Karma? :thinking:

  • JavaScriptのテストランナー
  • ブラウザを起動してその上でJavaScriptのテストを実行する
  • ブラウザが起動するので見た目も確認できる
  • Developer Consoleでブレークポイント等の機能が使える
  • angular-cliはユニットテスト環境としてKarmaを自動でセットアップする

Karma駆動開発?

  • KarmaでUIロジックのテストもしつつ、見た目もそこで試行錯誤すると楽
  • アプリ上で再現するのが面倒な状況もテストを書けば再現が楽
  • そういうエッジケースのテストにもなって一石二鳥
  • 特定のテストケースだけ走らせることができるので繰り返しが早くできる
  • あくまでテスト環境なので、あまり複雑なことはしないほうが良さそう
