Could you tell me correct code?

This is my code. This error message was happened.

<My code> describe "Creating todo lists" do def create_todo_list(options={}) options[:title] ||= "My todo list" options[:description] ||= "This is my todo list."

visit "/todo_lists"
click_link "New Todo list"
expect(page).to have_content("New todo_list")

fill_in "Title", with: options[:title]
fill_in "Description", with: options[:description]
click_button "Create Todo list"

end

it "redirects to the todo list index page on success" do create_todo_list expect(page).to have_content("My todo list") end

it "displays an error when the todo list has no title" do create_todo_list(title: "") 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

It seems to be finding the content: "New Todo List Title Description Back"

Instead of: "New todo_list" like you have in your expectation.

Perhaps, your expectation should look like: expect(page).to have_content("New Todo List")
