Rewrite HealthCheckViewTests to not override CACHES.
Review Request #14612 — Created Sept. 12, 2025 and submitted — Latest diff uploaded
Apparently, using
@override_settings(CACHES=...)is not safe, and can
break later tests even though the setting is restored. This change
updates our view to encapsulate the cache checking in a couple methods
which can be safely spied on instead, the same way we do for
DATABASES.
Ran unit tests and saw that everything passed.
