template <typename T> void QTest::addColumn(const char *name, T *dummy = 0)

Adds a column with type T to the current test data. name is the name of the column. dummy is a workaround for buggy compilers and can be ignored.

To populate the column with values, newRow() can be used. Use QFETCH() to fetch the data in the actual test.

Example:

     QTest::addColumn<int>("intval");
     QTest::addColumn<QString>("str");
     QTest::addColumn<double>("dbl");
     QTest::newRow("row1") << 1 << "hello" << 1.5;

To add custom types to the testdata, the type must be registered with QMetaType via Q_DECLARE_METATYPE().

Note: This macro can only be used in a test's data function that is invoked by the test framework.

See Data Driven Testing for a more extensive example.

See also QTest::newRow(), QFETCH(), and QMetaType.

QTestData &QTest::addRow(const char *format, ...)

Appends a new row to the current test data. The function's arguments are passed to qsnprintf() for formatting according to format. See the qvsnprintf() documentation for caveats and limitations.

The formatted string will appear as the name of this test data in the test output.

Returns a QTestData reference that can be used to stream in data.

Example:

     QTest::addColumn<int>("input");
     QTest::addColumn<QString>("output");
     QTest::addRow("%d", 0) << 0 << QString("0");
     QTest::addRow("%d", 1) << 1 << QString("1");

Note: This function can only be used in a test's data function that is invoked by the test framework.

See Data Driven Testing for a more extensive example.

This function was introduced in Qt 5.9.

See also addColumn() and QFETCH().

const char *QTest::benchmarkMetricName(QBenchmarkMetric metric)

Returns the enum value metric as a character string.

This function was introduced in Qt 4.7.

const char *QTest::benchmarkMetricUnit(QBenchmarkMetric metric)

Retuns the units of measure for the specified metric.

This function was introduced in Qt 4.7.

QTouchDevice *QTest::createTouchDevice(QTouchDevice::DeviceType devType = QTouchDevice::TouchScreen)

Creates a dummy touch device of type devType for simulation of touch events.

The touch device will be registered with the QPA window system interface, and deleted automatically when the QCoreApplication is deleted. So you should typically use createTouchDevice() to initialize a QTouchDevice member variable in your test case class, and use the same instance for all tests.

This function was introduced in Qt 5.8.

See also QTest::QTouchEventSequence and touchEvent().

const char *QTest::currentAppName()

Returns the name of the binary that is currently executed.

const char *QTest::currentDataTag()

Returns the name of the current test data. If the test doesn't have any assigned testdata, the function returns 0.

bool QTest::currentTestFailed()

Returns true if the current test function failed, otherwise false.

const char *QTest::currentTestFunction()

Returns the name of the test function that is currently executed.

Example:

 void MyTestClass::cleanup()
 {
     if (qstrcmp(QTest::currentTestFunction(), "myDatabaseTest") == 0) {
         // clean up all database connections
         closeAllDatabases();
     }
 }

void QTest::ignoreMessage(QtMsgType type, const char *message)

Ignores messages created by qDebug(), qInfo() or qWarning(). If the message with the corresponding type is outputted, it will be removed from the test log. If the test finished and the message was not outputted, a test failure is appended to the test log.

Note: Invoking this function will only ignore one message. If the message you want to ignore is outputted twice, you have to call ignoreMessage() twice, too.

Example:

 QDir dir;
 QTest::ignoreMessage(QtWarningMsg, "QDir::mkdir: Empty or null file name(s)");
 dir.mkdir("");

The example above tests that QDir::mkdir() outputs the right warning when invoked with an invalid file name.

void QTest::ignoreMessage(QtMsgType type, const QRegularExpression &messagePattern)

This is an overloaded function.

Ignores messages created by qDebug(), qInfo() or qWarning(). If the message matching messagePattern with the corresponding type is outputted, it will be removed from the test log. If the test finished and the message was not outputted, a test failure is appended to the test log.

Note: Invoking this function will only ignore one message. If the message you want to ignore is outputted twice, you have to call ignoreMessage() twice, too.

