[英]Why I am getting Data Provider MisMatch error when I try to read from excel file?
I am trying to do data driven testing and I am not able to figure it out why I am getting data mismatch.我正在尝试进行数据驱动测试,但我无法弄清楚为什么我会得到数据不匹配。 I am trying to automate just usernames and that is in form of string.
我正在尝试仅自动化用户名,并且是字符串形式。 Can you please review my code and tell me what I am doing wrong?
您能否查看我的代码并告诉我我做错了什么? Below are two files.
下面是两个文件。 one is my main method file and one is my excel config file.
一个是我的主要方法文件,一个是我的 excel 配置文件。 I have also attached screenshot of my error.
我还附上了我的错误截图。 Any help would be appreciated.
任何帮助,将不胜感激。 Thank you.
谢谢你。

Error Screenshot:错误截图:
You are declaring Object[][] credentials = new Object[rows][2];
您正在声明
Object[][] credentials = new Object[rows][2];
but you fill only one column keeping other column empty ( null
).但您只填写一列,其他列为空(
null
)。 Hence the dimension of your array does not match the number of arguments your method accepts.因此,您的数组维度与您的方法接受的 arguments 的数量不匹配。
Fix it with changing that line to:通过将该行更改为以下内容来修复它:
Object[][] credentials = new Object[rows][1];
