Failure/Error: expect(page).to have_content("Content can't be blank.")

I am receiving this error:

1) Editing todo items is unsuccessful with no content Failure/Error: expect(page).to have_content("Content cannot be blank.") expected to find text "Content cannot be blank." in "That todo list item could not be saved. 2 errors prohibited this todo item from being saved: Content can't be blank Content is too short (minimum is 2 characters) Content" # ./spec/features/todo_items/edit_spec.rb:35:in `block (2 levels) in <top (required)>'

Here is my code from edit_spec.rb

require 'spec_helper'

describe "Editing todo items"  do
  let!(:todo_list) { TodoList.create(title: "Grocery list", description: "Groceries") }
  let!(:todo_item) { todo_list.todo_items.create(content: "Milk") }

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

  it "is successful with valid content" do
    visit_todo_list(todo_list)
    within("#todo_item_#{todo_item.id}") do
      click_link "Edit"
    end
    fill_in "Content", with: "Lots of Milk"
    click_button "Save"
    expect(page).to have_content("Saved todo list item.")
    todo_item.reload
    expect(todo_item.content).to eq("Lots of Milk")
  end


  it "is unsuccessful with no content" do
    visit_todo_list(todo_list)
    within("#todo_item_#{todo_item.id}") do
      click_link "Edit"
    end
    fill_in "Content", with: ""
    click_button "Save"
    expect(page).to_not have_content("Saved todo list item.")
    expect(page).to have_content("Content cannot be blank.")
    todo_item.reload
    expect(todo_item.content).to eq("Milk")
  end
end

Can someone please help?

Take a look at the content you expect to see, and take a look at the errors prohibiting the item from being saved, the two are not equal:

Expected:

expect(page).to have_content("Content cannot be blank.")

The error being rendered: "2 errors prohibited this todo item from being saved: Content can't be blank"

So try changing your spec to the following:

expect(page).to have_content("Content can't be blank")
