[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
