railsプロジェクトを始めるときの流れ

新しくプロジェクトをつくろうとした時に思った事

newとか必要なgemとか忘れてて最小構成を調べ直した・・・

ということで備忘録としてまとめておきます

やりたいこと

• DBはmysql
• testはrspec
• テストを便利にするツールは最初から組み込む
• travis ciが動くようにする

プロジェクトを作成する

testはrspecで行うためにtest::unitを組み込まない

rails new srvadmin --skip-test-unit -d mysql

新しいアプリが作成されました。

gemに使うプラグインをインストールする

rspec等のテスト系で使うやつを予めインストールします
gemfileに以下を追加

group :development, :test do
  gem 'rspec-rails'
  gem 'capybara'
  gem 'spork-rails'
  gem 'guard-spork'
  gem 'childprocess' 
end

group :test do
  gem 'selenium-webdriver', '2.35.1'
end

プラグイン追加

bundle install

Rspec準備

rails generate rspec:install

      create  .rspec
      create  spec
      create  spec/spec_helper.rb
      create  spec/rails_helper.rb

Travis Ci準備

アプリのhomeディレクトリに.travis.ymlを準備する

travis.yml

language: ruby
rvm:
  - 2.1.0
gemfile:
  - Gemfile
env:
  - DB=mysql
before_script:
  - "cp config/database_travis.yml config/database.yml"
script:
  - bundle install --standalone --clean
  - RAILS_ENV=test bundle exec rake --trace db:create
  - RAILS_ENV=test bundle exec rake --trace db:migrate
  - bundle exec rake db:test:prepare
  - bundle exec rspec spec/

travisciが動いた時用のdatabase_travis.ymlも準備する

conifg/database_travis.yml

default: &default
  adapter: mysql2
  encoding: utf8
  pool: 5
  username: root
  password:
  host: localhost

development:
  <<: *default
  database: srvadmin_development

test:$
  <<: *default
  database: srvadmin_test

production:
  <<: *default
  database: srvadmin_production
  username: srvadmin
  password: <%= ENV['SRVADMIN_DATABASE_PASSWORD'] %>

database.ymlはデフォルト
　
　
guardやsporkの設定等もありますが
とりあえずここまでがアプリ初期設定とします。

この変は１回目のテストをする時にまとめるか、随時追記する。
