Discussion:
This Issue replace Watch events may be missed and the test may still pass. We need to ensure that all expected watch events are seen. Watch events are not collected and checked at the end of the test. In order to solve the problem, we must collect all watch events as they come in and perform a check at the end of the test to ensure that the order is correct and they contain no errors.

AI: Must allow for other events to occur through the expected watch events stream expected watch events: must allow the following to be valid:
[x] Set up a watch for resource through a static label to the resource with DynamicClient [x] Manage the watch if it dies [x] Feed the watch to the function [x] Read all the watch events from the at the end of the test, ensuring that the events occur question: What does doing this mean to tests which check data? (e.g: - waits for values, sourced from watch) [x] Retry the test, upon failure [x] Manage the resources on retry (delete)
More or less, yes. If we need to read results mid-test, I think that will be OK, rather than waiting for the end. The main point is to wrap the watch such that it gets restarted if it fails. That wrapper will need to sit between the raw watch channel and the test: raw watch -channel -wrapper (restarts watch if closes/fails prematurely) -channel consumed in test I'm a little surprised there isn't already a sort of "buffered watch" object that does this already ? You'll also need a stop channel for the go routine started by the wrapper, so that at the end of the test you can stop that go routine and watch.
Also, if we have the "protected watch" wrapper, not sure we need to retry the test on failure. AFAIU, the only reason we wouldn't see the watch events we expected would be because of etcd compaction, which would not be expected to happen in e2e clusters, and even if it did it would not happen to event histories that are brand new (i.e., it only compacts old history). Again would like to confirm.

[x] Original approval issue: Start 9 June 2020 3 Flakes No Flakes for 2 weeks According to this APIsnoop query, there are still some remaining ReplicationController endpoints which are untested. a ReplicationController with a static label the ReplicationController with a new Label and updated data the ReplicationController's status /Scale the ReplicationController's Replica count to 2 Replicas the ReplicationController the ReplicationController's Status all ReplicationControllers in all Namespaces find the ReplicationControllers(1) ensure that the ReplicationController is found and is patched Namespaced ReplicationControllers(1) via a Collection with a LabelSelector Discover useragents: See all endpoints hit from this test Display test coverage change If a test with these calls gets merged, test coverage will go up by 7 points This test is also created with the goal of conformance promotion.
