QWarn in qtest does not print anything



  • Probably a trivial error, I just don't know what it is. Searched google, but couldn't find anything relevant (lots of closed bugs though).

    I use Fedora 21, Qt5.4 and Qml 2, and I use QtTest. It all seems to work together fine, but my QWARN never prints anything, neither do I get messages from the Qt system that uses qwarn.

    I tried including <QDebug> to no avail.

    Does anyone know how to get QWARN to work?

    Hi,

    Without any code it's pretty much Crystal Ball debugging. Can you share your code ?



  • Hmm, bummer, I smashed my crystal ball ..... xD

    Okee, adding a sample from the code (would be a bit much to show everything, and probably not helpful). The QWARN you see here, compiles, but shows nothing. My suspicion is it is a macro that was commented unless something is defined.

    @
    #include <QtQml>

    #include "testport.h"
    #include "utils.h"

    TestPort::TestPort(QObject *parent) : QObject(parent)
    {

    }

    TestPort::~TestPort()
    {

    }

    /**

    • @brief TestPort::testPortCreation A simple test for creating a Port.
    • No further test necessary: QML takes care of all
      */
      void TestPort::testPortCreation() {
      model::Utils::registreModel();
      QQmlEngine engine;
      QQmlComponent component(&engine, QUrl("qrc:testport_1.qml"));
      model::Port *port = qobject_cast<model::Port *>(component.create());
      if (port) {
      QCOMPARE(port->name(), QString("testport1"));
      QCOMPARE(port->rdy(), QString("rdy1"));
      QCOMPARE(port->compName(), QString("compName1"));
      } else {
      QWARN("Creation of Port not successful. Recheck qml and qrc files.");
      QVERIFY(false);
      }

    }
    @

    Might be a silly question but are you sure that you are passing by the else case ?



  • Yep, completely. I have now added a std::cout << of component.errors() (broken down into strings) and finally got the error message. Still, the QWARN is silent.
