rspec-rails extends Rails’ built-in testing framework to support rspec
examples for requests, controllers, models, views, helpers, mailers and
routing. It is a thin framework around Rails own helpers and you can
check their documentation for help as well.
rspec-rails 6 supports Rails 6.1 to 7.0. For earlier versions of Rails, you should use rspec-rails-5 for Rails 5.2 and 6.0, rspec-rails-4 for Rails 5.x, and rspec-rails 3 for even older versions.
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', '~> 6.0.0' 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:
bundle exec rails generate rspec:install
This adds the spec directory and some skeleton files, including a .rspec file.
You can also customize the default spec path with
bundle exec rails generate rspec:install --default-path behaviour
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.
