<h2>Function Documentation</h2>
<h3 class="fn"><a name="addColumn"></a>void QTest::addColumn ( const char * <i>name</i>, T * <i>dummy</i> = 0 )</h3>
<p>Adds a column with type <tt>T</tt> to the current test data. <i>name</i> is the name of the column. <i>dummy</i> is a workaround for buggy compilers and can be ignored.</p>
<p>To populate the column with values, <a href="qtest.html#newRow">newRow</a>() can be used. Use <a href="qtest.html#QFETCH">QFETCH</a>() to fetch the data in the actual test.</p>
<p>Example:</p>
<pre> void myTestFunction_data() {
QTest::addColumn<int>("intval");
QTest::addColumn<QString>("str");
QTest::addColumn<double>("dbl");
QTest::newRow("row1") << 1 << "hello" << 1.5;
}</pre>
<p>To add custom types to the testdata, the type must be registered with <a href="qmetatype.html">QMetaType</a> via <a href="qmetatype.html#Q_DECLARE_METATYPE">Q_DECLARE_METATYPE</a>().</p>
<p><b>Note:</b> This macro can only be used in a test's data function that is invoked by the test framework.</p>
<p>See <a href="qtestlib-tutorial2.html">Data Driven Testing</a> for a more extensive example.</p>
<p>See also <a href="qtest.html#newRow">QTest::newRow</a>(), <a href="qtest.html#QFETCH">QFETCH</a>(), and <a href="qmetatype.html">QMetaType</a>.</p>
<h3 class="fn"><a name="currentDataTag"></a>const char * QTest::currentDataTag ()</h3>
<p>Returns the name of the current test data. If the test doesn't have any assigned testdata, the function returns 0.</p>
<h3 class="fn"><a name="currentTestFailed"></a>bool QTest::currentTestFailed ()</h3>
<p>Returns true if the current test function failed, otherwise false.</p>
<h3 class="fn"><a name="currentTestFunction"></a>const char * QTest::currentTestFunction ()</h3>
<p>Returns the name of the test function that is currently executed.</p>
<p>Example:</p>
<pre> void MyTestClass::cleanup()
{
if (qstrcmp(currentTestFunction(), "myDatabaseTest") == 0) {
<span class="comment">// clean up all database connections</span>
closeAllDatabases();
}
}</pre>
<h3 class="fn"><a name="ignoreMessage"></a>void QTest::ignoreMessage ( <a href="qtglobal.html#QtMsgType-enum">QtMsgType</a> <i>type</i>, const char * <i>message</i> )</h3>
<p>Ignores messages created by <a href="qtglobal.html#qDebug">qDebug</a>() or <a href="qtglobal.html#qWarning">qWarning</a>(). If the <i>message</i> with the corresponding <i>type</i> is outputted, it will be removed from the test log. If the test finished and the <i>message</i> was not outputted, a test failure is appended to the test log.</p>
<p><b>Note:</b> 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.</p>
<p>Example:</p>
<pre> QDir dir;
QTest::ignoreMessage(QtWarningMsg, "QDir::mkdir: Empty or null file name(s)");
dir.mkdir("");</pre>
<p>The example above tests that <a href="qdir.html#mkdir">QDir::mkdir</a>() outputs the right warning when invoked with an invalid file name.</p>
<h3 class="fn"><a name="keyClick"></a>void QTest::keyClick ( <a href="qwidget.html">QWidget</a> * <i>widget</i>, <a href="qt.html#Key-enum">Qt::Key</a> <i>key</i>, <a href="qt.html#KeyboardModifier-enum">Qt::KeyboardModifiers</a> <i>modifier</i> = Qt::NoModifier, int <i>delay</i> = -1 ) <tt> [static]</tt></h3>
<p>Simulates clicking of <i>key</i> with an optional <i>modifier</i> on a <i>widget</i>. If <i>delay</i> is larger than 0, the test will wait for <i>delay</i> milliseconds.</p>
<p>Examples:</p>
<pre> QTest::keyClick(myWidget, Qt::Key_Escape);
