背景と修正の概要

こちらのgemを組み込んだ形でDecidimインスタンスのテストを実行すると、以下のような警告が出るようでした。

現在の状況

GitHub Actionsだと以下のようになります。

https://github.com/codeforjapan/decidim-cfj/actions/runs/13110282893/job/36572494144#step:13:61

確認環境

• 発生バージョン: decidim-cfj: (rev. a24919489eb675eb445358379d4eb7002a9200af) + omniauth-cityos-dcp tag: v1.3.0 (rev. 0fd1f02e17f0444d798cc5aff4fd8fadbc4a8313)
• 発生環境（ブラウザ、バージョン、OSなど）: Mac Sequoia, rspec / ubuntu-latest, rspec

確認手順

decidim-cfjをclone + bundle installした後、以下を実行すると出るはずです。

$ bundle exec rspec ./spec/system/comment_sort_spec.rb

修正する内容

• omniauth-cityos-dcpのどこか(おそらくlib/omniauth/cityos_dcp_login/engine.rbのinitializer等)に以下を追加すると出なくなるはずです

Decidim.icons.register(name: "facebook", icon: "facebook-fill", category: "system", description: "", engine: :core)
Decidim.icons.register(name: "x", icon: "x-fill", category: "system", description: "", engine: :core)
Decidim.icons.register(name: "google", icon: "google-fill", category: "system", description: "", engine: :core)

これはremixiconの名前がfoo-fillやfoo-lineのような命名になっているため、それに合わせる必要があるのでした。
例: https://remixicon.com/icon/google-fill

修正確認の手順と期待する結果

• bundle exec rspec ./spec/system/comment_sort_spec.rbを実行しても上記の警告が出なくなる
