Question

我正在尝试使用qtest构建测试，以行使我的库，该库实现了包装QWebSocket的类。

QTest似乎将在“专用插槽：”下运行每个方法，并认为它是测试初始化，清除或测试用例。

但是，我也试图在localhost上建立一个服务器以连接到该服务器，并要求在侦听器接受连接并关闭等之后回调插槽。

QTest希望将这些回调视为测试用例，然后运行它们，这是不正确的。我怎么告诉它“这些是用于测试用例的插槽”和“这些是在其他地方使用的插槽？”

考虑以下测试代码：

#include <QCoreApplication>
#include <QtTest>
#include <QtWebSockets/qwebsocket.h>
#include <QtWebSockets/qwebsocketserver.h>
#include <string>

class qtwebstompclientimpl_tests : public QObject
{
    Q_OBJECT

public:
    qtwebstompclientimpl_tests();
    ~qtwebstompclientimpl_tests();

private slots:
    void initTestCase();
    void cleanupTestCase();
    void onAccept();                 // Wants to run these as test cases, but they are actually slots for QWebSocketServer
    void onAcceptError(QAbstractSocket::SocketError socketError);
    void onTextReceived(QString message);
    void onClientClosed();
    void test_case1();

private:
    QWebSocketServer * m_webSocketServer;
    QWebSocket * m_connectedWebsocketClient;
    bool m_errorOccurred;
    QString m_lastMessage;
};

qtwebstompclientimpl_tests::qtwebstompclientimpl_tests() {}

qtwebstompclientimpl_tests::~qtwebstompclientimpl_tests() {}

void qtwebstompclientimpl_tests::initTestCase()
{
    m_webSocketServer = new QWebSocketServer("Test Server", QWebSocketServer::NonSecureMode);
    if( !m_webSocketServer->listen(QHostAddress::Any, 5000) )
    {
        std::string errorMessage = m_webSocketServer->errorString().toStdString();
        throw std::runtime_error("Failed to setup test websocket server - Listen failed");
        connect(m_webSocketServer, &QWebSocketServer::newConnection, this, &qtwebstompclientimpl_tests::onAccept);
        connect(m_webSocketServer, &QWebSocketServer::acceptError, this, &qtwebstompclientimpl_tests::onAcceptError);
    }

    m_connectedWebsocketClient = nullptr;
    m_errorOccurred = false;
}

void qtwebstompclientimpl_tests::cleanupTestCase()
{
    if( m_connectedWebsocketClient )
    {
        delete m_connectedWebsocketClient;
    }
    delete m_testClient;
    delete m_webSocketServer;
}

void qtwebstompclientimpl_tests::onAccept()
{
    if(m_connectedWebsocketClient)
    {
        m_connectedWebsocketClient->close();
    }

    m_connectedWebsocketClient = m_webSocketServer->nextPendingConnection();

    connect(m_connectedWebsocketClient, &QWebSocket::textMessageReceived, this, &qtwebstompclientimpl_tests::onTextReceived);
    connect(m_connectedWebsocketClient, &QWebSocket::disconnected, this, &qtwebstompclientimpl_tests::onClientClosed);
}

void qtwebstompclientimpl_tests::onAcceptError(QAbstractSocket::SocketError socketError)
{
    m_errorOccurred = true;
}

void qtwebstompclientimpl_tests::onTextReceived(QString message)
{
    QWebSocket * client = qobject_cast<QWebSocket *>(sender());
    if(client == m_connectedWebsocketClient)
    {
        m_lastMessage = message;
    }
}

void qtwebstompclientimpl_tests::onClientClosed()
{
    QWebSocket * client = qobject_cast<QWebSocket *>(sender());
    if(client == m_connectedWebsocketClient)
    {
        m_connectedWebsocketClient->deleteLater();
    }
}

void qtwebstompclientimpl_tests::test_case1()
{
    QVERIFY(true);
}

QTEST_MAIN(qtwebstompclientimpl_tests)

通过组合使用

将其他广告位移至公共范围。 QTest似乎只能在专用范围内测试插槽。
使用qQwait，它允许处理其他事件，包括套接字的插槽。

qWait的副作用是使我的单元测试变得不必要地长，这是因为我们必须以足够高的间隔“猜测”以允许其他插槽进行处理。我们也很想睡觉，就像在睡觉时一样，必须确保它足够高，并在调试时将其启动，以便有足够的时间逐步执行代码。

在QTest中使用插槽-测试用例还是插槽？
