Getting a failure in "displays item content the when a todo list has items", size is 1 instead of 2

Question

Here's my test:

    it "displays item content when a todo list has items" do
        todo_list.todo_items.create(content: "Milk")
        todo_list.todo_items.create(content: "Eggs")

        visit_todo_list(todo_list)

        expect(page.all("ul.todo_items li").size).to eq(2)

        within "ul.todo_items" do
            expect(page).to have_content("Milk")
            expect(page).to have_content("Eggs")
        end
    end

Here's the failure:

1) Viewing todo items displays item content when a todo list has items
     Failure/Error: expect(page.all("ul.todo_items li").size).to eq(2)

       expected: 2
            got: 1

       (compared using ==)
     # ./spec/features/todo_items/index_spec.rb:32:in `block (2 levels) in <top (required)>'

The line todo_list.todo_items.create(content: "Milk") doesn't get executed/isn't counted. Removed expect(page.all("ul.todo_items li").size).to eq(2) to see if it finds both items ("milk" and "eggs") - it does, so obviously it's created. Any ideas what's going on?

Found the culprit: typo in /todo_items/index.html.erb:

<ul class="todo_items"
  <% @todo_list.todo_items.each do |item| %>
  <li><%= item.content %></li>
  <% end %>
</ul>

instead of

<ul class="todo_items">
  <% @todo_list.todo_items.each do |item| %>
  <li><%= item.content %></li>
  <% end %>
</ul>
