Hi all, I want to get started with Selenium for testing Ajax. I followed the installation instructions on http://seleniumhq.org/projects/on-rails/ but get an error when running the rakefile in step 4. I get this error: "uninitialized constant ActionView::Base::Helpers (NameError)" The full output is here: http://pastie.org/641664 The only mention of this error I could find on the web is here: http://en.blog.improveit.com.br/articles/2009/03/27/new-selenium-on-rails-is-out but the fix presented in the comments there had no effect for me. I had the impression that Selenium was a very popular and commonly used tool in the Rails community so I was surprised it didn''t just work out of the box and that I haven''t found any other mention of the error. Has anyone seen this before? Any idea what to try? Thanks in advance.
