[英]Qt UI testing: How to simulate a click on a QMenuBar item using QTest?
[英]How to grab pointer to popup dialog in Qt which blocks the UI thread in QTest
我正在使用QTest编写集成测试,在该测试中,一旦单击窗口小部件的视口,就会出现多行弹出QInputDialog,它会阻止代码的进一步执行,并且需要手动取消对话框。 这是代码:
void PartTest::testTypewriterAnnotTool()
{
Okular::Part part(nullptr, nullptr, QVariantList()); // It is the main widget of PDF reader comprising of viewport where PDF page is shown
part.openUrl(QUrl::fromLocalFile(QStringLiteral(KDESRCDIR "data/file1.pdf"))); // open file1.pdf
part.widget()->show();
QVERIFY(QTest::qWaitForWindowExposed(part.widget()));
// Width and height of pageView widget, the child of Part widget which shows the PDF page
const int width = part.m_pageView->horizontalScrollBar()->maximum() +
part.m_pageView->viewport()->width();
const int height = part.m_pageView->verticalScrollBar()->maximum() +
part.m_pageView->viewport()->height();
part.m_document->setViewportPage(0); // sets viewport page 0, i.e. page number 1
QMetaObject::invokeMethod(part.m_pageView, "slotToggleAnnotator", Q_ARG( bool, true )); // toggles and shows the annotation toolbar with all tools avaialable
QList<QToolButton *> toolbuttonList = part.m_pageView->findChildren<QToolButton *>(); // find a list of annotation toolbutton
// Check if the tooltip of 10th button is "Typewriter"
QToolButton* typewriterButton = toolbuttonList.at(9);
QCOMPARE( typewriterButton->toolTip(), QStringLiteral("Typewriter") );
typewriterButton->click(); // clicking and selecting typewriter annotation tool
QTest::mouseMove(part.m_pageView->viewport(), QPoint(width * 0.5, height * 0.2)); // leading mouse pointer to a specific point in the viewport
QTest::mouseClick(part.m_pageView->viewport(), Qt::LeftButton, Qt::NoModifier, QPoint(width * 0.5, height * 0.2)); // mouse left button click on the viewport and a popup dialog with 'add a new note' appears
}
我必须编写一个测试用例,在其中必须抓住该弹出对话框并以编程方式将其关闭。 我正在尝试通过使用QTimer来实现这一点,在这里,我将在单击视口1秒钟后执行一个函数来捕获对话框,然后尝试像这样关闭它:
class PartTest
{
...
private:
Okular::part *m_part;
}
void PartTest::testTypewriterAnnotTool()
{
...
m_part = ∂
QTimer* mTimer = new QTimer(this);
mTimer->setSingleShot(true);
connect(mTimer, SIGNAL(timeout()), SLOT(testDialogClosed()));
mTimer->start(1000);
QTest::mouseClick(part.m_pageView->viewport(), Qt::LeftButton, Qt::NoModifier, QPoint(width * 0.5, height * 0.2));
}
void PartTest::testDialogClosed()
{
bool m_clicked = false;
QDialog *dialog = m_part->widget()->findChild<QDialog*>();
if (dialog)
{
QDialogButtonBox *buttonBox = dialog->findChild<QDialogButtonBox*>();
buttonBox->button(QDialogButtonBox::Cancel)->click();
m_clicked = true;
}
QVERIFY(m_clicked);
}
在这里, QVERIFY(m_clicked)
测试用例始终“失败”,这意味着弹出的QInputDialog is not the child of Okular::Part
并且我没有办法抓住指向该对话框窗口的指针并关闭它。 有什么帮助吗?
您可以枚举顶级小部件并以这种方式找到对话框:
template <class P> QList<P> topLevelWidgets() {
QList<P> widgets
for (auto *w : QApplication::topLevelWidgets())
if (auto *t = qobject_cast<P>(w))
widgets << t;
return widgets;
}
template <class P> P topLevelWidget() {
auto w = topLevelWidgets<P>();
return (w.size() == 1) ? w.first() : nullptr;
}
void PartTest::testDialogClosed()
{
bool m_clicked = false;
if (auto *dialog = topLevelWidget<QDialog*>())
if (auto *buttonBox = dialog->findChild<QDialogButtonBox*>()) {
buttonBox->button(QDialogButtonBox::Cancel)->click();
m_clicked = true;
}
QVERIFY(m_clicked);
}
