RSpec Test Failures (Capybara Error)

Neither of my tests are passing. I get the following:

Failures:

1) Creating todo lists redirects to the todo lists index page on success Failure/Error: click_button "Create Todo List" Capybara::ElementNotFound: Unable to find button "Create Todo List" # ./spec/features/todo_lists/create_spec.rb:11:in `block (2 levels) in <top (required)>'

2) Creating todo lists displays an error when the todo list has no title Failure/Error: click_button "Create Todo List" Capybara::ElementNotFound: Unable to find button "Create Todo List" # ./spec/features/todo_lists/create_spec.rb:25:in `block (2 levels) in <top (required)>'

My code:

require 'spec_helper'

describe "Creating todo lists" do
    it "redirects to the todo lists 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("Todo list was successfully created.")
    end

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

It looks like your button doesn't say "Create Todo List" verbatim. It's probably something like "Create Todo list" or "Create Todo_list" - run your server, navigate to that page and see what the button has on it. Underscores and capital/lowercase letters are all very important. Capybara (and programs in general) is very precise.

Duh. Silly me. Thanks. It was Create Todo list NOT Create Todo List.

I am experiencing the identical error and here is the code I have: 

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 "displays an error when the todo list has no title" 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: ""
    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
end

I've combed through the spec.rb sheet multiple times and have been unable to ID the potential bug. Any thoughts?

You have to show us more, preferably a link to the whole app.

You pushed some folder that contains two projects inside and I can't access todo project there.

Well another issue I'm having is how can I send you a link to the Sublime text file? I don't believe I know how to do that?...
