Question: Testing with injector about injector HOT 3 OPEN

from unittest import mock 
def test_start():
    # Given
    mocked_controller = mock.Mock(spec=Controller)
    mocked_controller.get_project_by.return_value = Project("test_project", "test_owner", [], "0")

    mocked_repo = mock.Mock(spec=Repository)
    mocked_repo.start_optimization.return_value = ""

    def configure(binder):
        binder.bind(Controller, to=injector.InstanceProvider(mocked_controller))
        binder.bind(Repository, to=injector.InstanceProvider(mocked_repo))

    injector = Injector(configure)
    subject = SubjectClass(injector=injector)

    # When
    subject.start_optimization() 

    # Then
    mocked_repo.start_optimization.assert_called_once()
    

    def test_start(self):
        subject = SubjectClass();
    
        Injector().get(Controller).get_project_by = Mock(
            return_value=Project("test_project", "test_owner", [], "0"))

       Injector().get(Repository).start_optimization = Mock(return_value="")

       subject.start_optimization() -> calls inside the Injector of Repository

        # The problems happens here
       Injector().get(Repository).start_optimization.assert_called_once()
