AshishNaware commented 1 month ago

This PR adds ability to install watch reaction function to the fake client. This will help in writing tests where its required to simulate behavior of the watcher.

Hi @AshishNaware. Thanks for the contribution. This change is heading in the right direction, but is also incomplete as it has no runtime effect. WithWatchReactors needs to be plumbed into the test cases (ReconcilerTestCase/SubReconcilerTestCase/AdmissionWebhookTestCase) the same way WithReactors is. That part is relatively simple. The more complicated part will be consuming the WatchReactionFunc. The client wrapper doesn't currently implement Watch that method will need to be implemented and consume the reaction funcs. The DuckAwareClientWrapper also needs to have Watch added.

Let me know if you need any pointers into the code base.

Hey. Thanks for the feedback. Let me dig more into the code-base. I will create a thread here if i have any questions :)

@scothis - I just took a quick glance at the code and I see a Watch method already implemented for duckAwareClientWrapper that returns a watch.Interface. I assume that we need a similar implementation for the clientWrapper as well. thoughts?

Yep. This is also where the watch reaction funcs should be applied.
