QSignalSpy error: No such signal when connecting a signal to a QSignalSpy

Question

I am trying to test a Qt application that uses QML. Specifically, I want to test the connection between a signal emitted by a QML object and a slot in a C++ class.

Here's the relevant code I'm working with:

QQuickView view;
view.setSource(QUrl("qrc:/QML/monitoring/MonitoringMenu.qml")); // Path to the QML file
QQuickView view2;
view2.setSource(QUrl("qrc:/QML/monitoring/MonitoringAction.qml")); // Path to the QML file
QObject *object = view.rootObject();
QObject *object2 = view2.rootObject();

// Get the InspirationPausePanel object created in the QML file
QQuickItem *InspirationPausePanel = static_cast<QQuickItem*>(object->children().at(2));
Q_ASSERT(InspirationPausePanel != nullptr);

// Before clicking, check that the visible property is set to false
QCOMPARE(InspirationPausePanel->property("visible").toBool(), false);

// Get the InspirationPauseItem object created in the QML file
QQuickItem *InspirationPauseItem = static_cast<QQuickItem*>(object2->children().at(0));
Q_ASSERT(InspirationPauseItem != nullptr);

QObject::connect(object2, SIGNAL(actionClicked()), object2, SLOT(onActionClicked()));

// Connect the "actionClicked" signal of InspirationPauseItem to a QSignalSpy
QSignalSpy spy(object2, SIGNAL(actionClicked));
QVERIFY2(spy.isValid(), "signal not connected");

// Simulate a mouse click on the InspirationPauseItem object
QMetaObject::invokeMethod(InspirationPauseItem, "click");

// Check that the visible property of InspirationPausePanel is set to true
QCOMPARE(InspirationPausePanel->property("visible").toBool(), true);`

However, when I run the test, I get the following error:

QWARN  : MainwindowTest::clickButtonTest() QSignalSpy: No such signal: 'actionClicked'
FAIL!  : MainwindowTest::clickButtonTest() 'spy.isValid()' returned FALSE. (signal not connected)
..`/FHF_App/mainwindowtest.cpp(76) : failure location

It seems like the actionClicked signal is not being recognized. Please, can anyone help me figure out what I'm doing wrong?

For those who also stumbled upon this question, I want to say that Everything is much simpler. You just need the signal from C++ to have QVariant arguments. For example:

QSignalSpy spy(object2, SIGNAL(actionClicked(QVariant)));

My signal is declared like this:

signal actionClicked(var actionMode)
