Creating the User Friendship

My very first assertion to check the flash[:error] in user_friendships controller test is blowing up

` context "#create" do context "when not logged in" do should "redirect to the login page" do get :new assert_response :redirect assert_redirected_to login_path end end

context "when logged in " do
  setup do
    sign_in users(:zeb)
  end
 end
  context "with no friend_id"
   setup do
     post :create
    end

      should "set the flash error message" do
        assert !flash[:error].empty?
      end
   end
 end

with this error in terminal:

1) Error:
    test: #create should set the flash error message. (UserFriendshipsControllerTest):
    NoMethodError: undefined method `empty?' for nil:NilClass

Jason Seifer, thanks for responding! Turns out I had two "ends" at the end of the '#new' method, thus blowing everything up.

I'm having this same problem, only I don't think I have any extra 'end's. Here's what's in my user_friendships_controller:

class UserFriendshipsController < ApplicationController
before_filter :authenticate_user!, only: [:new]

def new
    if params[:friend_id]
        @friend = User.where(profile_name: params[:friend_id]).first
        raise ActiveRecord::RecordNotFound if @friend.nil?
        @user_friendship = current_user.user_friendships.new(friend: @friend)
    else
        flash[:error] = "Friend Required"
    end
rescue ActiveRecord::RecordNotFound
    render file: 'public/404', status: :not_found
end

def create
    if params[:friend_id]
    else
        flash[:error] = "Friend required"
        redirect_to root_path
    end
end
end
