Failing Test

I continue to see the following error message when I attempt to write the test. Looks like it's working for Jason.

1) Creating todo lists redirects to the todo list index page on success Failure/Error: click_link "New Todo list" TypeError: no implicit conversion of nil into String # ./spec/features/todo_lists/create_spec.rb:6:in `block (2 levels) in <top (required)>'

Code in create_spec.rb

require 'spec_helper'

describe "Creating todo lists" do
  it "redirects to the todo list index page on success" do
    visit "/todo_lists"
    click_link "New Todo list"
    expect(page).to have_content("New todo_list")

  end

end

After have_content there is text in quotes. Look at your application page. Copy the way you wrote New todo_list on the page and paste it between the quotes. If what is on the page is different than what is between the quotes, your test will fail. A capital letter in one place while the other has lowercase, for instance, is not identical.

Thanks Michelle.

I tested it out a couple times and made sure to copy and paste the text. I also tried to download the project files and get them to run. Saw the same error. I had rails previously installed on my machine, went back through the tutorial of installing with rbenv and now it appears to be working.

Not sure if it was something in how I set up the project or perhaps a user error that I fixed the second time around. Thanks for taking the time to answer my post!
