I pretty much copied this word for word in his example.

fill_in "Title", with: options[:title]

click_button "Create Todo list"

end

it "redirects to the todo list index page on success" do create_todo_list expect(page).to have_content("My Todo Lists") end

I am not getting this error now.

Failures:

  1) Creating todo lists displays an error when the todo list has no description
     Failure/Error: expect(page).to have_content("error")
       expected to find text "error" in "Todo list was successfully created. Title: Grocery list Description: Food Edit | Back"
     # ./spec/features/todo_lists/create_spec.rb:63:in `block (2 levels) in <top (required)>'

This is my amended code.

require 'spec_helper'

describe "Creating todo lists" do
  def create_todo_list(options={})
    options[:title] ||= "My todo list"
    options[:description] ||= "This is my todo list."

    visit "/todo_lists"
    click_link "New Todo list"
    expect(page).to have_content("New todo_list")

    fill_in "Title", with: options[:title]
    fill_in "Description", with: options[:description]
    click_button "Create Todo list"
  end

  it "redirects to the todo list index page on success" do
    create_todo_list
    expect(page).to have_content("My todo list")
  end

  it "displays an error when the todo list has no title" do

No worries, I can read the error but I just want to see the specs in question. Example: 

it "displays an error when the todo list has no description" do expect(TodoList.count).to eq(0)

  create_todo_list title: "Grocery list", description: ""

  expect(page).to have_content("error")
  expect(TodoList.count).to eq(0)

  visit "/todo_lists"
  expect(page).to_not have_content("Grocery list")
end

Also, these specs are testing for the description being empty but one has description as food:

it "displays an error when the todo list has no description" do expect(TodoList.count).to eq(0)

  create_todo_list title: "Grocery list", description: ""

  expect(page).to have_content("error")
  expect(TodoList.count).to eq(0)

  visit "/todo_lists"
  expect(page).to_not have_content("Grocery list")
end

it "displays an error when the todo list has no description" do expect(TodoList.count).to eq(0)

  create_todo_list title: "Grocery list", description: "Food"

  expect(page).to have_content("error")
  expect(TodoList.count).to eq(0)

  visit "/todo_lists"
  expect(page).to_not have_content("Grocery list")
end

It looks like the error is saying it can't find "error" on the page and it's finding this: 

Todo list was successfully created. Title: Grocery list Description: Food Edit | Back"

Description is being filled in with Food Edit | Back for some reason, take a look at your view and the form for syntax errors.

Also, if you just want to post the error and make sure it's included in the code markdown format, it's hard to read everything as is.

When I filled the description with a "" it passed. I take it that's not the problem. I am at a loss as to where the syntax error is.

Anyway can you post just the failing test and the revised test? Just the parts of the spec you have in question, not all of the spec.
