[x] Original approval issue: - Reverted due to flakes [x] Two weeks soak end date: 20 November 2020 This issue is created to allow edit by /wip /hold According to this APIsnoop query, there are still some remaining Pod endpoints which are untested. a Pod with a static label the Pod with a new Label and updated data the Pod to ensure it's patched the Pod's status the Pod's status Ready condition to False the Pod's status to check if Ready is False all Pods in all Namespaces find the Pod(1) ensure that the Pod is found and is patched Namespaced Pod(1) via a Collection with a LabelSelector the Pod to check that it's deleted Discover useragents: List endpoints hit by the test: Display endpoint coverage change: If a test with these calls gets merged, test coverage will go up by 4 points This test is also created with the goal of conformance promotion. /sig testing /sig architecture /area conformance
