[Interest] Printing QObject-derived classes on QCOMPARE failure

[Mitch Curtis]

Is it possible to have QCOMPARE call the operator<< overload for my custom QObject-derived class upon failure?

The following test only prints:

FAIL!  : Untitled1Test::testCase1() Compared pointers are not the same
   Loc: [../untitled1/tst_untitled1test.cpp(44)]

Code:

    #include <QDebug>
    #include <QString>
    #include <QtTest>
    
    class MyObject : public QObject
    {
        Q_OBJECT
    
    public:
        MyObject() {}
    
    private:
        // ...
    };
    
    QDebug operator<<(QDebug debug, const MyObject *myObject)
    {
        debug.nospace() << "(MyObject objectName=" << myObject->objectName()
            << ", other MyObject-specific stuff...)";
        return debug.space();
    }
    
    class Untitled1Test : public QObject
    {
        Q_OBJECT
    
    public:
        Untitled1Test();
    
    private Q_SLOTS:
        void testCase1();
    };
    
    Untitled1Test::Untitled1Test()
    {
        qRegisterMetaType<MyObject*>();
    }
    
    void Untitled1Test::testCase1()
    {
        MyObject object1;
        MyObject object2;
        QCOMPARE(&object1, &object2);
    }
    
    QTEST_APPLESS_MAIN(Untitled1Test)
    
    #include "tst_untitled1test.moc"

Cheers.
