ruby
group :development, :test do
  gem 'rspec-rails', '~> 5.0'
end

bash
rails generate rspec:install

ruby
# spec/controllers/users_controller_spec.rb
require 'rails_helper'
RSpec.describe UsersController, type: :controller do
  describe 'POST #create' do
    it 'redirects to the user page' do
      post :create
      expect(response).to redirect_to(user_path(assigns(:user)))
