QTest and QEventLoop inside a library

Hi all,
inside a library I have code like:

Code:

QNetworkReply* AIDAW::getRequest(const QString& url){
    QEventLoop loop;
    QTimer timer;
 
    QNetworkRequest request(url);
    QNetworkReply *reply = this->network_manager->get(request);
 
    QObject::connect(reply, SIGNAL(finished()), &loop, SLOT(quit()));
    QObject::connect(&timer, SIGNAL(timeout()), &loop, SLOT(quit()));
 
    timer.start(TIMEOUT);
    loop.exec();
 
    if(timer.isActive() == false){
        //manage the timeout
    }
 
    return reply;
 
}

If I try to write a QTest Project using this library I get this error:

Code:

********* Start testing of MyProject *********

the main of the test project is managed by QTEST_MAIN(MyTestClass) macro
