Chapter 3: Simulating GUI Events▲
<Unknown command>contentspage{Qt Test Tutorial}{Contents}
Qt Test features some mechanisms to test graphical user interfaces. Instead of simulating native window system events, Qt Test sends internal Qt events. That means there are no side-effects on the machine the tests are running on.
In this chapter we will see how to write a simple GUI test.
Writing a GUI Test▲
This time, let's assume you want to test the behavior of our https:// class. As before, you will need a class that contains your test function:
#include <QtWidgets>
#include <QtTest/QtTest>
class TestGui: public QObject
{
Q_OBJECT
private slots:
void testGui();
};The only difference is that you need to include the Qt GUI class definitions in addition to the https:// namespace.
void TestGui::testGui()
{
QLineEdit lineEdit;
QTest::keyClicks(&lineEdit, "hello world");
QCOMPARE(lineEdit.text(), QString("hello world"));
}In the implementation of the test function we first create a https://. Then we simulate writing "hello world" in the line edit using the https://() function.
The widget must also be shown in order to correctly test keyboard shortcuts.
https://() simulates clicking a sequence of keys on a widget. Optionally, a keyboard modifier can be specified as well as a delay (in milliseconds) of the test after each key click. In a similar way, you can use the https://(), https://(), https://(), https://(), https://(), https://(), https://() and https://() functions to simulate the associated GUI events.
Finally, we use the https://() macro to check if the line edit's text is as expected.
As before, to make our test case a stand-alone executable, the following two lines are needed:
QTEST_MAIN(TestGui)
#include "testgui.moc"The https://() macro expands to a simple main() method that runs all the test functions, and since both the declaration and the implementation of our test class are in a .cpp file, we also need to include the generated moc file to make Qt's introspection work.
