Rotation validation is skipped in Ginkgo test path, reducing coverage.
The checkRotationGinkgo function calls util.CheckRotation only when the test is run as a regular Go test. For Ginkgo tests, the function logs and skips, meaning pre/post rotation cert combinations are never validated in the OTE path. This directly reduces test coverage for a critical validation.
The code comment incorrectly states that t.Run() is part of the testing.TB interface—it is not. The testing.TB interface lacks the Run() method needed for subtests, making direct refactoring of util.CheckRotation to accept testing.TB infeasible without removing the t.Run() calls.
Consider either:
- Refactoring
util.CheckRotationto remove subtest structure and accepttesting.TB, or - Implementing the rotation check logic directly in
checkRotationGinkgowithout relying on subtests.

Why More Than PR #305 (Metrics: +64 net)?

The +124 net is necessary because:
