@jennybuckley It's reasonable to add these tests to the conformance suite, since the functionality is now GA. However, the tests need names and descriptions in comments. Search the repo for "ConformanceIt" for examples. |

OrphanDependents is deprecated. We should update the test to use deleteOptions.PropagationPolicy (https://github.com/kubernetes/kubernetes/blob/master/staging/src/k8s.io/apimachinery/pkg/apis/meta/v1/types.go#L455). Could you update the test to use the getBackgroundOptions() instead of getNonOrphanOptions()? That's just an API change, shouldn't cause any behavior change.

Could you update the description to match the description in "ConformanceIt"?

ditto. Please update the test to use DeletePropagationOrphan.

This just requires a change in the comment. Both OrphanDependents and PropagationPolicy are default to nil.

Please update to DeletePropagationBackground.

Please use DeletePropagationOrphan policy.

Tests using deprecated features should not be added to conformance. |

Thanks. I'll wait for @caesarxuchao to re-review before approving. Conformance should test GA, non-deprecated features. |

I think https://k8s-gubernator.appspot.com/build/kubernetes-jenkins/pr-logs/pull/60116/pull-kubernetes-verify/79482/ is not a legitimate failure. All PRs seem to be failing the same way |

All the tested features here have been stable for more than 1 year. GC of custom resources have flakeness in tests but they are not tested here. |

FYI, some tests failed. /approve |

What this PR does / why we need it:
The garbage collector is a core component of kubernetes and needs to be tested by conformance, so its functionality can be relied on in any kubernetes environment.
As we can see in testgrid, the garbage collector tests being promoted by this PR are consistently passing. And the intention to promote them to conformance tests was laid out by this document
Special notes for your reviewer:
The last two tests in this file are not added as conformance tests because they involve beta features (custom resources and cronjobs), and conformance tests are only allowed for features in GA.
