This is great! Thank you! For the build tests, it looks like the issue is: So, we should handle the error value instead of ignoring it. For the integration test failure, looks like the issue has something to do with the serviceAccountName permissions: The e2e test creates its own ServiceAccount and Roles and uses that in the EventListener that the test creates. Currently, that role only has access to "get" triggers, bindings etc. With this change, it also needs access to "list" these resources: https://github.com/tektoncd/triggers/blob/master/test/eventlistener_test.go#L244 |

Since we are creating cluster-scoped resources, we should also delete them in a cleanup function. (By default we delete the namespace which deletes all the namespaced resources but not the cluster ones).
(e.g. we have a cleanup https://github.com/tektoncd/triggers/blob/master/test/eventlistener_test.go#L608 that is then called in the test: https://github.com/tektoncd/triggers/blob/master/test/eventlistener_test.go#L127)

Got it. Besides, I'm curious about https://github.com/tektoncd/triggers/blob/master/test/eventlistener_test.go#L608. I would like to know why we need to delete eventlistener after the whole namespace is already deleted. It seems that the eventlistener lives along with the namespace.

hmm, that's a good question 🤔
We probably should just delete the EL first and then the namespace? Or just the namespace.

So, if TEST_KEEP_NAMESPACES env var is set, we will not delete the namespace but will delete the EL and the servcie . I wonder if this is intentional behavior.

Thanks for the explanation. It makes sense. Should I also delete the eventlistener in test/eventlistener_scale_test.go after tear down the namespace? I can open another PR.

Actually, maybe we can just remove the lines that delete the EventListener and instead rely on the cleanup that already deletes the namespace to clean it up (in TestEventListenerCreate)?
This commit closes tektoncd#797. This PR uses Listers to get resources in the Eventlistener Sink, rather than directly making calls to the API server. Currently, multiple informers need to be setup when creating a Sink object. But the Sink in the cmd/triggerrun still makes the direct API calls because it only makes the call once when executed, which means Lister cache is not useful in this case. All examples work under this change.

Changes
This PR uses Listers to fetch data from EventListeners, Triggers, TriggerBindings, TriggerTemplates, and
ClusterTriggerBindings, rather than directly making calls to the API server. Currently, multiple informers need to be
specified when creating a Sink object.
All Triggers in examples/ work under this change.
