Test failure with .helpers import AsyncMock

[phls]

Hi, I'm building debian package with the last version, but my tests are failing.

======================================================================
ERROR: test_namespace (unittest.loader._FailedTest.test_namespace)

ImportError: Failed to import test module: test_namespace

It seems because of: .helpers import AsyncMock, _run

But I couldn't find this module anywhere.

How can I fix that?

Thanks,

The module is here.

I suggest you use tox to run the tests, or look at the tox configuration to learn how to create an environment that is proper for the tests. I'm not sure exactly what your mistake is, but something is wrong in your setup.
