I get a "Deprecation Warning" when running test on Ruby app

Hi there, when I run any test on ruby I get the following Deprecation Warnings which I have not idea what to do with as I'm fairly new to programing in general. I'm using VM:

treehouse:~/projects/odot (master *) $ bin/rspec spec/features/todo_lists/edit_spec.rb .

Deprecation Warnings:


RSpec::Core::ExampleGroup#example is deprecated and will be removed in RSpec 3. There are a few options for what you can use instead:

  • rspec-core's DSL methods (it, before, after, let, subject, etc) now yield the example as a block argument, and that is the recommended way to access the current example from those contexts.
  • The current example is now exposed via RSpec.current_example, which is accessible from any context.
  • If you can't update the code at this call site (e.g. because it is in an extension gem), you can use this snippet to continue making this method available in RSpec 2.99 and RSpec 3:

    RSpec.configure do |c| c.expose_current_running_example_as :example end

(Called from /home/treehouse/.rbenv/versions/2.0.0-p353/lib/ruby/gems/2.0.0/gems/capybara-2.1.0/lib/capybara/rspec.rb:20:in `block (2 levels) in <top (required)>')

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.

What you need to do is add the needed line to the application.rb inside Module "projectname".

Here how my file looks like (entered line is the third inside end.)

require File.expand_path('../boot', __FILE__)

require 'rails/all'

# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(:default, Rails.env)

module Odot
  class Application < Rails::Application
    # Settings in config/environments/* take precedence over those specified here.
    # Application configuration should go into files in config/initializers
    # -- all .rb files in that directory are automatically loaded.

    # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone.
    # Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC.
    # config.time_zone = 'Central Time (US & Canada)'

    # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded.
    # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]
    # config.i18n.default_locale = :de

    # In order to fix the depreciation error, RSpec::Core::ExampleGroup#example
    RSpec.configure do |c|
      c.expose_current_running_example_as :example
    end
  end
end

yes, so just add the following in the spec_helper.rb file. you can paste it to the end. this is directly from the deprecation warning. and it works!

RSpec.configure do |c| c.expose_current_running_example_as :example end
