@@ -6392,6 +6392,11 @@ NOTE: While Spring's test framework caches application contexts between tests an
a context for tests sharing the same configuration, the use of `@MockBean` or `@SpyBean`
influences the cache key, which will most likely increase the number of contexts.
TIP: If you are using `@SpyBean` to spy on a bean with `@Cachable` methods that refer
to parameter's by name, your application must be compiled with `-parameters`. This
ensures that the parameter names are available to the caching infrastructure once the
bean has been spied upon.
