函数文档编制

void QTest:: addColumn (const char * name , T * dummy = ...)

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.

范例：

void myTestFunction_data() {
    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 凭借 Q_DECLARE_METATYPE ().

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

见 数据驱动测试 了解更广泛范例。

另请参阅 QTest::newRow (), QFETCH ()，和 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 。见 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.

范例：

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

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

见 数据驱动测试 了解更广泛范例。

Retuns the units of measure for the specified metric .

该函数在 Qt 4.7 引入。

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

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.

该函数在 Qt 5.8 引入。

另请参阅 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 ()

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

const char *QTest:: currentTestFunction ()

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

范例：

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

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

Ignores messages created by qDebug (), qInfo () 或 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.

注意： 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.

范例：

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 )

这是重载函数。

Ignores messages created by qDebug (), qInfo () 或 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.

注意： 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.

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 创建测试 了解更多细节。

Optionally, the command line arguments argc and argv can be provided. For a list of recognized arguments, read Qt Test 命令行自变量 .

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.

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

这是重载函数。

Behaves identically to qExec ( QObject *, int, char**) but takes a QStringList of arguments 而不是 char** 列表。

该函数在 Qt 4.4 引入。

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 必须大于 0。

注意： 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.

范例：

QTest::qSleep(250);
					

另请参阅 QTest::qWait ().

void QTest:: qWait ( int ms )

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

范例：

    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.

另请参阅 QTest::qSleep () 和 QSignalSpy::wait ().

bool QTest:: qWaitFor ( Functor predicate , int timeout = 5000)

等待 timeout milliseconds or until the predicate returns true.

返回 true 若 predicate returned true at any point, otherwise returns false .

范例：

    MyObject obj;
    obj.startup();
    QTest::qWaitFor([&]() {
        return obj.isReady();
    }, 3000);
					

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

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

等待 timeout milliseconds or until the window is active.

返回 true if window is active within timeout milliseconds, otherwise returns false .

另请参阅 qWaitForWindowExposed () 和 QWindow::isActive ().

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

等待 timeout milliseconds or until the widget 's window is active.

返回 true if widget 's window is active within timeout milliseconds, otherwise returns false .

该函数在 Qt 5.0 引入。

另请参阅 qWaitForWindowExposed () 和 QWidget::isActiveWindow ().

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

等待 timeout milliseconds or until the window is exposed. Returns true if window is exposed within timeout milliseconds, otherwise returns false .

This is mainly useful for asynchronous systems like X11, where a window will be mapped to screen some time after being asked to show itself on the screen.

Note that a window that is mapped to screen may still not be considered exposed if the window client area is completely covered by other windows, or if the window is otherwise not visible. This function will then time out when waiting for such a window.

该函数在 Qt 5.0 引入。

另请参阅 qWaitForWindowActive () 和 QWindow::isExposed ().

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

等待 timeout milliseconds or until the widget 's window is exposed. Returns true if widget 's window is exposed within timeout milliseconds, otherwise returns false .

This is mainly useful for asynchronous systems like X11, where a window will be mapped to screen some time after being asked to show itself on the screen.

Note that a window that is mapped to screen may still not be considered exposed if the window client area is completely covered by other windows, or if the window is otherwise not visible. This function will then time out when waiting for such a window.

A specific configuration where this happens is when using QGLWidget as a viewport widget on macOS : The viewport widget gets the expose event, not the parent widget.

void QTest:: setBenchmarkResult ( qreal result , QTest::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.

该函数在 Qt 4.7 引入。

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.

length is the length of the string ba .

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.

注意： Starting with Qt 5.5, you should prefer to provide a toString() function in the type's namespace instead of specializing this template. If your code needs to continue to work with the QTestLib from Qt 5.4 or earlier, you need to continue to use specialization.

注意： The caller of toString() must delete the returned data using delete[] . Your implementation should return a string created with new[] or qstrdup (). The easiest way to do so is to create a QByteArray or QString and calling QTest::toString() on it (see second example below).

Example for specializing (Qt ≤ 5.4):

namespace QTest {
    template<>
    char *toString(const MyPoint &point)
    {
        QByteArray ba = "MyPoint(";
        ba += QByteArray::number(point.x()) + ", " + QByteArray::number(point.y());
        ba += ')';
        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 MyNamespace {
    char *toString(const MyPoint &point)
    {
        // bring QTest::toString overloads into scope:
        using QTest::toString;
        // delegate char* handling to QTest::toString(QByteArray):
        return toString("MyPoint(" +
                        QByteArray::number(point.x()) + ", " +
                        QByteArray::number(point.y()) + ')');
    }
}

宏文档编制

QBENCHMARK

This macro is used to measure the performance of code within a test. The code to be benchmarked is contained within a code block following this macro.

