Qt Unit test in a project

Did I need to add something extra for the linking of these two subdirectories in my CMakeLists.txt files

You need to add source files (*.cpp) you want to test.
As you can see from the errors you are missing the source file containing Calculator definition.

@jsulm are you trying to say that I also need to add the calculator class into tests project? I already have the Calculator class implemented into src project.

No, you need to add a reference to that file to your test project, something like:

add_executable(${PROJECT_NAME}
    PATH_TO/calculator.cpp
    tst_unittest.cpp
    ...
)

If the code you want to test compiles to a lib you could instead add a dependency to this lib.

@jsulm Its working now. Thanks for response

Hi, I also want to include Qt Quick Test in same project. I added required directives into project. but I have one problem that I already have the main definition and it will not take another main definition. Please tell me how cam I add

QUICK_TEST_MAIN(example)

this code into main function? @jsulm

Are you trying to test a cpp file containing main()?
Why?
There should not be anything to test. If there is something you want to test, then move that functionality in functions/methods outside of that source file.

@jsulm No I want to test qml file which is present in my src project. And I want to integrate both cpp testing and qml testing into in single project which is tests. thats why I want to integrate that macro in main function. How can I do that, any idea?

Make sure you have only one main() in your test project.

[HemantSuryawanshi]

@jsulm

#include <QtTest>
#include <QDebug>
#include <tst_unittest.cpp>
#include <tst_userdata.cpp>

#include <QtQuickTest/quicktest.h>
QUICK_TEST_MAIN(example)

int main(int argc, char** argv)
{
   int failedTests = 0;
   failedTests += QTest::qExec(new UnitTest, argc, argv);
   failedTests += QTest::qExec(new TestUserData, argc, argv);

   if(failedTests > 0){
       qDebug() << "total number of failed tests: " << failedTests;
   }else{
       qDebug() << "all tests passed :)";
   }
   return failedTests;
}

This is my main file. My project contains multiple unit tests including Qt test and Qt Quick test. In this I am getting error that redefinition of main function due to the QUICK_TEST_MAIN Macro.

Of course, you have two main() functions now.
I suggest you split your C++ and Qt Quick tests.

@jsulm how can I link the qml file to the Qt Quick test project. I tried with same way as I link cpp file earlier, but its not working.