This function was introduced in Qt 5.3.

void QTest::keyClick(QWidget *widget, Qt::Key key, Qt::KeyboardModifiers modifier = Qt::NoModifier, int delay = -1)

Simulates clicking of key with an optional modifier on a widget. If delay is larger than 0, the test will wait for delay milliseconds before clicking the key.

Examples:

 QTest::keyClick(myWidget, Qt::Key_Escape);

 QTest::keyClick(myWidget, Qt::Key_Escape, Qt::ShiftModifier, 200);

The first example above simulates clicking the escape key on myWidget without any keyboard modifiers and without delay. The second example simulates clicking shift-escape on myWidget following a 200 ms delay of the test.

     QTest::newRow("just hello") << QString("hello");
     QTest::newRow("a null string") << QString();
 }

Note: This macro can only be used in a test's data function that is invoked by the test framework.

See Data Driven Testing for a more extensive example.

See also addColumn() and QFETCH().

int QTest::qExec(QObject *testObject, int argc = 0, char **argv = nullptr)

Executes tests declared in testObject. In addition, the private slots initTestCase(), cleanupTestCase(), init() and cleanup() are executed if they exist. See Creating a Test for more details.

Optionally, the command line arguments argc and argv can be provided. For a list of recognized arguments, read Qt Test Command Line Arguments.

The following example will run all tests in MyTestObject:

 MyTestObject test1;
 QTest::qExec(&test1);

This function returns 0 if no tests failed, or a value other than 0 if one or more tests failed or in case of unhandled exceptions. (Skipped tests do not influence the return value.)

For stand-alone test applications, the convenience macro QTEST_MAIN() can be used to declare a main() function that parses the command line arguments and executes the tests, avoiding the need to call this function explicitly.

The return value from this function is also the exit code of the test application when the QTEST_MAIN() macro is used.

For stand-alone test applications, this function should not be called more than once, as command-line options for logging test output to files and executing individual test functions will not behave correctly.

Note: This function is not reentrant, only one test can run at a time. A test that was executed with qExec() can't run another test via qExec() and threads are not allowed to call qExec() simultaneously.

If you have programatically created the arguments, as opposed to getting them from the arguments in main(), it is likely of interest to use QTest::qExec(QObject *, const QStringList &) since it is Unicode safe.

See also QTEST_MAIN().

int QTest::qExec(QObject *testObject, const QStringList &arguments)

This is an overloaded function.

Behaves identically to qExec(QObject *, int, char**) but takes a QStringList of arguments instead of a char** list.

This function was introduced in Qt 4.4.

QSharedPointer<QTemporaryDir> QTest::qExtractTestData(const QString &dirName)

Extracts a directory from resources to disk. The content is extracted recursively to a temporary folder. The extracted content is removed automatically once the last reference to the return value goes out of scope.

dirName is the name of the directory to extract from resources.

Returns the temporary directory where the data was extracted or null in case of errors.

void QTest::qSleep(int ms)

Sleeps for ms milliseconds, blocking execution of the test. qSleep() will not do any event processing and leave your test unresponsive. Network communication might time out while sleeping. Use QTest::qWait() to do non-blocking sleeping.

ms must be greater than 0.

Note: The qSleep() function calls either nanosleep() on unix or Sleep() on windows, so the accuracy of time spent in qSleep() depends on the operating system.

Example:

 QTest::qSleep(250);

See also QTest::qWait().

void QTest::qWait(int ms)

Waits for ms milliseconds. While waiting, events will be processed and your test will stay responsive to user interface events or network communication.

Example:

     int i = 0;
     while (myNetworkServerNotResponding() && i++ < 50)
         QTest::qWait(250);

The code above will wait until the network server is responding for a maximum of about 12.5 seconds.

See also QTest::qSleep() and QSignalSpy::wait().

template <typename Functor> bool QTest::qWaitFor(Functor predicate, int timeout = 5000)

Waits for timeout milliseconds or until the predicate returns true.

Returns true if the predicate returned true at any point, otherwise returns false.

Example:

The code above will wait for the object to become ready, for a maximum of three seconds.

