Appium-超时且从未收到命令的回应

我们有Jenkins使用Appium启动UI测试,但结果是错误:

remote stacktrace: UnknownError: An unknown server-side error occurred
while processing the command. Original error: Error getting AVD with
retry. Original error: Condition unmet after 60063 ms. Timing out.

当Appium的任务正在运行时,没有找到emulator进程。 Appium的输出也显示:

[debug] [ADB] Emulator Nexus_5X_API_26 not running
[debug] [ADB] Trying to find Nexus_5X_API_26 emulator
[debug] [ADB] Getting connected emulators
[debug] [ADB] Getting connected devices...
[debug] [ADB] 0 device(s) connected
[debug] [ADB] 0 emulator(s) connected

好的,我看到设备没有启动,这是导致“超时”错误的原因。

但是为什么Appium无法启动?

我能够获得emulator可执行文件,而正在执行Appium任务的詹金(Jenkin)的工作可以看到该设备:

[Pipeline] sh
+ avdmanager list avd
...
    Name: Nexus_5X_API_26
  Device: Nexus 5X (Google)
    Path: /home/user/.android/avd/Nexus_5X_API_26.avd
  Target: Google Play (Google Inc.)
          Based on: Android 8.0 (Oreo) Tag/ABI: google_apis_playstore/x86
    Skin: 1080x1920
  Sdcard: 100 MB

    Name: test
    Path: /home/user/.android/avd/test.avd
  Target: Google APIs (Google Inc.)
          Based on: Android 7.1.1 (Nougat) Tag/ABI: google_apis/x86
[Pipeline] sh
+ emulator -list-avds
Nexus_5X_API_26
test

如果我仅通过运行来手动启动设备:

/android/Android/sdk/emulator/emulator -avd Nexus_5X_API_26

然后触发詹金的工作-我有另一个错误:

...
[ADB] Using adb from /android/Android/sdk/platform-tools/adb

有什么想法吗?

甚至无法通过“ appium从来没有收到命令的响应”请求来搜索任何内容...

此外,我无法在工作站的笔记本电脑上重现此问题-一切运行正常。

UPD 属性是:

    </properties>
</profile>

UPD 2 (不确定如何操作)-但如果手动运行emulator则无法正常工作。 但是从Appium本身启动emulator还是有问题。

在其日志中发现了奇怪的错误:

[ADB] [AVD OUTPUT] Fatal: QXcbConnection: Could not connect to display  ((null):0, (null))
[ADB] [AVD OUTPUT] INFO: QtLogger.cpp:66: Fatal: QXcbConnection: Could not connect to display  ((null):0, (null))
[ADB] Emulator avd Nexus_5X_API_26 exited with code null, signal SIGABRT

目前还不能出于某种原因使用Google进行搜索,但这似乎是主要问题-尽管存在$DISPLAY的问题。

1 个答案:

答案 0 :(得分:1)

我能够在模拟器上启动并运行测试,而没有任何问题。在设置驱动程序时,我会使用以下三个功能以及其他功能。

  1. avd:AVD的名称
  2. avdLaunchTimeout:等待模拟器启动超时。
  3. avdReadyTimeout:超时,等待仿真器准备就绪。

尝试使用这些功能,您应该会很好。

还要检查是否有针对Android SDK和模拟器的任何更新。如果有可用的更新,则最好进行更新。
