在测试用例中阅读qdebug?

在我的测试用例中,我想声明qDebug()的输出包含某个字符串。例如,这就是我的测试。请注意qdebug的“绑定到UDP端口34772”输出。我可以在我的测试函数中测试qdebug中是否存在子串34772吗?

********* Start testing of tst_NetSocket *********
Config: Using QTest library 4.8.6, Qt 4.8.6
PASS   : tst_NetSocket::initTestCase()
QDEBUG : tst_NetSocket::testBindToPortDefaultToMinAvailable() Bound to UDP port  34772 
FAIL!  : tst_NetSocket::testBindToPortDefaultToMinAvailable() 'socket->getCurrentPort() == port_should_be' returned FALSE. ()
   Loc: [test_net_socket.cpp(59)]
PASS   : tst_NetSocket::cleanupTestCase()
Totals: 5 passed, 1 failed, 0 skipped
********* Finished testing of tst_NetSocket *********

这是我的测试文件。我想在我的测试函数中添加一个QVERIFY()语句,用于检查子串34772的qDebug输出。

#include <QObject>
#include <QtTest/QtTest>
#include <unistd.h>
#include "net_socket.hpp"

class tst_NetSocket: public QObject
{
    Q_OBJECT

private slots:
    // ....
    void testBindToPortDefaultToMinAvailable();
};

// ... other tests removed for example ...

void tst_NetSocket::testBindToPortDefaultToMinAvailable()
{
    NetSocket * socket = new NetSocket();

    int port_should_be = (32768 + (getuid() % 4096)*4);
    if (socket->bindToPort()) {
        QVERIFY(socket->getCurrentPort() == port_should_be);
    }
}

QTEST_MAIN(tst_NetSocket)
#include "test_net_socket.moc"

使用QTest::ignoreMessage断言在测试代码中添加了某条消息:

// ...
int port_should_be = (32768 + (getuid() % 4096)*4);
QTest::ignoreMessage(QtDebugMsg, QString::fromLatin1("Bound to UDP port  %1").arg(port_should_be).toUtf8().constData());
// ...
