I’m following the instructions on installing Selenium on rails: “Run the  
Rakefile in the plugin???s directory to run the tests in order to see  
that  
everything works”

When I rake:

DKMac:selenium-on-rails DK$ rake test

I get the following error:

/Users/DK/.rvm/gems/ruby-1.8.7-p174/gems/activesupport-2.3.8/lib/active\_support/dependencies.rb:105:in  
`const\_missing’: uninitialized constant ActionView::Base::Helpers  
(NameError)

Am I correct in running the rake task directly from the plugin directory  
as  
above?

Using Rails 2.3.8, Ruby 1.8.7. The issue above looks like was something  
that  
was coming up for people who tried to install this with rails 2.1, but  
sounds like was fixed.

Thanks,

David
