Selenium GUIなしでUbuntityサーバー16.04でJenkins経由でテスト実行（CLIのみ） - ヘッドモード

Question

私はJenkins経由でSelenium Automation Testingをやっています。

私のPCにJenkinsセットアップを実行し、Mavenプロジェクトとしてテストを実行しました。問題なく動作します。

JenkinsはGUIなしでUbuntuサーバーにセットアップされています（CLIのみ）。

• は、私は、変数設定Ubuntサーバー上でも

• ジェンキンス

  のグローバルプロパティに設定しジェンキンス

• でDISPLAY:0を追加プラグインXvfbをインストールした

  root@jenkins:~# echo $DISPLAY :0 
  

だから私がセレニウムscriを走らせるときpts via Jenkins次のエラーが表示されます。

誰でも私にこの問題の解決方法を教えてください。

Answer 1

それは根本的な原因は、独自のコードから来ているになります。

testCases.LoginTest.runBrowser -> utility.Utility.startRecording -> java.awt.Toolkit.getDefaultToolkit

utility.Utility.startRecordingにjava.awt.Toolkitへの依存性を削除し、それが失敗してはいけません。

Answer 2

私は同様の問題に直面しました。私はルートとしてサーバにログインしてそれを解決し、以下のコマンドを実行することができます。

Answer 3

私は自分のコードでコメントしていますが、今はビデオ録画（startRecording）を表示する機能を使用していません。 here参照してくださいhere
