Changeset 53834 for trunk/tests/phpunit/tests/cache.php

Timestamp:

Message:

Tests: Add more test cases for WP_Object_Cache::is_valid_key().

A valid cache key for wp_cache_*() functions must be either an integer number or a non-empty string. To avoid potential compatibility issues or key collisions, a string that becomes empty after trim() should not be considered a valid cache key.

Follow-up to [53818], [53821], [53822].

Props tillkruess.
See #56198.
