How to test QTableView cell editing in a unit test?

laucarlier

Hello,

I would like to verify in a unit test that my cell editing is working fine within a QTableView.

I have the following unit test which is not working and I'm wondering why (see below the crash message and the callstack)

void TestItemsManager::checkModifyPrice()
{
    ItemsModel model{}; // This is a QAbstractTableModel
    ItemsManager itemsManager{nullptr, &model}; // This is a QDialog

    ClickButtonAndCheckRowAdded(itemsManager, model, 0);

    auto tableView = itemsManager.findChild<QTableView*>("tableView");
    QCOMPARE_NE(tableView, nullptr);

    QModelIndex index = model.index(0, 1);
    QPoint pointToClick = tableView->visualRect(index).center();

    QTest::mouseDClick(tableView->viewport(), Qt::MouseButton::LeftButton, Qt::NoModifier, pointToClick);

    QTest::keyClicks(tableView->keyboardGrabber(), "3");
    QTest::keyClick(tableView->keyboardGrabber(), Qt::Key_Enter);

    std::array<QVariant, 10> rowToExpect =
    {
        QVariant{""},
        QVariant{"3.00 €"},
        QVariant{"15 %"},
        QVariant{"20 %"},
        QVariant{"0.45 €"},
        QVariant{"3.45 €"},
        QVariant{"0.69 €"},
        QVariant{"4.14 €"},
        QVariant{"0.87 €"},
        QVariant{"5.01 €"}
    };
    for(int idx = 0; idx < rowToExpect.size(); ++idx)
    {
        qDebug() << "idx = " << idx;
        QCOMPARE(model.data(model.index(0, idx)), rowToExpect[idx]);
    }
}

Here is the crash message

QFATAL : TestItemsManager::checkModifyPrice() ASSERT: "widget" in file C:\Qt\6.4.2\msvc2019_64\include\QtTest/qtestkeyboard.h, line 194

I do not want to directly call the setData function of my model because I want to make sure that the user can actually edit the cell by double clicking on the cell.

Can anybody tell me what I'm missing here?

Many thanks,

Kind regards,

Hi and welcome to devnet,

You should check that you actually got an editor.

Did you consider using the edit method ? It would be simpler than trying to click on the table view.
