我正在尝试进行数据驱动的测试,但无法弄清为什么我会遇到数据不匹配的情况。我正在尝试仅自动化用户名,并且采用字符串形式。您能否查看我的代码并告诉我我做错了什么? 以下是两个文件。一个是我的主要方法文件,另一个是我的excel配置文件。我还附有我的错误的屏幕截图。任何帮助,将不胜感激。谢谢。

文件1:

答案 0 :(得分:1)

您要声明Object[][] credentials = new Object[rows][2];,但您只填写一列,而另一列为空(null)。因此,数组的维数与方法接受的参数数量不匹配。

将行更改为:

Object[][] credentials = new Object[rows][1];