QTest::keyClick(myWidget, Qt::Key_Escape, Qt::ShiftModifier, 200);</pre>
<p>The first example above simulates clicking the <tt>escape</tt> key on <tt>myWidget</tt> without any keyboard modifiers and without delay. The second example simulates clicking <tt>shift-escape</tt> on <tt>myWidget</tt> with a following 200 ms delay of the test.</p>

<p>This is an overloaded member function, provided for convenience.</p>
<p>Simulates clicking of <i>key</i> with an optional <i>modifier</i> on a <i>widget</i>. If <i>delay</i> is larger than 0, the test will wait for <i>delay</i> milliseconds.</p>
<p>Example:</p>

<h3 class="fn"><a name="newRow"></a>QTestData & QTest::newRow ( const char * <i>dataTag</i> )</h3>
<p>Appends a new row to the current test data. <i>dataTag</i> is the name of the testdata that will appear in the test output. Returns a QTestData reference that can be used to stream in data.</p>
<p>Example:</p>
<pre> void myTestFunction_data()
{
QTest::addColumn<QString>("aString");
QTest::newRow("just hello") << QString("hello");
QTest::newRow("a null string") << QString();
}</pre>
<p><b>Note:</b> This macro can only be used in a test's data function that is invoked by the test framework.</p>
<p>See <a href="qtestlib-tutorial2.html">Data Driven Testing</a> for a more extensive example.</p>
<p>See also <a href="qtest.html#addColumn">addColumn</a>() and <a href="qtest.html#QFETCH">QFETCH</a>().</p>
<h3 class="fn"><a name="qExec"></a>int QTest::qExec ( <a href="qobject.html">QObject</a> * <i>testObject</i>, int <i>argc</i> = 0, char ** <i>argv</i> = 0 )</h3>
<p>Executes tests declared in <i>testObject</i>. In addition, the private slots <tt>initTestCase()</tt>, <tt>cleanupTestCase()</tt>, <tt>init()</tt> and <tt>cleanup()</tt> are executed if they exist. See <a href="qtestlib-manual.html#creating-a-test">Creating a test</a> for more details.</p>
<p>Optionally, the command line arguments <i>argc</i> and <i>argv</i> can be provided. For a list of recognized arguments, read <a href="qtestlib-manual.html#qtestlib-command-line-arguments">QTestLib Command Line Arguments</a>.</p>
<p>For stand-alone tests, the convenience macro <a href="qtest.html#QTEST_MAIN">QTEST_MAIN</a>() can be used to declare a main method that parses the command line arguments and executes the tests.</p>
<p>The following example will run all tests in <tt>MyFirstTestObject</tt> and <tt>MySecondTestObject</tt>:</p>
<pre> MyFirstTestObject test1;
QTest::qExec(&test1);
MySecondTestObject test2;
QTest::qExec(&test2);</pre>
<p>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.</p>
<p>See also <a href="qtest.html#QTEST_MAIN">QTEST_MAIN</a>().</p>
<h3 class="fn"><a name="qSleep"></a>void QTest::qSleep ( int <i>ms</i> )</h3>
<p>Sleeps for <i>ms</i> 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 <a href="qtest.html#qWait">qWait</a>() to do non-blocking sleeping.</p>
<p><i>ms</i> must be greater than 0.</p>
<p><b>Note:</b> The qSleep() function calls either <tt>nanosleep()</tt> on unix or <tt>Sleep()</tt> on windows, so the accuracy of time spent in qSleep() depends on the operating system.</p>
<p>Example:</p>
<pre> QTest::qSleep(250);</pre>
<p>See also <a href="qtest.html#qWait">qWait</a>().</p>
<h3 class="fn"><a name="qWait"></a>void QTest::qWait ( int <i>ms</i> ) <tt> [static]</tt></h3>
<p>Waits for <i>ms</i> milliseconds. While waiting, events will be processed and your test will stay responsive to user interface events or network communication.</p>
<p>Example:</p>
<pre> int i = 0;
