> Kafka to Pub/Sub pipeline [example|https://github.com/apache/beam/pull/13112]
> needs to have e2e tests. However, in Beam Testing Guide
> [https://cwiki.apache.org/confluence/display/BEAM/Contribution+Testing+Guide]
> , we have not found examples or documentation for e2e tests that require a
> Pub/Sub environment can be set up.
> During the investigation and with the help of our reviewers we found possible
> approaches for our issue.
> For Pub/Sub, e2e test could use [Pub/Sub
> emulator|https://cloud.google.com/pubsub/docs/emulator]
> These e2e test examples can be referenced in the
> [https://cwiki.apache.org/confluence/display/BEAM/Contribution+Testing+Guide]
> to serve examples of how customers may approach e2e testing of pipelines in
> their environments.
