如何设置Jenkins运行android单元测试？

我最近在我的开发机器上安装了Jenkins，以帮助我了解持续集成/交付的工作原理。

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

我还想运行android单元测试（需要模拟器运行的那些），如何设置它？在我将“connectedAndroidTest”添加到要在构建期间运行的gradle命令列表后，我得到以下输出：

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，所以我尝试从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模拟器。我已选中“在构建期间运行Android模拟器”选项。

运行现有模拟器的选项对我不起作用 - 我从我在Android Studio中创建的模拟器中给出了AVD名称，在我的案例中为“Nexus_5X_API_26”，我在构建时遇到以下错误：

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)

这是有道理的，因为我的模拟器位于C：\ Users \ Zach.android \ avd \。

我还尝试使用以下值运行我在配置中指定属性的模拟器：

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

导致Jenkins永远挂起，并在控制台输出视图的最后一行显示忙碌指示符。我被迫中止构建并在此时重新启动Jenkins，以便让构建再次工作。

那么，我在这里错过了什么？为什么这对我来说太难了！任何人都知道如何完成运行Android单元测试 - ＆gt;得到一个模拟器来启动Jenkins的构建？

编辑：我更新了Jenkins以“我”而不是本地系统帐户运行，并允许我（尝试）使用现有的模拟器，而不是抱怨无法找到它。但是，我现在在尝试启动模拟器时遇到此错误：

00:28:11 $ D:\Android\sdk/tools/android.bat list target

所以我猜这个现在是第一个问题，有什么想法吗？

1 个答案:

答案 0 :(得分：0)

我能够通过添加“-engine auto”模拟器选项来实现此功能。