while (myNetworkServerNotResponding() && i++ < 50)
QTest::qWait(250);</pre>
<p>The code above will wait until the network server is responding for a maximum of about 12.5 seconds.</p>
<p>See also <a href="qtest.html#qSleep">QTest::qSleep</a>().</p>
<h3 class="fn"><a name="toString"></a>char * QTest::toString ( const T & <i>value</i> )</h3>
<p>Returns a textual representation of <i>value</i>. This function is used by <a href="qtest.html#QCOMPARE">QCOMPARE</a>() to output verbose information in case of a test failure.</p>
<p>You can add specializations of this function to your test to enable verbose output.</p>
<p><b>Note:</b> The caller of toString() must delete the returned data using <tt>delete[]</tt>. Your implementation should return a string created with <tt>new[]</tt> or <a href="qbytearray.html#qstrdup">qstrdup</a>().</p>
<p>Example:</p>
<pre> 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());
}
}</pre>
<p>The example above defines a toString() specialization for a class called <tt>MyPoint</tt>. Whenever a comparison of two instances of <tt>MyPoint</tt> fails, <a href="qtest.html#QCOMPARE">QCOMPARE</a>() will call this function to output the contents of <tt>MyPoint</tt> to the test log.</p>
<p>See also <a href="qtest.html#QCOMPARE">QCOMPARE</a>().</p>

<h2>Macro Documentation</h2>
<h3 class="fn"><a name="QCOMPARE"></a>QCOMPARE ( <i>actual</i>, <i>expected</i> )</h3>
<p>The QCOMPARE macro compares an <i>actual</i> value to an <i>expected</i> value using the equals operator. If <i>actual</i> and <i>expected</i> are identical, execution continues. If not, a failure is recorded in the test log and the test won't be executed further.</p>
<p>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.</p>
<p><b>Note:</b> QCOMPARE is very strict on the data types. Both <i>actual</i> and <i>expected</i> have to be of the same type, otherwise the test won't compile. This prohibits unspecified behavior from being introduced; that is behavior that usually occurs when the compiler implicitely casts the argument.</p>
<p>Note that, for your own classes, you can use <a href="qtest.html#toString">QTest::toString</a>() to format values for outputting into the test log.</p>
<p><b>Note:</b> This macro can only be used in a test function that is invoked by the test framework.</p>
<p>Example:</p>
<pre> QCOMPARE(QString("hello").toUpper(), QString("HELLO"));</pre>
<p>See also <a href="qtest.html#QVERIFY">QVERIFY</a>() and <a href="qtest.html#toString">QTest::toString</a>().</p>
<h3 class="fn"><a name="QEXPECT_FAIL"></a>QEXPECT_FAIL ( <i>dataIndex</i>, <i>comment</i>, <i>mode</i> )</h3>
<p>The QEXPECT_FAIL() macro marks the next <a href="qtest.html#QCOMPARE">QCOMPARE</a>() or <a href="qtest.html#QVERIFY">QVERIFY</a>() as an expected failure. Instead of adding a failure to the test log, an expected failure will be reported.</p>
<p>If a <a href="qtest.html#QVERIFY">QVERIFY</a>() or <a href="qtest.html#QCOMPARE">QCOMPARE</a>() is marked as an expected failure, but passes instead, an unexpected pass (XPASS) is written to the test log.</p>
<p>The parameter <i>dataIndex</i> describes for which entry in the test data the failure is expected. Pass an empty string (<tt>""</tt>) if the failure is expected for all entries or if no test data exists.</p>
<p><i>comment</i> will be appended to the test log for the expected failure.</p>
<p><i>mode</i> is a <a href="qtest.html#TestFailMode-enum">QTest::TestFailMode</a> and sets whether the test should continue to execute or not.</p>
