+
+Pod Security admission has very thorough integration test coverage, including:
+- Generated test fixtures for failing & passing pods across every type of check, version and level.
+- Tests with only GA feature gates enabled, and the default set.
+- Tests running as a built-in admission controller & webhook.
+- Tests pods run directly & via a controller
+
+##### e2e tests
+
+There are no Pod Security specific E2E tests (we rely on integration test coverage instead), but the
+Pod Security admission controller is enabled in E2E clusters, and all E2E test namespaces are
+labeled with the enforcement label for Pod Security.

 Three metrics will be introduced:
