Question

Basically I am following the basic example here. My .pro file contains QT += core network qtestlib. [Solved] testlib instead of typo qtestlib

When I include QVERIFY, It get the following linker error:

testwaypointlist.obj:-1: error: LNK2019: unresolved external symbol "bool __cdecl
QTest::qVerify(bool,char const *,char const *,char const *,int)"
(?qVerify@QTest@@YA_N_NPBD11H@Z) referenced in function "private: void __thiscall
TestWaypointList::fillWaypoints(void)" (?fillWaypoints@TestWaypointList@@AAEXXZ)

What files do I miss to link? Without QVERIFY the linker error disappears.

Header file:

#include <QObject>
#include <QtTest/QtTest>
#include "waypointlist.h"

//
// Testing the waypoint list
//
class TestWaypointList : public QObject
{
    Q_OBJECT

private:
    WaypointList _waypointList;
public:
    explicit TestWaypointList(QObject *parent = 0);
private slots:
    void fillWaypoints();
};

cpp:

//
// Fill the waypoint list
//
void TestWaypointList::fillWaypoints()
{
    _waypointList = WaypointList();
    .....

    for (int i=0; i < TESTWPLISTCOUNT; i++) {
        .....
        TestWaypointList::_waypointList.updateOrAppend(id, timeframe);
    }
    QVERIFY(TestWaypointList::_waypointList.count() == 1); // causing the linker error
}

In your .pro file, you need to change QT += qtestlib to QT += testlib (note the absence of a “q”).

Of note, you used to be able to do this: CONFIG += qtestlib, but according to the comment on this page, this is no longer the recommended way of linking to the test library.
