java - 如何读取 Excel 并获取多个值并使用 selenium Web 驱动程序和 testNG 中的数据提供程序连接它们

Question

我想读取一个 excel 并一次获取 10 条记录，并使用 selenium Web 驱动程序和 testNG 中的数据提供程序将它们连接起来。例如，Excel 工作表有两列，即 col 1、col 2 和 10 行。现在，我想使用 selenium web-driver 即“A，B，C，D，E，F，G，H，J，I”作为值，将从 excel 中获取的结果作为值传递到文本框中。在这里， row1 col1 包含 "A" 和 row 1 col 2 包含 "," 。同样，其余的行和列也是如此。你能提供我这个逻辑的代码吗？
