1. Create a new project



rails new rspec-test-app -d postgresql
cd rspec-test-app
rails db:create
rails s

2. Install gems



group :development, :test do
  gem 'rspec-rails', '~> 6.1.0'
  gem 'factory_bot_rails'
  gem 'faker'
end

3. Run below commands



bundle install
rails g rspec:install

4. Configure factory bot

Create spec/support/factory_bot.rb file then copy & paste below code



# spec/support/factory_bot.rb
require 'rails_helper'

RSpec.configure do |config|
    config.include FactoryBot::Syntax::Methods
end

Almost done. Now generate the user model



rails generate model User email:string password:string
rails db:migrate

It will generate following files for us:



invoke  active_record
create  db/migrate/20231130055533_create_users.rb
create  app/models/user.rb
invoke  rspec
create  spec/models/user_spec.rb
invoke  factory_bot
create  spec/factories/users.rb

Now run the below command and the watch the output
rspec
