector. However, manually creating injectors and test classes can be quite annoying. There is, however, with_injector method decorator which has parameters just as Injector construtor and installes configured injector into class instance on the time of method call:
import unittest from injector import Module, with_injector, inject class UsernameModule(Module): def configure(self, binder): binder.bind(str, 'Maria') class TestSomethingClass(unittest.TestCase): @with_injector(UsernameModule()) def setUp(self): pass @inject def test_username(self, username: str): self.assertEqual(username, 'Maria')
After such call all
inject()-decorated methods will work just as you’d expect them to work.
