validating length- rspec

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")

    fill_in "Title", with: "My todo list"
    fill_in "Description", with: "This is what I'm doing today."
    click_button "Create Todo list"

    expect(page).to have_content("My todo list")
  end

  it "Diplays an error when the todo list has a title less than 3 characters" do
    expect(TodoList.count).to eq(0)

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

    fill_in "Title", with: "Hi"
    fill_in "Description", with: "This is what I'm doing today."
    click_button "Create Todo list"

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

    visit "/todo_lists"
    expect(page).to_not have_content("This is what I'm doing today")

  end

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

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

    fill_in "Title", with: "Grocery list"
    fill_in "Description", with: ""
    click_button "Create Todo list"

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

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


end

when i do the command

bin/rspec spec/features/todo_lists/create_spec.rb

i get 1 failure

[deprecated] I18n.enforce_available_locales will default to true in the future. If you really want to skip validation of your locale you can set I18n.enforce_available_locales = false to avoid this message.

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: Edit | Back"
     # ./spec/features/todo_lists/create_spec.rb:46:in `block (2 levels) in <top (required)>'

Finished in 0.44264 seconds
3 examples, 1 failure

The error is telling you that "it expected the page to have the content 'error' but it found the text 'Todo list was successfully created. Title: Grocery list Description: Edit | Back' " instead. My guess is that you have not yet added the validation to the TodoList Modal.

     validates :description, presence: true

The above code should enable the test to pass

Hi Adam,

I have added that to my model, here it is:

class TodoList < ActiveRecord::Base
  validates :title, presence: true
  validates :title, length: {minimum: 3}
  validate :description, presence: true
end

but i still get the error?
