Hi Jo,

I invited you to join. It looks like Slack invite links expire after a couple 
days, so the one you were using may be out of date.

Hi, currently I'm joining the Beam Summit 2021 and would like to learn more by 
joining the Beam Slack Channel. But it seems I can't join with my personal 
email and I don't have the @apache.org email either. I would 
like to ask if I can get invited to the Slack channel, or maybe there is 
another way to join? Thanks! Regards

How to test ReadFromPubSub

[Bergmeier, Andreas]

We have a PTransform, which uses ReadFromPubSub and now would like to test it.
Looking at 
https://github.com/apache/beam/blob/master/sdks/python/apache_beam/io/gcp/pubsub_test.py
 it seems like we would need something similar to TestReadFromPubSub.
I do however not understand how this works at all since e.g. there seems to 
appear a mock_pubsub out of thin air.
Can someone please give a rough sketch which parts need to work together how in 
order to test ReadFromPubSub in a TestPipeline?
