连接 cypress 与 DB 时连接 ETIMEDOUT

Question

我试图在 cypress 的测试中从 Db 获取令牌，但连接超时 10 次中有 8 次在下面附加错误和堆栈跟踪

当我尝试通过 Db Visualizer 发送查询或通过连接到同一个 Db 的测试 Web 应用程序访问数据时，它工作正常并且没有超时想知道它是否与我正在使用的代码或服务器有关我的索引文件中的以下代码进行连接

////////connect to DB////////////
const mysql = require('mysql');
function queryTestDb(query, config) {
  // creates a new mysql connection using credentials from cypress.json env's
  const connection = mysql.createConnection(config.env.db);
  // start connection to db
  connection.connect();
  // exec query + disconnect to db as a Promise
  return new Promise((resolve, reject) => {
    connection.query(query, (error, results) => {
      if (error) {
        connection.end();
        reject(error);
      } else {
        connection.end();
        // console.log(results)
        return resolve(results);
      }
    });
  });
}

module.exports = (on, config) => {
  // Usage: cy.task('queryDb', query)
  on('task', {
    queryDb: (query) => {
      return queryTestDb(query, config);
    },
  });
};
