Description
The QmlTestRunner crashes when performing the following, UI related test:
import QtQuick 2.3 import QtTest 1.0 TestCase { name: "ModuleImportTest" id: parent function test_load_ZZZZZDeveloperView() { var item = createTemporaryQmlObject(" import QtQuick 2.0; import Governikus.DeveloperView 1.0; DeveloperView {} ", parent); item.destroy(); } }
The QmlTestRunner is invoked like this:
/home/governikus/workspace/JM_default_Review_Linux/Compiler/g++/build/test/qml/QmlTestRunner -platform offscreen -vs -nocrashhandler -input /home/governikus/workspace/JM_default_Review_Linux/Compiler/g++/source/test/qml/test_module_imports.qml -import /home/governikus/workspace/JM_default_Review_Linux/Compiler/g++/source/resources/qml -file-selector android
The cause of the crash is a null pointer dereference since there is no $DISPLAY in the environment:

The tested QML component can be viewed here: https://github.com/Governikus/AusweisApp2/blob/community/resources/qml/Governikus/DeveloperView/DeveloperView.qml
In Order to load the correct QML components, the QmlTestRunner is build with the not-yet-release file selector patch from change I556ad7211ed4a0881150686270a9a4e69f68d1ee .
