php - PHPUnit Mock Database Connection Class -


i'm adding unit tests legacy codes in mvc framework. have model class called dbconnection initiate database connection, looks this:

class dbconnection     function __construct()    {        mysql_connect(hardcoded)    } }

every methods needs database access call dbconnection, this:

function insertuser() {     $db = new dbconnection();     $sql = "select .....     ....  }

if want have option of either connect different testing database or using xml file mock database, how should without refactor code?
