Add verification that a policy for last_n is predefined.
You can assert that both are TEMPORARY.

For TEMPORARY pages, make an assertion that either they expire or have a limit
on number of pages.

Done.

+  OfflinePageClientPolicy policy =
+      ClientPolicyController::GetInstance().GetPolicy(kBookmarkNamespace);
+  EXPECT_EQ(policy.name_space, "bookmark");
+}

+} // namespace offline_pages
