Problèmes de tests unitaire avec QtCreator

Bonjour à tous,

Je travaille avec QtCreator 7.0.2 comme IDE basé sur Qt 6.2.3 (sous windows 10).

J’ai créé un projet de sous-répertoire, dans le quel j’ai créé :

• un projet Qt widgets Application ;
• un projet Auto test project.

Dans le projet Qt widgets Application

main.cpp

#include "mainwindow.h"

#include <QApplication>
#include <QLocale>
#include <QTranslator>

int main(int argc, char *argv[])
{
      QApplication a(argc, argv);

      QTranslator translator;
      const QStringList uiLanguages = QLocale::system().uiLanguages();
      for (const QString &locale : uiLanguages) {
            const QString baseName = "ConversionsProject_" + QLocale(locale).name();
            if (translator.load(":/i18n/" + baseName)) {
                  a.installTranslator(&translator);
                  break;
            }
      }
      MainWindow w;
      w.show();
      return a.exec();
}

      {
            listOfDecimalNumber.push_back(pow(2,i));
            //ActualNumber *= 2;
      }
      return listOfDecimalNumber;
}

Dans le projet Auto test project

void Test::test_getDecimalsNumbers()

      MainWindow fentP;
      std::list<int> listOfDecimalNumber({1,2,4,8,16,32,64,128,256});
      QCOMPARE(fentP.getDecimalsNumbers(9), listOfDecimalNumber);
}

void Test::test_lineEditBinaire()
{
      
}
Dans la fonction
void Test::test_getDecimalsNumbers()
{
      MainWindow fentP;
      std::list<int> listOfDecimalNumber({1,2,4,8,16,32,64,128,256});
      QCOMPARE(fentP.getDecimalsNumbers(9), listOfDecimalNumber);
}

J’ai pu tester la fonction

getDecimalsNumbers()

qui se trouve dans le fichier

mainwindow.h

(voir

Test::test_getDecimalsNumbers()

), mais je n’arrive pas à accéder aux objets graphiques qui se trouvent dans le fichier

mainwindow.ui

pour pouvoir faire des tests

Si quelqu’un a une idée s'il vous plaît.
Merci d’avance