例如：

void TestBenchmark::simple()
{
    QString str1 = QLatin1String("This is a test string");
    QString str2 = QLatin1String("This is a test string");
    QCOMPARE(str1.localeAwareCompare(str2), 0);
    QBENCHMARK {
        str1.localeAwareCompare(str2);
    }
}

QBENCHMARK_ONCE

The QBENCHMARK_ONCE macro is for measuring performance of a code block by running it once.

This macro is used to measure the performance of code within a test. The code to be benchmarked is contained within a code block following this macro.

Unlike QBENCHMARK, the contents of the contained code block is only run once. The elapsed time will be reported as "0" if it's to short to be measured by the selected backend. (Use)

该函数在 Qt 4.6 引入。

另请参阅 创建基准测试 and 编写基准测试 .

QCOMPARE ( actual , expected )

The QCOMPARE macro compares an actual value to an expected value using the equals operator. If actual and expected are identical, execution continues. If not, a failure is recorded in the test log and the test won't be executed further.

In the case of comparing floats and doubles, qFuzzyCompare () is used for comparing. This means that comparing to 0 will likely fail. One solution to this is to compare to 1, and add 1 to the produced output.

QCOMPARE tries to output the contents of the values if the comparison fails, so it is visible from the test log why the comparison failed.

For your own classes, you can use QTest::toString () to format values for outputting into the test log.

注意： This macro can only be used in a test function that is invoked by the test framework.

范例：

QCOMPARE(QString("hello").toUpper(), QString("HELLO"));
					

另请参阅 QVERIFY (), QTRY_COMPARE ()，和 QTest::toString ().

QEXPECT_FAIL ( dataIndex , comment , mode )

The QEXPECT_FAIL() macro marks the next QCOMPARE () 或 QVERIFY () as an expected failure. Instead of adding a failure to the test log, an expected failure will be reported.

若 QVERIFY () 或 QCOMPARE () is marked as an expected failure, but passes instead, an unexpected pass (XPASS) is written to the test log.

参数 dataIndex describes for which entry in the test data the failure is expected. Pass an empty string ( "" ) if the failure is expected for all entries or if no test data exists.

comment will be appended to the test log for the expected failure.

mode 是 QTest::TestFailMode and sets whether the test should continue to execute or not.

注意： This macro can only be used in a test function that is invoked by the test framework.

Example 1:

QEXPECT_FAIL("", "Will fix in the next release", Continue);
QCOMPARE(i, 42);
QCOMPARE(j, 43);
					

In the example above, an expected fail will be written into the test output if the variable i is not 42. If the variable i is 42, an unexpected pass is written instead. The QEXPECT_FAIL() has no influence on the second QCOMPARE () statement in the example.

Example 2:

QEXPECT_FAIL("data27", "Oh my, this is soooo broken", Abort);
QCOMPARE(i, 42);
					

The above testfunction will not continue executing for the test data entry data27 .

另请参阅 QTest::TestFailMode , QVERIFY ()，和 QCOMPARE ().

QFAIL ( message )

This macro can be used to force a test failure. The test stops executing and the failure message is appended to the test log.

注意： This macro can only be used in a test function that is invoked by the test framework.

范例：

if (sizeof(int) != 4)
    QFAIL("This test has not been ported to this platform yet.");
					

QFETCH ( type , name )

The fetch macro creates a local variable named name with the type type on the stack. name has to match the element name from the test's data. If no such element exists, the test will assert.

Assuming a test has the following data:

void TestQString::toInt_data()
{
    QTest::addColumn<QString>("aString");
    QTest::addColumn<int>("expected");
    QTest::newRow("positive value") << "42" << 42;
    QTest::newRow("negative value") << "-42" << -42;
    QTest::newRow("zero") << "0" << 0;
}
					

The test data has two elements, a QString called aString and an integer called expected . To fetch these values in the actual test:

void TestQString::toInt()
{
     QFETCH(QString, aString);
     QFETCH(int, expected);
     QCOMPARE(aString.toInt(), expected);
}
					

aString and expected are variables on the stack that are initialized with the current test data.

注意： This macro can only be used in a test function that is invoked by the test framework. The test function must have a _data function.

