Chrome固有の機能
これらは、Google Chromeブラウザに特有の機能と機能です。
これらは、Google Chromeブラウザに特有の機能と機能です。 デフォルトでは、Selenium 4はChrome v75以上と互換性があります。Chromeブラウザのバージョンとchromedriverのバージョンは、メジャーバージョンが一致する必要があることに注意してください。
Options
すべてのブラウザに共通する機能は オプション ページに記載されています。
ChromeおよびChromiumに特有の機能は、Googleの Capabilities & ChromeOptionsのページにドキュメントされています。
基本的に定義されたオプションでChromeセッションを開始する場合は、次のようになります：

});引数を除外する
Chrome はさまざまな引数を追加します。
これらの引数を追加したくない場合は、それらを excludeSwitches に渡します。
一般的な例は、ポップアップブロッカーをオンに設定することです。
デフォルトの引数の完全なリストは、 Chromium Source Codeから解析できます。
オプションに除外された引数を設定します。

ログ出力
ドライバーログを取得することは、問題のデバッグに役立ちます。Serviceクラスを使用すると、ログの出力先を指定できます。ユーザーがどこかにログを指示しない限り、ログ出力は無視されます。
ファイル出力

ログレベル
利用可能なログレベルは6つあります：ALL, DEBUG, INFO, WARNING, SEVERE, そして OFF。--verbose は --log-level=ALL と同等であり、--silent は --log-level=OFFと同等であることに注意してください。このため、この例ではログレベルを一般的に設定しています：

ログファイル機能
ファイルにログを記録する際にのみ利用できる2つの機能があります：
- ログの追加
- 読みやすいタイムスタンプ
これらを使用するには、ログパスとログレベルも明示的に指定する必要があります。ログ出力はプロセスではなくドライバーによって管理されるため、若干の違いが見られる場合があります。

ビルドチェックの無効化
ChromedriverとChromeブラウザのバージョンは一致する必要があり、一致しない場合、ドライバーはエラーを返します。ビルドチェックを無効にすると、任意のバージョンのChromeでドライバーを強制的に使用できます。ただし、これはサポートされていない機能であり、バグは調査されません。
