便捷的使用QtTest进行批量单元测试

QTestRunner类用于管理被测试类对象，便于进行单元测试：

代码如下：

qtestrunner.h

#ifndef TESTRUNNER_H#define TESTRUNNER_H#include <QList>#include <QTimer>#include <QCoreApplication>#include <QtTest>/*Taken from https://stackoverflow.com/questions/1524390/what-unit-testing-framework-should-i-use-for-qtBEWARE: there are some concerns doing so, see  https://bugreports.qt.io/browse/QTBUG-23067*/class TestRunner : public QObject{    Q_OBJECTpublic:    TestRunner() : m_overallResult(0)    {        QDir dir;        if (!dir.exists(mTestLogFolder))        {            if (!dir.mkdir(mTestLogFolder))                qFatal("Cannot create folder %s", mTestLogFolder);        }    }    void addTest(QObject * test)    {        test->setParent(this);        m_tests.append(test);    }    bool runTests(int argc, char * argv[])    {        QCoreApplication app(argc, argv);        QTimer::singleShot(0, this, SLOT(run()));        app.exec();        return m_overallResult == 0;    }    private slots:    void run()    {        doRunTests();        QCoreApplication::instance()->quit();    }private:    void doRunTests()    {        // BEWARE: we assume either no command line parameters or evaluate first parameter ourselves        // usage:         //    help:                                        "TestSuite.exe -help"        //    run all test classes (with logging):         "TestSuite.exe"        //    print all test classes:                      "TestSuite.exe -classes"        //    run one test class with QtTest parameters:   "TestSuite.exe testClass [options] [testfunctions[:testdata]]...        if (QCoreApplication::arguments().size() > 1 && QCoreApplication::arguments()[1] == "-help")        {            qDebug() << "Usage:";            qDebug().noquote() << "run all test classes (with logging):\t\t" << qAppName();            qDebug().noquote() << "print all test classes:\t\t\t\t" << qAppName() << "-classes";            qDebug().noquote() << "run one test class with QtTest parameters:\t" << qAppName() << "testClass [options][testfunctions[:testdata]]...";            qDebug().noquote() << "get more help for running one test class:\t" << qAppName() << "testClass -help";            exit(0);        }        foreach(QObject * test, m_tests)        {            QStringList arguments;            QString testName = test->metaObject()->className();            if (QCoreApplication::arguments().size() > 1)            {                if (QCoreApplication::arguments()[1] == "-classes")                {                    // only print test classes                    qDebug().noquote() << testName;                    continue;                }                else                if (QCoreApplication::arguments()[1] != testName)                {                    continue;                }                else                {                    arguments = QCoreApplication::arguments();                    arguments.removeAt(1);                }            }            else            {                arguments.append(QCoreApplication::arguments()[0]);                // log to console                arguments.append("-o"); arguments.append("-,txt");                // log to file as TXT                arguments.append("-o"); arguments.append(mTestLogFolder % "/" % testName % ".log,txt");                // log to file as XML                arguments.append("-o"); arguments.append(mTestLogFolder % "/" % testName % ".xml,xunitxml");            }            m_overallResult |= QTest::qExec(test, arguments);        }    }    QList<QObject *> m_tests;    int m_overallResult;    const QString mTestLogFolder = "testLogs";};#endif // TESTRUNNER_H

使用方法如下：

int main(int argc, char* argv[]){    TestRunner testRunner;    //your QTest compatible class here    testRunner.addTest(new TestAdd);    testRunner.addTest(new TestQString);    bool pass = testRunner.runTests(argc, argv);    qDebug() << "Overall result: " << (pass ? "PASS" : "FAIL");    return pass ? 0 : 1;}
