Testing a button click event in QtTest

How to test a button click event of the button created like :
Button *plusButton = createButton(tr("+"), SLOT(additiveOperatorClicked()));
in widget based app.

As far as I know createButton is not a standard method of Qt. In any case, what do you mean by Testing? if it's unit testing you can use https://doc.qt.io/qt-5/qttestlib-tutorial3-example.html

QTest::mouseClick(plusButton,Qt::LeftButton);

This is for unit Testing :
Calculator::Calculator(QWidget *parent)
: QWidget(parent)
{
Button *plusButton = createButton(tr("+"), SLOT(additiveOperatorClicked()));
}
This is the code snippet and I tried
QTest::mouseClick(calculator->plusButton,Qt::LeftButton);
But it shows nomember named plusButton in calculator but in the calculator pointer suggestions additiveOperatorClicked() is shown.

@shravan_121 said in Testing a button click event in QtTest:

But it shows nomember named plusButton in calculator

Because your plusButton is a LOCAL variable inside constructor. Add it as member variable to Calculator class.

@shravan_121 This is really basic C++, I suggest you read a book.

class Calculator
{
public:
    Button *plusButton;
};
...
Calculator::Calculator(QWidget *parent)
: QWidget(parent)
{
    plusButton = createButton(tr("+"), SLOT(additiveOperatorClicked()));
}
