Ruby on Rails

I assume you are trying to mock the Post to separate it from the controller action.  You may have better luck with the double/stub nomenclature:

Hi guys,

I'm starting to write tests and I writing a functional test for my 'create' action.

So, basically I have the following test:

  describe '#create' do

    

    @attributes = { title: 'New post', description: 'Please add some text here', location: 'Anywhere' }

    context 'when logged in' do 

      login_user

      before { post :create, @attributes }

      it 'should create a new post' do 

        post = mock(Post, @attributes)

        assigns(:post).should_not be_nil

        Post.should_receive(:save).and_return(post)

        response.should redirect_to successful_submitted_posts_path

      end

      it 'should NOT create a new post' do 

      end

    end

    context 'when NOT logged in' do

      before { post :create, @attributes }

      it { response.should_not be_successful }

      it { response.should redirect_to new_user_session_path }

    end

  end

But it's failing and I don't get understand why.

1) PostsController#create when logged in should create a new post

     Failure/Error: post = mock(Post, @attributes)

     ArgumentError:

       wrong number of arguments (3 for 2)

     # ./spec/controllers/posts_controller_spec.rb:40:in `block (4 levels) in <top (required)>'

Finished in 0.77996 seconds

6 examples, 1 failure

why mock method expects 3 arguments? what they should be?

I have read on some blogs this kind of syntax.

mock(Object, hash)

And this is my controller:

# encoding: utf-8

class PostsController < ApplicationController

  load_and_authorize_resource

  before_filter :authenticate_user!

  respond_to :html

  def new

    @post = Post.new

  end

  def create

    @post = current_user.posts.build(params[:post])

    if @post.save

      redirect_to successful_submitted_posts_path

    else

      render :new

    end

  end

  def successful_submitted; end

end

What I'm doing wrong?

Please give me some hints.

Thank you.
