こんばんは。

Azure DevOpsでUITestをやっているのですが、詰まってしまってどうしようもないので、ひとまずアウトプットしようと思って記事を書いています。

2021/12/2追記。バグは解消しました。詳細を追記します。

概要

Visual Studio EnterpriseでなくてもUITestができると聞いたので、boiler's GraphicsにUITestを導入してみました。C#テストプロジェクトでUITestを実現するにはWinAppDriverというソフトウェアをインストールする必要があるとのことなのです。

WinAppDriver のインストール

今回はWinAppDriverのReleaseページのv1.3 Release Candidate 1 (1.2.99)を選択しました。
インストーラーはWindowsApplicationDriver-1.2.99-win-x64.exeです。

WinAppDriverの実行

WinAppDriverをインストールしたら、C:\Program Files\Windows Application Driver\WinAppDriver.exeをダブルクリックして起動します。

↑この状態になったら放置します。

テストプロジェクトに(NuGetで)ライブラリをインストールする

またC#テストプロジェクトにNuGetパッケージマネージャーで、"Microsoft.WinAppDriver.Appium.WebDriver"のバージョン1.0.1-Previewをインストールします。プレビュー版なので、☑プレリリースを含めるにチェックを入れて下さい。

UITestを書く

そして、C#テストプロジェクトにUITestを書きますが、手始めにAppSession.csというUITest共通の基本クラスを作成します。ここでsessionなどを準備します。

UITest/AppSession.cs

using NUnit.Framework;
using OpenQA.Selenium.Appium.Windows;
using OpenQA.Selenium.Remote;
using System;
using System.IO;
using System.Reflection;

namespace boilersGraphics.Test.UITests
{
    public class AppSession
    {
        // Note: append /wd/hub to the URL if you're directing the test at Appium
        private const string WindowsApplicationDriverUrl = "http://127.0.0.1:4723";
        private static readonly string AppPath = Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), "boilersGraphics.exe");//"Microsoft.WindowsCalculator_8wekyb3d8bbwe!App";

        protected static WindowsDriver<WindowsElement> session;

        [SetUp]
        public static void Setup()
        {
            // Launch Calculator application if it is not yet launched
            if (session == null)
            {
                // Create a new session to bring up an instance of the Calculator application
                // Note: Multiple calculator windows (instances) share the same process Id
                DesiredCapabilities appCapabilities = new DesiredCapabilities();
                appCapabilities.SetCapability("app", AppPath);
                appCapabilities.SetCapability("deviceName", "WindowsPC");
                session = new WindowsDriver<WindowsElement>(new Uri(WindowsApplicationDriverUrl), appCapabilities);
                Assert.That(session, Is.Not.Null);

                // Set implicit timeout to 1.5 seconds to make element search to retry every 500 ms for at most three times

                session.Manage().Timeouts().ImplicitWait = TimeSpan.FromMinutes(1);

                session.Manage().Window.Maximize();
            }
        }

        [TearDown]
        public static void TearDown()
        {
            // Close the application and delete the session
            if (session != null)
            {
                session.Quit();
                session = null;
            }
        }
    }
}

※テスト安定化を図るために、WindowsDriverSessionでMaximize()して、テスト対象アプリのウィンドウを最大化しています。これをすることで、テスト対象アプリのウィンドウが最も手前に来てテストが安定します。

あとは、思う存分にUITestのコードを書くだけです。今回は(1)チェッカーパターンの出来損ないが収録されているxmlファイルを読み込んで、jpgファイルにエクスポートするのと、(2)単なる白背景のキャンパスをそのままjpgファイルにエクスポートする２つを実装してみます...。

下記ではライブラリとして、ログ出力のためにNLog等を使用しています。（なくてもおｋ！）

UITests/ExportTest.cs

using NLog;
using NUnit.Framework;
using OpenQA.Selenium;
using System.IO;
using System.Reflection;
using System.Threading;

namespace boilersGraphics.Test.UITests
{
    [TestFixture]
    public class ExportTest : AppSession
    {
        [Test]
        public void 真っ白なキャンパスをエクスポートする()
        {
            var dir = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
            var exportFilePath = $"{dir}\\ExportTest.jpg";

            try
            {
                session.FindElementByAccessibilityId("Export").Click();
                session.FindElementByAccessibilityId("ExportFileName").SendKeys(exportFilePath);
                session.FindElementByAccessibilityId("PerformExport").Click();
                Thread.Sleep(1000);
                LogManager.GetCurrentClassLogger().Info(exportFilePath);
                Assert.That(File.Exists(exportFilePath), Is.EqualTo(true));
            }
            finally
            {
                File.Delete(exportFilePath);
            }
        }

        [Test]
        public void チェッカーパターンを読み込んでエクスポートする()
        {
            LogManager.GetCurrentClassLogger().Info("A");
            var dir = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
            var loadFilePath = $"{dir}\\XmlFiles\\checker_pattern.xml";
            var exportFilePath = $"{dir}\\ExportTest2.jpg";

            try
            {
                LogManager.GetCurrentClassLogger().Info("B");
                session.FindElementByAccessibilityId("Load").Click();
                LogManager.GetCurrentClassLogger().Info("C");
                session.FindElementByAccessibilityId("1").Click();
                LogManager.GetCurrentClassLogger().Info("D");
                session.Keyboard.SendKeys(Keys.Alt + "N" + Keys.Alt);
                LogManager.GetCurrentClassLogger().Info("E");
                session.Keyboard.SendKeys(Keys.Alt + "N" + Keys.Alt);
                LogManager.GetCurrentClassLogger().Info("F");
                session.FindElementByAccessibilityId("1148").SendKeys(loadFilePath);
                LogManager.GetCurrentClassLogger().Info("G");
                session.FindElementByAccessibilityId("1").Click();

