problem with should_receive in controller spec

[Amit Kulkarni-6]

I am trying to write controller spec but i am getting some problem.
Following is the controller code:

def create
  @bb_post = @feature.posts.new( params[ :bb_post ] )
     if @bb_post.save
        flash[ :notice ] = 'Blog post was successfully created.'
        format.html { redirect_to( blog_bb_posts_url ) }
        format.xml  { render :xml => @bb_post, :status => :created,
:location => @bb_post }
      else
        format.html { render :action => "new" }
  format.xml  { render :xml => @bb_post.errors, :status =>
:unprocessable_entity }
      end
    end
  end

My controller spec is :
describe BbPostsController, "POST Create" do
context "Admin" do
    fixtures :users, :bb_posts

      it "should create post" do
       @post = mock_model(BbPost, :save => nil)
       BbPost.should_receive(:new).with('title' => 'Test123' ,'body' =>
'test_description', 'abstract' => 'test_abstract').and_return(@post)
       post :create
      end

      it "should save post" do
        @post = mock_model( BbPost, :body => "test_description", :title
=> "test123",  :abstract => "test_abstract" )
        BbPost.should_receive( :new ).and_return @post
        #~ @post.should_receive( :redirect_to
).with(blog_bb_posts_url).and_return(true)
        @post.should redirect_to( blog_bb_posts_url )
        post :create
      end
end
end

Now it gives me error

Spec::Mocks::MockExpectationError in 'BbPostsController POST Create
Admin should
 not create post without login'
<BbPost(id: integer, body: text, title: string, comment_count: integer,
tags: st
ring, published: boolean, inappropriate: boolean, permalink: string,
channel_fea
ture_id: integer, bb_post_category_id: integer, created_at: datetime,
updated_at
: datetime, abstract: text, view_count: integer, user_id: integer,
unsoliciteds_
count: integer, textilized: text, delta: boolean) (class)> expected :new
with ({
"abstract"=>"test_abstract", "body"=>"test_description",
"title"=>"Test123"}) on
ce, but received it 0 times

And it is pointing error at "BbPost.should_receive(:new).with('title' =>
'Test123' ,'body' => 'test_description', 'abstract' =>
'test_abstract').and_return(@post)"


and for second it gives error as
NoMethodError in 'BbPostsController POST Create Admin should save post'
You have a nil object when you didn't expect it!
The error occurred while evaluating nil.rewrite
(eval):15:in `edit_profile_url'
And it is pointing error at "@post.should redirect_to( edit_profile_url
)"


Please suggest something on this.I am not able to figure it out.

This should be:

   response.should redirect_to( blog_bb_posts_url )

>        post :create

This name, "should not create post without login," is not in the code  
above, so we have no way to diagnose this error. Please be sure to  
post matching code and failure message.

This is the one I explained above - the spec says "@post.should ..."  
instead of "response.should ..."

It's pretty hard to read the code in an email without any syntax  
highlighting and the email formatting things in unpleasant ways. Even  
if you include the code in email for posterity, please also post it to http://gist.github.com 
  or http://pastie.org/ or some such in future posts.

Thanks,
David
