Parameters

\Drupal\Core\Url $url: The page for this URL will be loaded.

string $hit_or_miss: 'HIT' if a page cache hit is expected, 'MISS' otherwise.

array|false $tags: When expecting a page cache hit, you may optionally specify an array of expected cache tags. While FALSE, the cache tags will not be verified. This tests whether all expected tags are in the page cache tags, not that expected tags and page cache tags are identical.
