rspec-rails extends Rails' built-in testing framework to support rspec examples for requests, controllers, models, views, helpers, mailers and routing.
rspec-rails 3 supports Rails 3.x and 4.x. For earlier versions of Rails, you need rspec-rails 1. For Rails 5.x, make sure you are using rspec-rails 3.5.0 or newer.
gem install rspec-rails
This installs the following gems:
rspec rspec-core rspec-expectations rspec-mocks rspec-rails
Add rspec-rails to the :test and :development groups in the Gemfile:
group :test, :development do gem 'rspec-rails', '~> 3.0.0' end
It needs to be in the :development group to expose generators and rake tasks without having to type RAILS_ENV=test.
Now you can run:
script/rails generate rspec:install
This adds the spec directory and some skeleton files, including a .rspec file.
The documentation for rspec-rails is a work in progress. We'll be adding Cucumber features over time, and clarifying existing ones. If you have specific features you'd like to see added, find the existing documentation incomplete or confusing, or, better yet, wish to write a missing Cucumber feature yourself, please submit an issue or a pull request.
