 **Note:** *Not required until targeted at a release.*
+The goal is to ensure that we don't accept enhancements with inadequate testing.
+All code is expected to have adequate tests (eventually with coverage
+expectations). Please adhere to the [Kubernetes testing guidelines][testing-guidelines]
+when drafting this test plan.
+[testing-guidelines]: https://git.k8s.io/community/contributors/devel/sig-testing/testing.md
+-->
 
-Consider the following in developing a test plan for this enhancement:
-- Will there be e2e and integration tests, in addition to unit tests?
-- How will it be tested in isolation vs with other components?
+[x] I/we understand the owners of the involved components may require updates to
+existing tests to make this code solid enough prior to committing the changes necessary
+to implement this enhancement.
 
-No need to outline all of the test cases, just the general strategy. Anything
-that would count as tricky in the implementation, and anything particularly
-challenging to test, should be called out.
+##### Prerequisite testing updates
 
-All code is expected to have adequate tests (eventually with coverage
-expectations). Please adhere to the [Kubernetes testing
-guidelines][testing-guidelines] when drafting this test plan.
+<!--
+Based on reviewers feedback describe what additional tests need to be added prior
+implementing this enhancement to ensure the enhancements have also solid foundations.

+##### Unit tests
+
+<!--
+In principle every added code should have complete unit test coverage, so providing
+the exact set of tests will not bring additional value.
+However, if complete unit test coverage is not possible, explain the reason of it
+together with explanation why this is acceptable.
 -->
 
-Both integration and e2e tests will be required in addition to unit tests.
+<!--
+Additionally, for Alpha try to enumerate the core package you will be touching
+to implement this enhancement and provide the current unit coverage for those
+in the form of:
+- <package>: <date> - <current test coverage>
+The data can be easily read from:
+https://testgrid.k8s.io/sig-testing-canaries#ci-kubernetes-coverage-unit
+This can inform certain test coverage improvements that we want to do before
+extending the production code to implement this enhancement.
