rspec to xhr

when i want to test an ajax action, it always can’t passed. The action code is:

POST /posts/:id/comments

def create @comment = @post.comments.build(params[:comment])

if @comment.save
  flash[:notice] = 'Comment was successfully created.'
  render :update do |page|
    page.insert_html :bottom, 'comments', :partial => 'posts/comment', :object => @comment
    page.replace_html 'comment', :partial => 'comment', :object => Comment.new
  end
else
  render :update do |page|
    page.replace_html 'comment', :partial => 'comment', :object => @comment
  end
end

end

and the test code is:

describe “handling POST /posts/:id/comments” do

before(:each) do
  @post = Post.new
  @comment = Comment.new
  Post.stubs(:find).returns(@post)
  @post.comments.stubs(:build).returns(@comment)
end

it "with successful save" do
  @comment.expects(:save).returns(true)
  xhr :post, :create, :post_id => @[post.id](http://post.id), :comment => {}
  response.should have_rjs(:insert_html, :bottom, 'comments')
  response.should have_rjs(:replace_html, 'comment')
end

it "with failed save" do
  @comment.expects(:save).returns(false)
  xhr :post, :create, :post_id => @[post.id](http://post.id), :comment => {}
  response.should have_rjs(:replace_html, 'comment')
end

end

The result is: 1) ‘CommentsController handling DELETE /comments/:id with successful destroy’ FAILED No RJS statement that removes ‘comment_’ was rendered. ./spec/controllers/comments_controller_spec.rb:38:

‘CommentsController handling POST /posts/:id/comments with successful save’ FAILED bottom. ./spec/controllers/comments_controller_spec.rb:16:

But I can do it successfully by browser. So I think there’s something wrong with my rspec codes. Can anyone help me? Thanks in advanced.
