[comment]: # (The below checklist is for code changes. Not all boxes necessarily need to be checked. Build, doc, and template changes do not need to fill out the checklist.) # Tests Checklist - [ ] Have end-to-end Ginkgo tests been run on your cluster and passed? To bootstrap your cluster to run the tests, follow [these instructions](/otelcollector/test/README.md#bootstrap-a-dev-cluster-to-run-ginkgo-tests). - Labels used when running the tests on your cluster: - [ ] `operator` - [ ] `windows` - [ ] `arm64` - [ ] `arc-extension` - [ ] `fips` - [ ] Have new tests been added? For features, have tests been added for this feature? For fixes, is there a test that could have caught this issue and could validate that the fix works? - [ ] Is a new scrape job needed? - [ ] The scrape job was added to the folder [test-cluster-yamls](/otelcollector/test/test-cluster-yamls/) in the correct configmap or as a CR. - [ ] Was a new test label added? - [ ] A string constant for the label was added to [constants.go](/otelcollector/test/utils/constants.go). - [ ] The label and description was added to the [test README](/otelcollector/test/README.md). - [ ] The label was added to this [PR checklist](/.github/pull_request_template). - [ ] The label was added as needed to [testkube-test-crs.yaml](/otelcollector/test/testkube/testkube-test-crs.yaml). - [ ] Are additional API server permissions needed for the new tests? - [ ] These permissions have been added to [api-server-permissions.yaml](/otelcollector/test/testkube/api-server-permissions.yaml). - [ ] Was a new test suite (a new folder under `/tests`) added? - [ ] The new test suite is included in [testkube-test-crs.yaml](/otelcollector/test/testkube/testkube-test-crs.yaml).
