When testing a view you want to stub the controller and render its view. In a before block, start by creating an instance of the controller that will render your view: <pre><code class="ruby">@controller = Posts.new(fake_request)</code></pre> <code>Posts</code> being the name of my controller. <code>fake_request</code> is a helper (TODO: explain more) Next we need to assign some values to pass to the view: <pre><code class="ruby">@controller.instance_variable_set(:@posts, [Post.new(:id => 1, :body => "Merb!")])</code></pre> In this example we are creating a controller instance variable called <code>@posts</code>, it's an array containing one instance of the Post object with 2 attributes set: @id@ and @body@. Finally, we can use the rspec matchers to make sure our views are ok. <pre><code class="ruby">describe "posts/index" do before( :each ) do @controller = Posts.new(fake_request) @controller.instance_variable_set(:@posts, [Post.new(:id => 1, :body => "Merb!")]) @body = @controller.render(:index) end it "should have something" do @body.should have_tag(:div, :class => :posts).with_tag(:div, :class => :post) end it "should wrap the body paragraph in a div with class 'post' and the post's id" do @body.should have_tag(:div, :class => :post, :id => @post.id).with_tag(:p, :class => :body) end it "should render the body body within a post div" do @body.should have_tag(:div,:id => @post.id).with_tag(:p) {|p| p.should contain(@post.body)} end end</code></pre> "look at the slapp demo app for more detailed example":http://www.socialface.com/slapp/
