selenium与数据库无关。你需要另一种技术。为此，请使用jdbc。看到了吗https://www.tutorialspoint.com/jdbc/index.htm.
maven依赖关系：

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
        <artifactId>mssql-jdbc</artifactId>
    <version>8.4.1.jre8</version>
</dependency>

或者将jdbcjar添加到项目中。
假设db位于具有windows身份验证的sql server express上，db名称为“mydatabase”，而具有otps的名为“otp”的表如下所示：

使用jdbc：

package db;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class OtpManager {

    public static Connection connectSqlDb(String dbName) throws SQLException {
        String serverName = "PC NAME\\SQLEXPRESS";
        return DriverManager.getConnection("jdbc:sqlserver://" + serverName + ";databaseName=" + dbName + ";integratedSecurity=true");
    }

    public static String getLastOptForUser(String userName) throws SQLException {
        String otp = null;
        Connection connection = connectSqlDb("MyDatabase");
        Statement statement = connection.createStatement();
        String query = "select top (1) otp from [MyDatabase].[dbo].[OTP] where username = '" + userName + "' order by created desc";
        ResultSet result = statement.executeQuery(query);
        while(result.next()) {
            otp = result.getString("otp");
        }
        return otp;
    }

    public static void main(String[] args) throws SQLException {
        String userName = "user1";
        String lastOtp = getLastOptForUser(userName);
        System.out.println(lastOtp);
    }

}

输出：

2222

在 selenium 测试中，您可以使用otp值： element.sendKeys(String string);
