`[since 5.13]` bool QQuickTest:: qIsPolishScheduled (const QQuickItem * item )

返回 true if updatePolish() has not been called on item since the last call to polish() ，否则返回 false .

When assigning values to properties in QML, any layouting the item must do as a result of the assignment might not take effect immediately, but can instead be postponed until the item is polished. For these cases, you can use this function to ensure that the item has been polished before the execution of the test continues. For example:

QVERIFY(QQuickTest::qIsPolishScheduled(item));
QVERIFY(QQuickTest::qWaitForItemPolished(item));

Without the call to qIsPolishScheduled() above, the call to qWaitForItemPolished() might see that no polish was scheduled and therefore pass instantly, assuming that the item had already been polished. This function makes it obvious why an item wasn't polished and allows tests to fail early under such circumstances.

The QML equivalent of this function is isPolishScheduled() .

该函数在 Qt 5.13 引入。

另请参阅 QQuickItem::polish () 和 QQuickItem::updatePolish ().

`[since 5.13]` bool QQuickTest:: qWaitForItemPolished (const QQuickItem * item , int timeout = 5000)

等待 timeout milliseconds or until updatePolish() has been called on item .

返回 true if updatePolish() was called on item 在 timeout milliseconds, otherwise returns false .

The QML equivalent of this function is waitForItemPolished() .

该函数在 Qt 5.13 引入。

宏文档编制

QUICK_TEST_MAIN ( name )

Sets up the entry point for a Qt Quick Test application. The name argument uniquely identifies this set of tests.

#include <QtQuickTest>
QUICK_TEST_MAIN(example)

注意： The macro assumes that your test sources are in the current directory, unless the QUICK_TEST_SOURCE_DIR environment variable is set.

QUICK_TEST_MAIN_WITH_SETUP ( name , QuickTestSetupClass )

Sets up the entry point for a Qt Quick Test application. The name argument uniquely identifies this set of tests.

This macro is identical to QUICK_TEST_MAIN (), except that it takes an additional argument QuickTestSetupClass , a pointer to a QObject -derived class. With this class it is possible to define additional setup code to execute before running the QML test.

注意： The macro assumes that your test sources are in the current directory, unless the QUICK_TEST_SOURCE_DIR environment variable is set.

The following snippet demonstrates the use of this macro:

// src_qmltest_qquicktest.cpp
#include <QtQuickTest>
#include <QQmlEngine>
#include <QQmlContext>
class Setup : public QObject
{
    Q_OBJECT
public:
    Setup() {}
public slots:
    void qmlEngineAvailable(QQmlEngine *engine)
    {
        engine->rootContext()->setContextProperty("myContextProperty", QVariant(true));
    }
};
QUICK_TEST_MAIN_WITH_SETUP(mytest, Setup)
#include "src_qmltest_qquicktest.moc"
