Hi, When I was working on AIP-47 (new design of system tests) I noticed that Google has tests for coverage of operators with examples. I revived it a bit to also work with new system tests, but I wasn't fully satisfied. I have decided to rewrite it so it can be easily reused by other providers. As a bonus it now has pluggable architecture. Here is PR: https://github.com/apache/airflow/pull/23351
Any provider that wishes to test for the coverage of their examples/system tests or test anything else in the structure of their operators can reuse this code (create their own classes in the file and inherit from base classes). In the case of Google I have created two kinds of tests: example coverage and also extra assets coverage. I also did it for elasticsearch and docker providers to show how it's possible to extend it for other providers. Check out the PR and let me know what you think and if there is room for improvements :) Regards, Bartłomiej Hirsz