                LogManager.GetCurrentClassLogger().Info("H");
                Thread.Sleep(1000);


                session.FindElementByAccessibilityId("Export").Click();
                LogManager.GetCurrentClassLogger().Info("I");
                Thread.Sleep(1000);
                session.FindElementByAccessibilityId("ExportFileName").SendKeys(exportFilePath);
                LogManager.GetCurrentClassLogger().Info("J");
                session.FindElementByAccessibilityId("PerformExport").Click();
                LogManager.GetCurrentClassLogger().Info("K");
                Thread.Sleep(1000);
                LogManager.GetCurrentClassLogger().Info("L");
                Assert.That(File.Exists(exportFilePath), Is.EqualTo(true));
                LogManager.GetCurrentClassLogger().Info("M");
            }
            finally
            {
                LogManager.GetCurrentClassLogger().Info("N");
                File.Delete(exportFilePath);
                LogManager.GetCurrentClassLogger().Info("O");
            }
        }
    }
}

ローカル環境でテスト実行

あと注意点なのですが、Windowsの設定で英語キーボードじゃないと""が文字化けして"]"になってしまう問題があります。これは、テストを実行する前にWindowsキー+Spaceキーでキーボードレイアウトを英語（米国）にする必要があります。この辺将来のアップデートで日本語キーボードも使えるようにして欲しぃ...。

テストを書いたら、ローカルでテストしてみます。ローカルではテストはすんなり通ると思います。

↑ちょっと画面端が切れてますがご了承下さい。ScreenToGifだとフルスクリーンで録画できないんです...。
でも、こうして自動でUITestが動いていることがわかると思います。

Azure DevOps(CIサーバー）でテスト実行

さて、出来上がったUITestはローカル環境で検証しましたが、これをクラウドのCI環境で自動で検証させたいという要望が上がってきました。試しにAzure DevOpsでUITestを実行させてみましょう。

アドオンインストール

Azure DevOpsでWinAppDriverを実行するにはアドオンをインストールする必要があります。

azure-pipelines.ymlに追記

次に、azure-pipelines.ymlにWinAppDriverの起動タスクと終了タスクを追記する必要があります。

ここで重要なのはTestを実行しているタスクの前後にWinAppDriverの開始タスクと終了タスクを挿入する必要があるということです。

WinAppDriverの開始タスクではAgentResolutionとして'1080p'を指定します。（これ重要らしい）

テストが失敗してしまいました。
ログには以下のように出力されています。

A

C
D
E
F
G
H
I
N
O

処理ABCDEFGHIまでは順調に実行できているようです。
処理JKLMが実行できていない。Jで例外が飛んだか？
処理NOはfinally句なので実行されてますね。

ちなみにCloseの方のWinAppDriverタスクを見てみると、WinAppDriverのログが出力されています。

ここでtimeoutsになっているようです。

該当箇所はExportFileName（エクスポートウィンドウのFileName欄）を探している時にTimeoutになっているようです。

session.FindElementByAccessibilityId("ExportFileName").SendKeys(exportFilePath);

これどうしたらいいんだろう...。

Azure DevOpsにおけるデバッグ手法 (2021/12/02追記)

Azure DevOpsにおいてデバッグする時に必須となる技術は2つあります。一つはログです。これはNLogなどの外部ライブラリを使えば簡単ですね。特筆すべきことはないです。

もう一つはスクリーンショットを撮ることです。WinAppDriverでは以下のようにしてスクリーンショットを撮ることができます。

session.GetScreenshot().SaveAsFile($"{AppDomain.CurrentDomain.BaseDirectory}\\filename.png");

撮ったスクリーンショットをAzure DevOps上でどのように確認するのかという問題があります。これはNUnitに実装されているTestContext.AddTestAttachmentメソッドを使うことで、Azure Pipelineに「このファイルはテストのアタッチメントですよー」というような感じで伝えることができます。

//Azure Pipelineにアタッチメントの存在を教える
TestContext.AddTestAttachment($"{AppDomain.CurrentDomain.BaseDirectory}\\{filename}");

これを行うと、以下のようにTestタブの中のテストケースを開き、さらにAttachmentsタブを開くと、AddTestAttachmentメソッドに渡したファイルが列挙されていますね。これをクリックすると、右側にプレビューすることができます。また、More Optionsからアタッチメントをダウンロードすることもできます。

この機能に気づき、利用しようとした時のコミットで、各処理が終わる毎にスクリーンショットを撮ろうとしましたが、スクリーンショットを撮り始めた瞬間から、テストがパスするようになりました。timeout問題はスクリーンショットを撮る行為により、解決に至りました...。

原因を調査したところ、timeoutする瞬間のスクリーンショットは以下のようになっています。閉じているはずのOpenダイアログが開きっぱなしになっているではありませんか！！！また開いているはずのエクスポートダイアログがOpenダイアログがモーダルで開いていることで開けなかったということがわかります。そりゃエクスポートダイアログの中のExportFileNameが見つからないはずですわ。これの対処を行ったところ、テストはパスしました。

無事パイプラインは成功しました。やったね✌✌✌
↓以下のリンクは成功したパイプラインです。

ソースコード

ブランチは develop です。

まとめ

というわけで、Azure DevOps & WinAppDriver の記事を書いてみましたよっと。
何か参考になれば幸いです。

コンピュータビジョンツールも開発しています。こちらは最近ご無沙汰ですが、たまにメンテしてます。スクリーンショット機能が便利でよく使ってますね。
