Undefined array key during PHPUnit tests

[duakayra]

While running PHPUnit tests with WordPress, wp-multilang (version 2.4.10) triggers a PHP warning in class-wpm-install.php on line 271 with if(is_array($available_translations[ $locale ])). The issue occurs because WordPress provides test languages, such as Japanese, that are not available in wp-multilang, leading to an "Undefined array key" warning when trying to access those translations.

Stack trace:

PHP Warning:  Undefined array key "ja_JP" in /home/contentcontrol/git/rfp/wp-content/plugins/wp-multilang/includes/class-wpm-install.php on line 271
