我在 docker 容器中添加了 Behat：
composer require behat/behat behat/mink behat/mink-extension laracasts/behat-laravel-extension --dev
vendor/bin/behat --init
我在运行 phpunits 时遇到了同样的错误，但在 question 中发现了它。
【问题讨论】：
【参考方案1】：我认为您没有通过容器运行 Behat，并且它没有与 mysql 容器链接。 试试这个
docker-compose run php php /var/www/html/vendor/bin/behat --init
或类似的东西，以便您使用与 mysql 链接的 php 容器执行 behat
