Integration Tests

• The RabbitMQ "service" container that we use currently can not start up with our custom config and SSL certificates required in integration tests: st2common/tests/integration/test_rabbitmq_ssl_listener.py
  • To "fix" this we need to install/config/run RabbitMQ ourselves, but getting this working in GHA has proven to be difficult (unable to install rabbitqmq-server apt package successfully)
• Ran into issues with the python_action_process_wrapper tests (contrib/runners/python_runner/tests/integration/test_python_action_process_wrapper.py).
  • The specific test that is failing is: (test_stdin_params_timeout_no_stdin_data_provided)[https://github.com/StackStorm/st2/blob/master/contrib/runners/python_runner/tests/integration/test_python_action_process_wrapper.py#L127-L139]
  • It is failing because inside of python_action_wrapper.py it is always receiving an empty string on stdin rather than blocking on input and timing out here: https://github.com/StackStorm/st2/blob/master/contrib/runners/python_runner/python_runner/python_action_wrapper.py#L305-L315

@winem Can you push this PR to completion, or at least partial completion? If we only offload four of the five TASKs to GitHub Actions, that's will still be very useful for us. Travis CI latencies are terrible, so we still gain something even if we don't completely move off of their platform entirely.

[winem]

@blag yes, I'll tackle the rabbitmq issue.

Thanks @winem.

Quick context:

Per discussion, the transient agreement was to move the Unit tests to Github Actions,
while keeping the Integration Tests in TravisCI. The RabbitMQ (Integration Tests) issue could be postponed that way.

That would already help a lot.

To merge this PR we need to make sure:

• Unit Tests + Checks are running in GH Actions (done)
• Unit Tests in GH Actions are green: 90% done
• Only Integration Tests are running in TravisCI (done)
• Integration Tests in TravisCI are green (as before)

@armab I don't see any failing unit tests when I take a look at https://github.com/StackStorm/st2/runs/1704636828?check_suite_focus=true for example. All the exceptions that are shown are expected and the tests as such pass.

Please enlighten me. Looks like I miss something here. I'm happy to tackle remaining tests over the weekend.

That was a great team effort @nmaludy @blag @winem! 👍
Really happy to see this merged and part of our tests running in GH Actions.