This function was introduced in Qt 5.10.

bool QTest::qWaitForWindowActive(QWindow *window, int timeout = 5000)

Returns true, if window is active within timeout milliseconds. Otherwise returns false.

The method is useful in tests that call QWindow::show() and rely on the window actually being active (i.e. being visible and having focus) before proceeding.

This function was introduced in Qt 5.0.

See also qWaitForWindowExposed() and QWindow::isActive().

bool QTest::qWaitForWindowActive(QWidget *widget, int timeout = 5000)

Returns true if widget is active within timeout milliseconds. Otherwise returns false.

The method is useful in tests that call QWidget::show() and rely on the widget actually being active (i.e. being visible and having focus) before proceeding.

See also qWaitForWindowExposed() and QWidget::isActiveWindow().

bool QTest::qWaitForWindowExposed(QWindow *window, int timeout = 5000)

Returns true, if window is exposed within timeout milliseconds. Otherwise returns false.

The method is useful in tests that call QWindow::show() and rely on the window actually being being visible before proceeding.

This function was introduced in Qt 5.0.

See also qWaitForWindowActive() and QWindow::isExposed().

bool QTest::qWaitForWindowExposed(QWidget *widget, int timeout = 5000)

Returns true if widget is exposed within timeout milliseconds. Otherwise returns false.

The method is useful in tests that call QWidget::show() and rely on the widget actually being being visible before proceeding.

This function was introduced in Qt 5.0.

See also qWaitForWindowActive(), QWidget::isVisible(), and QWindow::isExposed().

void QTest::setBenchmarkResult(qreal result, QBenchmarkMetric metric)

Sets the benchmark result for this test function to result.

Use this function if you want to report benchmark results without using the QBENCHMARK macro. Use metric to specify how Qt Test should interpret the results.

The context for the result will be the test function name and any data tag from the _data function. This function can only be called once in each test function, subsequent calls will replace the earlier reported results.

Note that the -iterations command line argument has no effect on test functions without the QBENCHMARK macro.

This function was introduced in Qt 4.7.

char *QTest::toHexRepresentation(const char *ba, int length)

Returns a pointer to a string that is the string ba represented as a space-separated sequence of hex characters. If the input is considered too long, it is truncated. A trucation is indicated in the returned string as an ellipsis at the end. The caller has ownership of the returned pointer and must ensure it is later passed to operator delete[].

length is the length of the string ba.

template <typename T> char *QTest::toString(const T &value)

Returns a textual representation of value. This function is used by QCOMPARE() to output verbose information in case of a test failure.

You can add specializations or overloads of this function to your test to enable verbose output.

Example for specializing (Qt ≤ 5.4):

 namespace QTest {
     template<>
     char *toString(const MyPoint &point)
     {
         const QByteArray ba("MyPoint("
                             + QByteArray::number(point.x()) + ", "
                             + QByteArray::number(point.y()) + ')');
         return qstrdup(ba.data());
     }
 }

The example above defines a toString() specialization for a class called MyPoint. Whenever a comparison of two instances of MyPoint fails, QCOMPARE() will call this function to output the contents of MyPoint to the test log.

Same example, but with overloading (Qt ≥ 5.5):

 namespace {
     char *toString(const MyPoint &point)
     {
         return QTest::toString("MyPoint(" +
                                QByteArray::number(point.x()) + ", " +
                                QByteArray::number(point.y()) + ')');
     }
 }

QTouchEventSequence QTest::touchEvent(QWindow *window, QTouchDevice *device, bool autoCommit)

Creates and returns a QTouchEventSequence for the device to simulate events for window.

When adding touch events to the sequence, window will also be used to translate the position provided to screen coordinates, unless another window is provided in the respective calls to press(), move() etc.

The touch events are committed to the event system when the destructor of the QTouchEventSequence is called (ie when the object returned runs out of scope), unless autoCommit is set to false. When autoCommit is false, commit() has to be called manually.

createTouchDevice() can be called to create a test touch device for use with this function.

This function was introduced in Qt 5.0.
