如何设置Jenkins运行android单元测试？

Question

我最近在开发机器上安装了Jenkins，以帮助我了解持续集成/交付的工作方式。

我有一个基本的Android任务设置，它将构建我的应用程序，然后报告皮棉，PMD，Checkstyle，Findbugs和JUnit（业务逻辑）测试结果。

我还希望它运行android单元测试（那些需要仿真器才能运行的测试），请问如何设置呢？ 将'connectedAndroidTest'添加到要在构建期间运行的gradle命令列表中后，得到以下输出：

17:03:21 :app:connectedDebugAndroidTest FAILED
17:03:21 
17:03:21 FAILURE: Build failed with an exception.
17:03:21 
17:03:21 * What went wrong:
17:03:21 Execution failed for task ':app:connectedDebugAndroidTest'.
17:03:21 > com.android.builder.testing.api.DeviceException: No connected devices!
17:03:21 
17:03:21 * Try:
17:03:21 Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
17:03:21 
17:03:21 BUILD FAILED

这是预期的，因此我尝试从Android Studio启动模拟器并再次运行Jenkins构建，导致此错误：

我还尝试通过任务设置来设置仿真器。 我已经选中了“在构建过程中运行Android模拟器”选项。

运行现有模拟器的选项对我不起作用-我将其命名为我在Android Studio中创建的模拟器的AVD名称，在我的情况下为“ Nexus_5X_API_26”，并且在构建时出现以下错误：

17:26:07 FATAL: C:\Windows\system32\config\systemprofile\.android\avd\Nexus_5X_API_26.ini (The system cannot find the path specified)
17:26:07 java.io.FileNotFoundException: C:\Windows\system32\config\systemprofile\.android\avd\Nexus_5X_API_26.ini (The system cannot find the path specified)

因为我的模拟器在C：\\ Users \\ Zach.android \\ avd \\中，所以这很有意义。

我还尝试使用以下值运行具有在配置中指定的属性的仿真器：

Android OS version: android-26
Screen density: 420
Screen resolution: 1080x1920
Device locale: en_US
SD card size: <empty>
Target ABI: x86
Emulator name suffix: <empty>

我得到以下输出：

17:31:51 $ D:\Android\sdk/tools/android.bat list target
17:31:52 [android] The configured Android platform needs to be installed: android-26
17:31:52 $ D:\Android\sdk/tools/android.bat list target

17:31:54 or by setting the USE_SDK_WRAPPER environment variable)

这会导致Jenkins在控制台输出视图的最后一行上因忙碌指示器而永久挂起。 我被迫中止构建并在此时重启Jenkins，以使构建再次起作用。

那么，我在这里想念什么？ 为什么这对我来说如此困难！ 任何人都知道如何完成Android单元测试的运行->让模拟器开始在Jenkins上构建吗？

编辑 ：我将Jenkins更新为以“我”的身份运行，而不是本地系统帐户，这使我能够（尝试）使用现有的模拟器，而不是抱怨找不到它。 但是，现在尝试启动模拟器时出现此错误：

00:28:11 $ D:\Android\sdk/tools/android.bat list target
00:28:12 [android] Using Android SDK: D:\Android\sdk

所以我想这是目前的头号问题，有什么想法吗？

通过添加“ -engine auto”仿真器选项，我能够使它正常工作。
