PHPUnit 不连接到数据库

Question

我已经建立了一个基于 Docker Sail（Windows 上的 Ubuntu）的项目， 该项目工作正常，除非 PHPUnit 连接到数据库。

我尝试使用“sudo apt-get install php-mysql”安装 mysql

现在我得到这个错误

这是我的 docker 文件

这是我关于使用测试的 phpunitxml

    <server name="APP_ENV" value="testing"/>
    <!-- <server name="DB_CONNECTION" value="sqlite"/> -->
    <!-- <server name="DB_DATABASE" value=":memory:"/> -->

这是关于数据库连接的 .env 文件

 DB_CONNECTION=mysql
 DB_HOST=mysql
 DB_PORT=3306

Answer 1

请尝试将DB_HOST 更改为localhost。 Mysql 服务应在 docker 容器内的 localhost/127.0.0.1 运行。
