I'm always getting two errors when ever I run my test.

Hi, I'm always getting two errors when ever I run my test.

Here's my code below in create_rspec.rb, and then what the terminal returns:

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

If you need more of the backtrace for any of these deprecations to
identify where to make the necessary changes, you can configure
`config.raise_errors_for_deprecations!`, and it will turn the
deprecation warnings into errors, giving you the full backtrace.

The strange thing is that when I still go ahead and test the functionality by clicking "Create Todo list", I am able to successfully see the error messages written to the page.

Thanks!

My bet is that your page says "New Todo list" and your test says click_link "New Todo List". Just make the capitalization identical in both.

If you publish your view code or the link to github repo, it will be much easier to find the problem.
