Mock

[Olegt0rr]

Hi there!
What about unittest.mock in asyncio?

To be honest I left this issue due to lack of my understanding, sorry. A mock object cooperates perfectly with a futurized and can be used to mock/patch coroutines. Additionally in the meantime I've added helper - to mock async iterators.

I bumped into this today and I managed to get it working like this:

class MyTest(unittest.TestCase):
  @mock('myfunction')
  @async_test
  async def test_myfunc(self, mock):
    mock.return_value = futurized(42)
    result = await myfunction()
    self.assertEqual(result, 42)

The key is to have the mock's return_value and/or side_effect to return futurized values.

When using the async_test decorator ensure that it is the closest decorator to the test function.

Hope this helps.
