Discussion:
According to this APIsnoop query, there are still some remaining Endpoints endpoints which are untested. Create a Service in a namespace List all Endpoints in all Namespaces find the created Service(1) Replace/update the Namespaced Endpoint for the Service(1) Patch the Namespaced Endpoint for the Service(1) Get the Namespaced Endpoint for the Service(1) Delete Namespaced Endpoint(1) via a Collection with a LabelSelector Discover useragents: If a test with these calls gets merged, Conformance coverage will go up by 4 points /sig testing /sig architecture /area conformance
When you create a selector, race conditions can occur between controllers and our test code. We have services that test endpoint code, we could do these as explicit tests that are NOT handled by the endpoints controller. Let's try this with are managed by the endpoints controller w/ a selector. Endpoints normally go along with services: we want to create a service sans selector. This keeps it out of the endpoints controller, so we can test directly. Agreed for backlog. Double check that we don't already have test for that, whether it's being done by the endpoints controller that doesn't hit the API. Look at ALL the user agents that hit the endpoint.
