QtTest Test Multiple Classes

sandro4912

IS it possible to have two test classes in one project?

I tryed to add QTEST_MAIN in the two cpp files of the test classes but it does not work.

Do i have to make one sub project per class i want to test?

Whats the normal approach with QtTest?

Hi,

I am not sure I exactly get your point but I think what you are after is described in this article.

Hope it helps

I followed all the steps in the article but when try to tun my tests i get this:

QFATAL : TestRoom::room() QWidget: Must construct a QApplication before a QWidget
FAIL!  : TestRoom::room() Received a fatal error.
   Loc: [Unknown file(0)]
Totals: 1 passed, 1 failed, 0 skipped, 0 blacklisted, 0ms
********* Finished testing of TestRoom *********
19:37:29: The program has unexpectedly finished.

The class i want to test is derrived from QWidget. What can I do to exceute the tests?

Here my code:

QT += widgets
QT += testlib
QT += gui
CONFIG += c++17 console

TEMPLATE = app

include (../hunt_the_wumpus-src.pri)

APP_PATH = ../src
INCLUDEPATH += $$APP_PATH
DEPENDPATH += $$APP_PATH

HEADERS += \
    testroom.h \
    testsuite.h

SOURCES += \
    main.cpp \
    testroom.cpp \
    testsuite.cpp

#ifndef TESTSUITE_H
#define TESTSUITE_H

#include <QObject>
#include <vector>

class TestSuite: public QObject
{
public:
     TestSuite();

     static std::vector<QObject*> & suite();
};
#endif // TESTSUITE_H

#include "testsuite.h"

TestSuite::TestSuite()
{
    suite().push_back(this);
}


std::vector<QObject*> & TestSuite::suite()
{
    static std::vector<QObject*> objects;
    return objects;
}

#ifndef TESTROOM_H
#define TESTROOM_H

#include "testsuite.h"
#include <QtTest/QtTest>

class TestRoom : public TestSuite
{
    Q_OBJECT
public:
    using TestSuite::TestSuite;

private slots:

    void room_data();
    void room();

    void setAndHasPit_data();
    void setAndHasPit();

    void setAndHasBat_data();
    void setAndHasBat();

    void setAndHasPlayer_data();
    void setAndHasPlayer();

    void setAndPlayerWasHere_data();
    void setAndPlayerWasHere();
};

#endif // TESTROOM_H

#include "testroom.h"
#include "room.h"

/// all the tests

static TestRoom TEST_ROOM;

#include "testsuite.h"
#include <QtTest/QtTest>

int main(int argc, char *argv[])
{
    // setup lambda
    int status = 0;
    auto runTest = [&status, argc, argv](QObject* obj) {
        status |= QTest::qExec(obj, argc, argv);
    };

    // run suite
    auto &suite = TestSuite::suite();
    for (auto it = suite.begin(); it != suite.end(); ++it) {
        runTest(*it);
    }
}

ok this could be solved easy with adding QApplication to main:

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    // setup lambda
    int status = 0;
    auto runTest = [&status, &argc, argv](QObject* obj) {
        status |= QTest::qExec(obj, argc, argv);
    };

    // run suite
    auto &suite = TestSuite::suite();
    for (auto it = suite.begin(); it != suite.end(); ++it) {
        runTest(*it);
    }
}

Only sad part i can't see the tests under Tools->Tests anymore. So only Application Output with this method I guess.

This also breaks test output to file (xml/xunit/csv). It's just cleaner and better to create a separate project for each test with an individual main if you want to use the Qt Test framework
