Hello all,

I've just gotten started using BDD with RSpec/Cucumber/Webrat and Rails and I've run into some frustration trying to get my view spec to pass.

First of all, I am running Ruby 1.9.1p129 with Rails 2.3.2, RSpec and RSpec-Rails 1.2.6, Cucumber 0.3.11, and Webrat 0.4.4.

Here is the code relevant to my question

config/routes.rb:

map.b_posts                  'backend/posts',
                             :controller => 'backend/posts',
                             :action => 'backend_index',
                             :conditions => { :method => :get }

map.connect                  'backend/posts',
                             :controller => 'backend/posts',
                             :action => 'create',
                             :conditions => { :method => :post }

views/backend/posts/create.html.erb:

<% form_tag do %>
<% end %>

*spec/views/backend/posts/create.html.erb_spec.rb:*

describe "backend/posts/create.html.erb" do  
  it "should render a form to create a post" do
    render "backend/posts/create.html.erb"
    response.should have_selector("form", :method => 'post', :action => b_posts_path) do |form|
      # Nothing here yet.
    end
  end
end

Here is the relevant part of the output when I run script/spec:

'backend/posts/create.html.erb should render a form to create a post' FAILED
expected following output to contain a <form method='post' action='/backend/posts'/> tag:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd"&gt;
<html><body><form action="/backend/posts" method="post">
</form></body></html>

It would appear to me that what have_selector is looking for is exactly what the template generates, yet the example still fails. I am very much looking forward to seeing my error (because I have a feeling it is my error). Any help is much appreciated!

A: 

If you want to keep the block try using rspec-rails matchers instead of the webrat matchers.

describe "backend/posts/create.html.erb" do  
  it "should render a form to create a post" do
    render "backend/posts/create.html.erb"
    response.should have_tag("form[method=post][action=?]", b_posts_path) do |form|
      with_tag('input')
      # ... etc
    end
  end
end
