Capybara::ElementNotFound when doing rspec test for deletion

Jason Seifer

Code:

require 'spec_helper'

describe "Deleting todo lists"  do
    let!(:todo_list) {TodoList.create(title: "Groceries", description: "Grocery list.")}

    let!(:todo_list) {TodoList.create(title: "", description: "")}
    it "is successful when clicking the destroy link" do
        visit "/todo_lists"

        within "#todo_list_#{todo_list.id}" do
            click_link "Destroy"
        end

        expect(page).to_not have_content(todo_list.title)
        expect(TodoList.count).to eq(0)
    end
end
