如何在jenkins控制台看到qDebug和单元测试宏(QCOMPARE等)的结果

Question

我尝试在jenkins控制台中打印单元测试结果。但我做不到。我认为jenkins构建控制台不能打印qDebug。我试了一下，它不能打印qdebug。但是std::cout正在工作。我该如何继续?

谢谢。我试过你说的。但它不能工作。它会产生误差。错误:C3861: 'qInstallMsgHandler':标识符未找到

QT4版本:尝试像这样实现您自己的Messagehandler:

void MessageOutput(QtMsgType type, const char* msg)
{
    //in this function, you can write the message to any stream!
    switch (type) {
      case QtDebugMsg:
        std::cout << msg << ::std::endl;
        break;
    //case QtWarningMsg:
    //  fprintf(stderr, "Warning: %sn", msg);
    //  break;
    //case QtCriticalMsg:
    //  fprintf(stderr, "Critical: %sn", msg);
    //  break;
    //case QtFatalMsg:
    //  fprintf(stderr, "Fatal: %sn", msg);
    //  abort();
    }
}
int main(int argc, char* argv[])
{
qInstallMsgHandler(MessageOutput);
QApplication App(argc, argv);
Testapp Updater;
Updater.doSomething();
return App.exec();
}

每个DebugMsg被重定向到std::cout。

这里的QT5示例相同
