QML TestCase not working. Why?

bogong

Hello!
I am trying to use QML TestCase in the way of:

import QtQuick 2.15
import QtQuick.Window 2.15
import QtTest 1.15

Window {

	id: oMainWindow;
	visible: true;
	width: 640;
	height: 480;
	title: qsTr("Hello World");

	TestCase {

		name: "QMLTestExample";

		function test_Example_01() {

			 compare(2 + 2, 4, "2 + 2 = 4");
		}

		function test_Example_02() {

			compare(2 + 2, 5, "2 + 2 = 5");
		}
	}
}

It's just default application where added TestCase QML component. It's not working. There are error:

QQmlApplicationEngine failed to load component
qrc:/main.qml:32:2: Type TestCase unavailable
file:///Users/alexandr/Tools/qt/5.15.0/clang_64/qml/QtTest/TestCase.qml:44:1: module "Qt.test.qtestroot" is not installed

Why is that? What am I missing?

Solution found. Issue closed.
Forgotten about:

in *.pro file

CONFIG += qmltestcase

in main.cpp

#include <QtQuickTest>
QUICK_TEST_MAIN(example)

rename main.qml file onto tst_gui.qml (any other tests should be OK with name like this "tst_*.qml") and use this

// System includes
import QtQuick 2.15
import QtTest 1.15

// Application includes


// Application window component
TestCase {

	name: "MathTests";

	function test_math() {
		compare(2 + 2, 4, "2 + 2 = 4");
	}

	function test_fail() {
		compare(2 + 2, 5, "2 + 2 = 5");
	}
}

All based on https://doc.qt.io/qt-5/qtquicktest-index.html#running-tests
Example is here https://github.com/ArboreusSystems/arboreus_examples/tree/master/qt/QTest/UnitTest_v4

Happy testing to all.
