RSpecでtravel_toを使ってみた

Last updated at Posted at 2022-12-18

はじめに

ポートフォリオの作成で初めてtravel_toを使ったので記事にしました。

タイムゾーンを変更する

時間の変化を分かりやすくするため、タイムゾーンを日本に設定します。

config/application.rb
class Application < Rails::Application
  config.time_zone = 'Tokyo'
end

travel_to

putsで時間を表示させると、タイムスタンプが変わっていることが分かります。

spec/system/posts_spec.rb
  describe 'travel_toを使ってみた' do
    it '24時間前、現在、24時間後' do
      travel_to Time.zone.now.yesterday do
        puts Time.zone.now
      end
      puts Time.zone.now
      travel_to Time.zone.now.tomorrow do
        puts Time.zone.now
      end
    end
  end
結果
