Rspec test fails for delete todo list

When I run Rspec for Deleting todo lists is successful when clicking the destroy link, I get the following error.

Failures:

  1) Deleting todo lists is successful when clicking the destroy link
     Failure/Error: expect(page).to_not have_content(todo_list.title)
       expected not to find text "Groceries" in "Todo list was successfully destroyed. Listing Todo Lists Title Description Groceries Grocery list. Show Edit Destroy Groceries Grocery list. Show Edit Destroy Groceries Grocery list. Show Edit Destroy Groceries Grocery list. Show Edit Destroy Groceries Grocery list. Show Edit Destroy Groceries Grocery list. Show Edit Destroy Groceries Grocery list. Show Edit Destroy Groceries Grocery list. Show Edit Destroy Groceries Grocery list. Show Edit Destroy Groceries Grocery list. Show Edit Destroy New Todo list"
     # ./spec/features/todo_lists/destroy_spec.rb:13:in `block (2 levels) in <top (required)>'

My code is as follows...

require 'spec_helper'

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

    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

Does anyone know why I am getting errors? I noticed that rspec thinks there are 10 todolists.

It is not obvious because the rspec error message shows the page text but not the HTML. It looks like there are ten remaining todo lists, and each is named "Groceries."

Try resetting your test database (bundle exec rake db:reset RAILS_ENV=test) and try it again. You can also look through your test log file to see what database transactions are occurring or failing.

It is very useful to have Capybara to save a screen shot on every error. Google "capybara save_and_show_page" to see how to set this up.

Good luck!
