We have Appimum tests running on a virtual device. But the problem is that the emulator's device won't start.

I'm pretty sure it's something with Android or Qt or Ubuntu itself.

In Appimu's output I found next error:

[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

The $DISPLAY is obviously set with value like :0.0 but even if I'm running tests from a terminal on this box via its monitor - I have this error.

Any suggestions? Trying to google the second day - still no ideas...

Unfortunately, I can't reproduce this issue on my work laptop - all works just fine.

adb:

$ adb --version Android Debug Bridge version 1.0.40 Version 4986621 Installed as /android/Android/sdk/platform-tools/adb

Appium:

$ appium --version 1.9.1

OS:

$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 16.04.5 LTS

All works fine if start emulator manually and run tests after.

  • Sorry, but development-related questions are off-topic because this site focuses on the end-user part. Since you can run the emulator manually, I'm afraid there's little that non-devs can help since they don't normally use Appium (automated testing framework). Stack Overflow is the more suitable site for the programming-related question, and you seem to have posted the question on there. – Andrew T. Dec 15 '18 at 14:48
