What language can be used to automate web test?

I'm working on a Web Service which is associated with a form that requires inputs from user. The problem is the fields are quite large, approximately 200 fields need to be filled in. I would like to ask what language would serve best in this case, in term of automating inputs.

I tried Ruby with Watir, but it doesn't work as expected when dealing with iframe. So I'm looking for an alternative solution. Any feedback or suggestion would be greatly app开发者_如何学编程reciated. My WS is developed using ASP.NET and Java Script.

Thanks,

Selenium may provide the functionality you're looking for. It is a testing framework that supports recording tests, so writing scripts is optional. It does however provide scripting functionality in a variety of languages, including Java, C#, Ruby, Python and more.

Have you tried WatiN? It is an open source automated test framework for Web application. And it support C# and other managed languages.
