Question

我尝试将单元测试结果打印在jenkins控制台中。但我不能这样做。我在想jenkins构建控制台无法打印qDebug。我试过它无法打印qdebug。但是std :: cout正在发挥作用。我该怎么办？

谢谢。我试过你说的。但它无法奏效。它给出了错误。错误：C3861：＆＃39; qInstallMsgHandler＆＃39;：未找到标识符

QT4版本：尝试像这样实现自己的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: %s\n", msg);
    //  break;
    //case QtCriticalMsg:
    //  fprintf(stderr, "Critical: %s\n", msg);
    //  break;
    //case QtFatalMsg:
    //  fprintf(stderr, "Fatal: %s\n", msg);
    //  abort();
    }
}

int main(int argc, char* argv[])
{
qInstallMsgHandler(MessageOutput);

QApplication App(argc, argv);

Testapp Updater;
Updater.doSomething();

return App.exec();
}

每个DebugMsg都被重定向到std :: cout。
