rspec users - May 2011 - rspec help for create user test

My user controllers ''create'' action looks like:


def create
  @user = User.new(params[:user])

  @user.user_name = params[:user][:user_name]
  @user.email = params[:user][:email]

  if @user.is_valid?
     @user.status = 2
     @user.save!

      UserMailer.new_user(@user).deliver

     redirect_to(@user, :notice => "user was created successfully")
  else
     render :action => ''new''

  end


end



My test is:


describe "POST ''create'' do
  it "should be successful" do

    user = mock_model(user)
    user.sub(:new).and_return(user)

    post ''create''
    response.should redirect_to(user)

  end

end


error:

 Failure/Error: post ''create''
     NoMethodError:
       You have a nil object when you didn''t expect it!
       You might have expected an instance of ActiveRecord::Base.
       The error occurred while evaluating nil.[]
     # ./app/controllers/users_controller.rb:44:in `create''
     # ./spec/controllers/users_controller_spec.rb:81

Hello. nil.[] means the code is trying to call an array getter method
(the_array[the_index]) on nil. In the action,
"params[:user][:user_name]" is
causing the error because there is no ":user" key in
"params". Here is how
you want to invoke the request:

post :create, :user => {:user_name => ''foo'', :email
=> ''test at example.com''}

Hope that fixes it.
