I don't know why I am getting a failure?

Have inputted the code and I am getting this error.

Failures:

  1) Viewing todo items displays the title of the todo list
     Failure/Error: visit "/todo_list"
     ActionController::RoutingError:
       No route matches [GET] "/todo_list"
     # ./spec/features/todo_items/index_spec.rb:7:in `visit_todo_list'
     # ./spec/features/todo_items/index_spec.rb:18:in `block (2 levels) in <top (required)>'

  2) Viewing todo items displays no items when a todo list is empty
     Failure/Error: visit "/todo_list"
     ActionController::RoutingError:
       No route matches [GET] "/todo_list"
     # ./spec/features/todo_items/index_spec.rb:7:in `visit_todo_list'
     # ./spec/features/todo_items/index_spec.rb:25:in `block (2 levels) in <top (required)>'

Here is my code

require 'spec_helper'

describe "Viewing todo items" do
  let!(:todo_list) { TodoList.create(title: "Grocery list", description: "Groceries") }

  def visit_todo_list(list)
    visit "/todo_lists"
    within "#todo_list_#{list.id}" do
      click_link "List Items"
    end
  end

  it "displays the title of the todo list" do
    visit_todo_list(todo_list)
    within("h1") do
      expect(page).to have_content(todo_list.title)
    end
  end  

  it "displays no items when a todo list is empty" do
    visit_todo_list(todo_list)
    expect(page.all("ul.todo_items li").size).to eq(0)
  end

  it "displays item content when a todo list has items" do
    todo_list.todo_items.create(content: "Milk")
    todo_list.todo_items.create(content: "Eggs")

    visit_todo_list(todo_list)

    expect(page.all("ul.todo_items li").size).to eq(2)

    within "ul.todo_items" do
      expect(page).to have_content("Milk")
      expect(page).to have_content("Eggs")
    end
  end
end

Run rake routes in the terminal - do you have a route called '/todo_list'?

Post up your routes.rb file, too. And link to your Github repo, if you have one.

treehouse:~/projects/odot (master *) $

And here is my routes.rb file.

Odot::Application.routes.draw do
  resources :todo_lists do
    resources :todo_items
  end
  root 'todo_lists#index'

Don't know how to link to my Github Repo. I have looked in my Github and I don't see the project.
