Topic: Changing a functional test after adding user authentication

Hi, I hope this is the right section to post this.  I have added user authentication to my rails application using this railscast (270#): http://railscasts.com/episodes/270-auth … -rails-3-1

The problem is, now two of my functional tests do not pass:

 1) Failure:
test_should_create_user(UsersControllerTest) [/home/tim/fairym/test/functional/users_controller_test.rb:20]:
"User.count" didn't change by 1.
<4> expected but was
<3>.

  2) Error:
test_should_update_user(UsersControllerTest):
NoMethodError: undefined method `stringify_keys' for "980190962":String

Here are the tests:

require 'test_helper'
setup do
    @input_attributes ={
    :email => "jojo@yahoo.com", 
    :first_name => "sam",
    :last_name => "Sammy",
    :gender => "Male",
    :orientation => "Bi",
    :location => "London",
    :date_joined => 2012 - 10 - 18
    :date_of_birth => 1987 - 10 - 18
    :last_online => DateTime.now.to_date
    :password => "private",
    :password_confirmation => "private"
    :admin => false
    }
test "should update user" do

    put :update, :id => @user.to_param, :user => @input_attributes
    assert_redirected_to users_path
  end
  test "should create user" do
    assert_difference('User.count') do
      post :create, :user => { @input_attributes }
    end

    assert_redirected_to users_path

end

sessions_controller.rb

def create
  user = User.find_by_email(params[:email])
  if user && user.authenticate(params[:password])
    session[:user_id] = user.id
    redirect_to root_url, :notice => "Logged in!"
  else
    flash.now.alert = "Invalid email or password"
    render "new"
  end
end

def destroy
  session[:user_id] = nil
  redirect_to root_url, :notice => "Logged out!"
end

application_controller.rb

private

def current_user
  @current_user ||= User.find(session[:user_id]) if session[:user_id]
end
helper_method :current_user

I would like to make those tests pass by adding authentication, how can I do that?
