Effective Testing with RSpec 3

Installation

Rails provides infrastructure for directly testing specific pieces of your application: models, views, controllers, and so on. It also supports tests that integrate multiple layers and acceptance tests that integrate all layers.

The rspec-rails gem adapts the Rails testing infrastructure for use from RSpec. To use it, add an entry like the following one to the :development and :test groups in your Gemfile:

A2-using-rspec-with-rails/01/rails_app/Gemfile

group :development, :test do
  gem 'rspec-rails', '~> 3.6'
end

Then, run bundle install to install rspec-rails. Finally, you can set your project up to use rspec-rails with the following command:

$ rails generate rspec:install
      create  .rspec
      create  spec
 create ...
