[SOLVED] Linking Unit Test to MyProject

Nielske87

Hello,

I'm trying to make an Unit Test (using CppUnit) for MyProject.
I will describe the situation first.

I made 2 separated projects: MyProject and UnitTestProject.
The hierarchy looks like this:

Basefolder/
++ MyProject/
+++ trunk/
+++ myproject.pro
++++ controllers/
+++++ heating/
+++++ heatingcontroller.cpp
+++++ heatingcontroller.h
+++++ heatingonoffcontroller.cpp
+++++ heatingonoffcontroller.h

++ UnitTestProject/
+++ trunk/
+++ unittestproject.pro
++++ controllers/
+++++ heating/
+++++ ut_heatingonoff.cpp
+++++ ut_heatingonoff.h

unittestproject.pro looks like this:

@QT += testlib
QT -= gui

TARGET = tst_unittestproject
CONFIG += console
CONFIG -= app_bundle

TEMPLATE = app

INCLUDEPATH +=
../../MyProject/trunk/

DEPENDPATH +=
../../MyProject/trunk/

SOURCES +=
tst_unittestproject.cpp
heating/ut_heatingonoff.cpp

HEADERS +=
tst_unittestproject.h
heating/ut_heatingonoff.h

unix|win32: LIBS += -lcppunit@

In heatingonoffcontroller.h is a class named HeatingOnOffController
In ut_heatingonoff.h I made a class like this:
@
#include "controllers/heating/heatingcontroller.h"
#include "controllers/heating/heatingonoffcontroller.h"

class utHeatingOnOffController : public CppUnit::TestFixture
{

CPPUNIT_TEST_SUITE(utHeatingOnOffController);
CPPUNIT_TEST(testTestTest);
CPPUNIT_TEST_SUITE_END();

public:
void setUp(void);
void tearDown(void);

private:
HeatingOnOffController *TestObjectHeatingOnOffController;
};@

In ut_heatingonoffcontroller.cpp I made an implementation like this:

@
#include "controllers/heating/heatingcontroller.h"
#include "controllers/heating/heatingonoffcontroller.h"
#include "heating/ut_heatingonoffcontroller.h"

using namespace CppUnit;
using namespace std;

void utHeatingOnOffController::testTestTest(void)
{

}

void utHeatingOnOffController::setUp(void)
{
TestObjectHeatingOnOffController = new HeatingOnOffController(NULL,0,0);
}

void utHeatingOnOffController::tearDown(void)
{
delete TestObjectHeatingOnOffController;
}

CPPUNIT_TEST_SUITE_REGISTRATION(utHeatingOnOffController);@

The strange thing is that QtCreator recognizes HeatingOnOffController, but gives an error at this line:

@TestObjectHeatingOnOffController = new HeatingOnOffController(NULL,0,0);@

I get the following error:

In function 'void utHeatingOnOffController::setUp(void)':
undefined reference to 'HeatingOnOffController::HeatingOnOffController(QObject*,int,int)'
collect2: error: Id returned 1 exit status

I think it has something to do with the link between the 2 projects, but I don't know how to do that correct in the .pro files.
Does anybody know what I'm doing wrong? I'm struggling with it for days!

Hi,

You don't link your unit test to your MyProject library

Hi,

thanks for the reaction!
That's what I thought, but how do I do that?
Qt is kind of new to me.

Btw: Is it an option for me to create an library file of MyProject and include that in UnitTestProject.pro?

SGaist

Use the lib template and in your unit test add

@
LIBS +=
-Lpath_where_the_lib_file_from_MyProject_can_be_found
-lMyProject
@

and you should be good

YESYESYES!!!
It works!!!
Thanks SGaist!
