タイトルは私が直面していることをかなり説明しています。私はいくつかの状態を持つReactコンポーネントをテストしようとしており、必要なものを得るためにコンポーネントに自分のストアを提供しようとしています。私は冗談を使用して、コンポーネントのテストを実行すると、私は次のエラーを取得する：Jestテスト実行時に `regeneratorRuntime`が定義されていません
ReferenceError: regeneratorRuntime is not defined
私はこれがbabel-polyfillまたはregenerator-runtime冗談に正しく適用されないことによって引き起こされることを読んでいくつかを決定しました。しかし、私はそれらのパッケージを両方インストールして、結果に変更を加えずに再実行しようとしました。 Jest Githubの問題ページ（Remove auto-inclusion of babel-polyfill #2755）を読んだ後、私はbabel-polyfillがバージョン19のJestに自動的に含まれていないことを知りました。そのパッケージを手動でインストールすると問題は解決するはずです。
