Rails 4 Todo List - Test Failure

Question

Good morning,

I'm currently working on Build a Todo List Application with Rails 4, lesson Write our First Test. After I run the first test, I get an error and the test fails. I've gone through the lessons and double checked to make sure that I do not have any typos or missing items. I've read trough the forums, but have not found anything that has resolved my issue.

I'm using the Treehouse VM for Windows and setup detailed in the Installing a Ruby Development Environment lessons. Perhaps the Treehouse VM that I'm using is slightly different than the version in the videos?

I've taken screenshots of the gem file, spec_helper, create_spec, and the error that I'm getting. At this point, I can not move forward and I'm at a stopping point. Any help would be greatly appreciated!

Thanks,

Alan

OK, now I noticed a typo in your test: it says vist instead of visit. Fix that and see if it works now.

Can you show us your controller and view for this? Also, it is better to copy the code and paste it here using ruby markdown (see "Markdown Cheatsheet" below, just above the Post answer button).

Sure, here is the code below.

Thanks, Alan

todo_lisis_controller.rb:

class TodoListsController < ApplicationController
  before_action :set_todo_list, only: [:show, :edit, :update, :destroy]

  # GET /todo_lists
  # GET /todo_lists.json
  def index
    @todo_lists = TodoList.all
  end

  # GET /todo_lists/1
  # GET /todo_lists/1.json
  def show
  end

  # GET /todo_lists/new
  def new
    @todo_list = TodoList.new
  end

  # GET /todo_lists/1/edit
  def edit
  end

  # POST /todo_lists
  # POST /todo_lists.json
  def create
    @todo_list = TodoList.new(todo_list_params)

    respond_to do |format|
      if @todo_list.save
        format.html { redirect_to @todo_list, notice: 'Todo list was successfully created.' }
        format.json { render action: 'show', status: :created, location: @todo_list }
      else
        format.html { render action: 'new' }
        format.json { render json: @todo_list.errors, status: :unprocessable_entity }

        format.json { render json: @todo_list.errors, status: :unprocessable_entity }
      end
    end
  end

    @todo_list.destroy
    respond_to do |format|

      @todo_list = TodoList.find(params[:id])
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def todo_list_params
      params.require(:todo_list).permit(:title, :description)
    end
end

new.html.erb:

<%= render 'form' %>

<%= link_to 'Back', todo_lists_path %>

index.html.erb:

<h1>Listing todo_lists</h1>

      <tr>

Issue resolved, it was a typo on my part. Thanks for the assistance. Here is the correct code.

require 'spec_helper'

describe "Creating todo lists" do
    it "redirects to the todo list index page on success" do
        visit "/todo_lists" 
        click_link "New Todo list"
        expect(page).to have_content("New todo_list")
    end
end
