Test Crash Because Of Fontfamilyalias

Redman

Hi,

I have a Qt test suite which reads some sort of configuration from a qml file in initTestCase().
Unfortunately when loading the qml file into a QQmlComponent I get 0xc0000005 when trying to resolve the fontFamilyAlias "Roboto" in QFontDatabasePrivate::resolveFontFamilyAlias.

void
TestSuite::initTestCase() {
   // Create QCoreApplication
   TestUtil::QtAppInstance::instance();
   // Create QQmlEngine
   m_engine.reset(new QQmlEngine());
   // Load config file
   m_qmlFile.reset(new QQmlComponent(m_engine.get(),
       QUrl("pathToQml))); <--- ERROR
   m_pAObj.reset(m_qmlFile->create());
}

I have other test suites where I do not read that qml file and it works fine.

I do use that fontpack in my application like this
main.cpp

   qint32 fontId = QFontDatabase::addApplicationFont(
       ":/font/RobotoCondensed-VariableFont_wght.ttf");
   QStringList fontList = QFontDatabase::applicationFontFamilies(fontId);

   QString family = fontList.first();
   QGuiApplication::setFont(QFont(family));

So, why does my test know anything about that font?

You should use a debugger to see where it really crashes and if you can reproduce it, create a minimal, compilable example so we can also take a look on it.
