尝试在没有监视器的MacOS Mini上运行Robotium
UI测试时，我首先遇到了此问题。我添加了Robotium代码来测试屏幕上的UI点击，因为我们想在回归测试中添加一些UI自动化。我在Jenkins服务器上收到的错误是当solo.clickInList（X）运行时：

junit.framework.AssertionFailedError: AbsListView is not found!
     [exec]     at com.jayway.android.robotium.solo.Waiter.waitForAndGetView(Waiter.java:492)
     [exec]     at com.jayway.android.robotium.solo.Clicker.clickInList(Clicker.java:406)
     [exec]     at com.jayway.android.robotium.solo.Clicker.clickInList(Clicker.java:388)
     [exec]     at com.jayway.android.robotium.solo.Solo.clickInList(Solo.java:1081)
     [exec]     at com.cars.android.robotium.TestApplication.testSearch(TestApplication.java:29)

我发现Jenkins需要Xvnc插件来伪造UI，以便仿真器可以使用它。确保在特定作业中选中“显示仿真器窗口”。现在，我当前收到此错误。

/Applications/RealVNC/VNC\ Server.app :$DISPLAY_NUMBER -localhost -geometry 1280x1024 -depth 24 -SecurityTypes None

我现在在詹金斯遇到这个错误
