        Object[][] data1= new Object[rows][2];
        for(int i=0;i<rows;i++)
        {
            data1[i][0]=config.getData(0, i, 0);
            data1[i][1]=config.getData(0, i, 1);

        }
        return data1;
    }

}

Answer 1

DataProvider需要方法CPToAdslogin来获取参数。

数据提供程序试图传递%2个参数，但方法cptoadsLogin接受%0

您需要将方法签名更改为接收2个参数

@Test(dataProvider = "toadsLogin")
public void cptoadsLogin(String user, String pwd) throws Exception
{
    ToadsLogin tlogin=new ToadsLogin(driver);
    tlogin.unpwd(user, pwd);
    tlogin.clikonLogin();
    Thread.sleep(5000);
    driver.close();
}
