How To Locally Unit Test Python 3 App Engine Application?

I have testbed setup locally to test python2.7 based app engine application. As part of the python3 migration activity, I am wondering how do I setup the app engine testbed. It see

Solution 1:

I couldn't find any relevant doc for the new AppEngine 3 environment and the testbed package. According to the documentation in the python docs for AppEngine the testbed package doesn't belong more to the python 3 official libraries for AppEngine.

You can read the content of the package here:

Maybe if you isolate your unit tests in a acceptable level, you can exclude the remote resources.
