Why am I getting this failure when I run bin/rake spec?

here is the error:

The semantics of `RSpec::Core::ExampleGroup.pending` are changing in RSpec 3.
In RSpec 2.x, it caused the example to be skipped. In RSpec 3, the example will
still be run but is expected to fail, and will be marked as a failure (rather
than as pending) if the example passes, just like how `pending` with a block
from within an example already works.

To keep the same skip semantics, change `pending` to `skip`.  Otherwise, if you
want the new RSpec 3 behavior, you can safely ignore this warning and continue
to upgrade to RSpec 3 without addressing it.

If you need more of the backtrace for any of these deprecations to
identify where to make the necessary changes, you can configure
`config.raise_errors_for_deprecations!`, and it will turn the
deprecation warnings into errors, giving you the full backtrace.

Hi Kaitlin,

You are getting a handful of deprecation warnings. Adding the line: c.expose_current_running_example_as :example to your spec helper will clear some up. Your failed test is looking for "New Todo List", but is finding "New todo_list". You need to change either your test, or your view. I would suggest the view since "New todo_list" doesn't give a good user experience. Also if you add "gem 'rspec-activemodel-mocks'" to your gem file under test: e.g.

group :test do
  gem 'capybara', '~> 2.1.0'
  gem "capybara-email", "~> 2.2.0"
  gem 'shoulda-matchers', '~> 2.6.0'
  gem 'rspec-activemodel-mocks'
end

Should get rid of your stub_model deprecation warning.

Neither one of these things fixed my errors unfortunately

I'm not quite sure why you get those errors, but I also had issues with the same command.

So, I checked the file spec/spec_helper.rb and noticed that I have a typo on 'capybara/rspec' because I've wrote capybara/rsspec, (notice the double s).

# This file is copied to spec/ when you run 'rails generate rspec:install'
ENV["RAILS_ENV"] ||= 'test'
require File.expand_path("../../config/environment", __FILE__)
require 'rspec/rails'
require 'rspec/autorun'
require 'capybara/rspec'

I hope this helps.
