using google test with Qt qml App

I'm new to TDD and Google Unit Test and having issues setting up some simple testing for class that #include <QObject>.

I have got the testing libraries installed for Qt Creator and have the Auto test plugin enabled
qtdeclarative5-dev-tools qtdeclarative5-test-plugin

I have a SUBDIR project that has two projects in it: one project is for the QML/C++ application and the other sub project is for Auto Unit Testing (Google Test & QtQuick Test)

Code:

---

TEMPLATE = subdirs
SUBDIRS += Application \
    AutoTests

---

I can create a simple class (multiply.cpp) in my qml/c++ app and able to test it in the my other sub-project GTest
Header file for multiply.cpp

Code:

---

#ifndef MULTIPLY_H
#define MULTIPLY_H
 
 
class Multiply
{
public:
    Multiply();
    int TwoNums(int x, int y);
};
 
#endif // MULTIPLY_H

---

Here is my Test Function for my multiply class example (I had to add existing files and select my multiply.cpp file and add it to this sub=projects sources)

Code:

---

#include <gtest/gtest.h>
#include <gmock/gmock-matchers.h>
#include "../../Application/Application/multiply.h"
 
using namespace testing;
 
TEST(Multiply_Test1, Multiply_Set1)
{
    Multiply multiplyObj;
    EXPECT_EQ(6, multiplyObj.TwoNums(2,3));
    ASSERT_THAT(0, Eq(0));
}

This is my project structure

I don't know if I need to mock the class to take away the dependencies of QObject sub class ? I not sure how to write an appropriate test for something that sub-classes another object

I'm having issue testing any class that use a sub class like QObject, Get errors saying fatal error: QObject: No such file or directory (this happens for each #include)

Code:

---

class ListView : public QObject
{
    Q_OBJECT

---

I'm also trying to get QtQuick Test to work with this project too but not having any luck understanding how to implement it fully
I set up an Auto Test SubDir
I have tried creating a test_Button.qml file with test cases in it
I added Macro for running QtQuick Test to a .cpp file so that the test "harness" can run the tests (test harness scans current directory for tst_ files) unless environment variable is set specifying path

Code:

---

QUICK_TEST_MAIN(example)

---

I'm not sure with the SUBDIR structure where my Quick Unit test should live

I'm I setting everything up correctly Google test? and QtQuick Test?

What is the best way to implement Auto Unit Testing in Qt using Google Tests ?

any advice or examples would be awesome

I been trying to get QtQuick Test implemented into and a simple project QML/C++.

I have created a subdir project with two sub projects one project holds app (QML/C++)

I used the Qt Creator Project wizard to create these sub-projects

I have the test libraries installed and have the plugin enabled for AutoTests Libraries: qtdeclarative5-dev-tools qtdeclarative5-test-plugin

I created a QML file in my auto test sub-project called tst_MyItem.qml
this is where I want to create my unit test using javaScript and TestCase object

In Order to test my QML file in my Application subproject:
I have tried importing the QML file into the tst_MyItem.qml file (says can't find it ...)
I have right clicked on my AutoTest sub project add Existing files and added MyItem.qml file from my Application sub-project into my AutoTest Sub-project
I have Tried adding MyItem as a component into tst_MyItem.qml
I have tried creating the tst_MyItem.qml (with javaScript Unit test funitons in it) inside my Application sub-project (mainPage) and tried calling macro from AutoTest Sub projects

Code:

---

TestCase {
    name: "Test_MyItem"
    //    MyItem{
    //        id: item
   //    }

---

I can create simple TestCase that are irrelevant to the QML I need to test and run it and have it pass or fail but not sure how to test the QML code I have written

Ex

Code:

---

import QtQuick 2.3
import QtTest 1.0
//import "../../../../HelloWorld/QML/MyItem.qml"
 
 
TestCase {
    name: "Test_MyItem"
 
//    MyItem{
//        id: item
//    }
 
    function test_testField_text() {
        var myString = "Hello World"
        compare(myString, "Hello World", "not equal")
    }
 
    function test_fail() {
        compare(2 + 2, 5, "2 + 2 = 5")
    }
}

---

C++ test harnsses main() call with MACRO

Code:

---

#include <QtTest>
#include <QtQuickTest>
#include <QtQuick/QtQuick>
#include <QCoreApplication>
 
QUICK_TEST_MAIN(Test_MyItem);

Here is MyItem.qml I want to write Unit tests for which is in my sub-project Application

Code:

---

import QtQml 2.2

    id: item

    height: 500
 
    //Sends text to c++ fcn
    signal submitTextField(string text)
 
    // this function is our QML slot
    function setTextField(text){
        console.log("setTextField: " + text)
        textField1.text = text
    }
 
    Button{
        id: quitButton

                console.log("Quit button clicked")

    }
 
    Button {

        y: 167
        text: qsTr("Uppercase me!")
        onClicked:
            // emit the submitTextField signal
            submitTextField(textField1.text)
    }
 
    Button{
        id:openWin_btn

        anchors.left: quitButton.right