QFINDTESTDATA ( filename )

返回 QString for the testdata file referred to by filename , or an empty QString if the testdata file could not be found.

This macro allows the test to load data from an external file without hardcoding an absolute filename into the test, or using relative paths which may be error prone.

The returned path will be the first path from the following list which resolves to an existing file or directory:

• filename relative to QCoreApplication::applicationDirPath () (only if a QCoreApplication or QApplication object has been created).
• filename relative to the test's standard install directory ( QLibraryInfo::TestsPath with the lowercased testcase name appended).
• filename relative to the directory containing the source file from which QFINDTESTDATA is invoked.

If the named file/directory does not exist at any of these locations, a warning is printed to the test log.

例如，在此代码中：

// Source: /home/user/sources/myxmlparser/tests/tst_myxmlparser/tst_myxmlparser.cpp
// Build:  /home/user/build/myxmlparser/tests/tst_myxmlparser
// Qt:     /usr/local/Qt-5.0.0
void tst_MyXmlParser::parse()
{
    MyXmlParser parser;
    QString input = QFINDTESTDATA("testxml/simple1.xml");
    QVERIFY(parser.parse(input));
}
					

The testdata file will be resolved as the first existing file from:

• /home/user/build/myxmlparser/tests/tst_myxmlparser/testxml/simple1.xml
• /usr/local/Qt-5.0.0/tests/tst_myxmlparser/testxml/simple1.xml
• /home/user/sources/myxmlparser/tests/tst_myxmlparser/testxml/simple1.xml

This allows the test to find its testdata regardless of whether the test has been installed, and regardless of whether the test's build tree is equal to the test's source tree.

注意： reliable detection of testdata from the source directory requires either that qmake is used, or the QT_TESTCASE_BUILDDIR macro is defined to point to the working directory from which the compiler is invoked, or only absolute paths to the source files are passed to the compiler. Otherwise, the absolute path of the source directory cannot be determined.

注意： For tests that use the QTEST_APPLESS_MAIN () macro to generate a main() function, QFINDTESTDATA will not attempt to find test data relative to QCoreApplication::applicationDirPath (). In practice, this means that tests using QTEST_APPLESS_MAIN() will fail to find their test data if run from a shadow build tree.

该函数在 Qt 5.0 引入。

QSKIP ( description )

If called from a test function, the QSKIP() macro stops execution of the test without adding a failure to the test log. You can use it to skip tests that wouldn't make sense in the current configuration. The text description is appended to the test log and should contain an explanation of why the test couldn't be executed.

If the test is data-driven, each call to QSKIP() will skip only the current row of test data, so an unconditional call to QSKIP will produce one skip message in the test log for each row of test data.

If called from an _data function, the QSKIP() macro will stop execution of the _data function and will prevent execution of the associated test function.

If called from initTestCase() or initTestCase_data(), the QSKIP() macro will skip all test and _data functions.

注意： This macro can only be used in a test function or _data function that is invoked by the test framework.

范例：

if (!QSqlDatabase::drivers().contains("SQLITE"))
    QSKIP("This test requires the SQLITE database driver");
					

QTEST ( actual , testElement )

QTEST() is a convenience macro for QCOMPARE () that compares the value actual with the element testElement from the test's data. If there is no such element, the test asserts.

Apart from that, QTEST() behaves exactly as QCOMPARE ().

Instead of writing:

QFETCH(QString, myString);
QCOMPARE(QString("hello").toUpper(), myString);
					

可以编写：

QTEST(QString("hello").toUpper(), "myString");

另请参阅 QTEST_MAIN ().

QTEST_MAIN ( TestClass )

Implements a main() function that instantiates an application object and the TestClass , and executes all tests in the order they were defined. Use this macro to build stand-alone executables.

若 QT_WIDGETS_LIB is defined, the application object will be a QApplication ，若 QT_GUI_LIB is defined, the application object will be a QGuiApplication , otherwise it will be a QCoreApplication . If qmake is used and the configuration includes QT += widgets ，那么 QT_WIDGETS_LIB will be defined automatically. Similarly, if qmake is used and the configuration includes QT += gui ，那么 QT_GUI_LIB will be defined automatically.

注意： On platforms that have keypad navigation enabled by default, this macro will forcefully disable it if QT_WIDGETS_LIB is defined. This is done to simplify the usage of key events when writing autotests. If you wish to write a test case that uses keypad navigation, you should enable it either in the initTestCase() or init() functions of your test case by calling QApplication::setNavigationMode ().
