rspec users - Nov 2010 - undefined method `contain' for #<RSpec::Core::ExampleGroup::Nested_1:0x10595b1a8>

Here''s my Gemfile:

group :development, :test do
>   gem ''rspec-rails'', ''2.0.0''
>   gem ''cucumber-rails'', ''0.3.2''
>   gem ''capybara'', ''0.4.0.rc''
> end

and here''s my spec:

describe "welcome/index.html.haml" do
>   it "displays ''Problem Child'' in the header"
do
>     render
>     rendered.should contain("Problem Child")
>   end
> end

This results in the error given in the subject:

Failures:

the header

Does the "contain" matcher come with Webrat? Is that why the RSpec
book
seems to be lying to me? I''m trying to get the feel of RSpec and I love
the
idea of speccing views. I''ve been approximately following along with
The
RSpec Book. I''m using Capybara instead of Webrat because Webrat
wasn''t
playing well with Rails 3 (I forget the details).

Thanks!

The book says "these examples use Webrat" and you choose Capybara (a
perfectly good option, but not for the examples in the book). Not sure who is
lying to you, but it is not the book :)

Webrat works fine for all of the examples in the book. I''d recommend
using it to go through the book to get the feel for the process.

Also, Capybara''s matchers are not available in view specs or helper
specs (see https://github.com/rspec/rspec-rails/issues/closed#issue/242).

HTH,
