selenium - 在 TestNG 中使用 @Factory 和 @DataProvider 并映射到迭代器

Question

我想遍历excel表并使用@dataprovider获取数据然后希望使用@Factory和@dataProvider在以下模式中执行方法@dataProvider返回的数据类型是

这是我正在寻找的执行模式

Before Test : 1
testMethod0 : Method 0 data set 1
testMethod1 : Method 1 data set 1
testMethod2 : Method 0 data set 1
After Test : 1

Before Test : 2
testMethod0 : Method 0 data set 2
testMethod1 : Method 1 data set 2
testMethod2 : Method 0 data set 2
After Test : 2
.
.
and so on 

请帮帮我

这就是我的 excel 工作表的样子

+--------------------+--------------------+--------------------+
| Method0Data        | Method0Data        | Method0Data        |
+--------------------+--------------------+--------------------+
|Method 0 data set 1 |Method 1 data set 1 |Method 0 data set 1 |
|Method 0 data set 1 |Method 1 data set 1 |Method 0 data set 1 |
|Method 0 data set 1 |Method 1 data set 1 |Method 0 data set 1 |
+--------------------+--------------------+--------------------+

当我执行上面的代码时，我得到以下错误，不知道为什么
