i copy the tutorial but these types of errors are so frustrating, which holds me back from learning Rails :(

From looking at your test-spec, I can see that the final 2 tests have the same content? I would delete the final test as it says testing no description but you have a description. See below an excerpt of your code.

    it "displays an error when the todo list has no description" do
      expect(TodoList.count).to eq(0)

      create_todo_list title: "Grocery list", description: ""

      expect(page).to have_content("error")
      expect(TodoList.count).to eq(0)

      visit "/todo_lists"
      expect(page).to_not have_content("Grocery list")
    end

    it "displays an error when the todo list has no description" do
      expect(TodoList.count).to eq(0)

      create_todo_list title: "Grocery list", description: "Food"

      expect(page).to have_content("error")
      expect(TodoList.count).to eq(0)

      visit "/todo_lists"
      expect(page).to_not have_content("Grocery list")
    end

See they are both the same test.

i go through the videos and then download the project files. removing it solved the problem, thanks a bunch!

Your welcome and anytime! Good luck for the rest of the course :)

Are you sure they don't fix it later in the video. As with TDD(Test Driven Development) you first write a failing test then add the code to make it pass. So if you carry on with the video it will add the code shortly

in the video it shows 0 failures but i get 1

Ok give me a minute I will have a look now
