     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來獲取參數。

The data provider is trying to pass 2 parameters but the method cptoadsLogin takes 0

您需要更改方法簽名接收2個參數

@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(); 
} 

user將有來自data1[i][0]和pwd值將具有值從data1[i][1]
