My steps for starting a new Rails Application

rails_setup.md

1. rails new <project_name> -d postgresql -T

• -T, [--skip-test], [--no-skip-test] # Skip test files
• -d, [--database=DATABASE] # Preconfigure for selected database (options: mysql/postgresql/sqlite3/oracle/sqlserver/jdbcmysql/jdbcsqlite3/jdbcpostgresql/jdbc)

2. In the Gemfile: group :development, :test do gem 'factory_bot_rails' gem 'rspec-rails' gem 'shoulda-matchers' end

group :development do gem 'simplecov', require: false end

3. Run $ bundle install rails generate rspec:install

4. In spec/rails_helper.rb Shoulda::Matchers.configure do |config| config.integrate do |with| with.test_framework :rspec with.library :rails end end

5. At the top of rails_helper require 'simplecov' SimpleCov.start

6. Docker Compose File