<p><b>Note:</b> This macro can only be used in a test function that is invoked by the test framework.</p>
<p>Example 1:</p>
<pre> QEXPECT_FAIL("", "Will fix in the next release", Continue);
QCOMPARE(i, 42);
QCOMPARE(j, 43);</pre>
<p>In the example above, an expected fail will be written into the test output if the variable <tt>i</tt> is not 42. If the variable <tt>i</tt> is 42, an unexpected pass is written instead. The QEXPECT_FAIL() has no influence on the second <a href="qtest.html#QCOMPARE">QCOMPARE</a>() statement in the example.</p>
<p>Example 2:</p>
<pre> QEXPECT_FAIL("data27", "Oh my, this is soooo broken", Abort);
QCOMPARE(i, 42);</pre>
<p>The above testfunction will not continue executing for the test data entry <tt>data27</tt>.</p>
<p>See also <a href="qtest.html#TestFailMode-enum">QTest::TestFailMode</a>, <a href="qtest.html#QVERIFY">QVERIFY</a>(), and <a href="qtest.html#QCOMPARE">QCOMPARE</a>().</p>
<h3 class="fn"><a name="QFAIL"></a>QFAIL ( <i>message</i> )</h3>
<p>This macro can be used to force a test failure. The test stops executing and the failure <i>message</i> is appended to the test log.</p>
<p><b>Note:</b> This macro can only be used in a test function that is invoked by the test framework.</p>
<p>Example:</p>
<pre> if (sizeof(int) != 4)
QFAIL("This test has not been ported to this platform yet.");</pre>
<h3 class="fn"><a name="QFETCH"></a>QFETCH ( <i>type</i>, <i>name</i> )</h3>
<p>The fetch macro creates a local variable named <i>name</i> with the type <i>type</i> on the stack. <i>name</i> has to match the element name from the test's data. If no such element exists, the test will assert.</p>
<p>Assuming a test has the following data:</p>
<pre> 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;
}</pre>
<p>The test data has two elements, a <a href="qstring.html">QString</a> called <tt>aString</tt> and an integer called <tt>expected</tt>. To fetch these values in the actual test:</p>
<pre> void TestQString::toInt()
{
QFETCH(QString, aString);
QFETCH(int, expected);
QCOMPARE(aString.toInt(), expected);
}</pre>
<p><tt>aString</tt> and <tt>expected</tt> are variables on the stack that are initialized with the current test data.</p>
<p><b>Note:</b> 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.</p>
<h3 class="fn"><a name="QSKIP"></a>QSKIP ( <i>description</i>, <i>mode</i> )</h3>
<p>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 <i>description</i> is appended to the test log and should contain an explanation why the test couldn't be executed. <i>mode</i> is a <a href="qtest.html#SkipMode-enum">QTest::SkipMode</a> and describes whether to proceed with the rest of the test data or not.</p>
<p><b>Note:</b> This macro can only be used in a test function that is invoked by the test framework.</p>
<p>Example:</p>
<pre> if (!QSqlDatabase::drivers().contains("SQLITE"))
QSKIP("This test requires the SQLITE database driver", SkipAll);</pre>
<p>See also <a href="qtest.html#SkipMode-enum">QTest::SkipMode</a>.</p>
<h3 class="fn"><a name="QTEST"></a>QTEST ( <i>actual</i>, <i>testElement</i> )</h3>
<p>QTEST() is a convenience macro for <a href="qtest.html#QCOMPARE">QCOMPARE</a>() that compares the value <i>actual</i> with the element <i>testElement</i> from the test's data. If there is no such element, the test asserts.</p>
<p>Apart from that, QTEST() behaves exactly as <a href="qtest.html#QCOMPARE">QCOMPARE</a>().</p>
<p>Instead of writing:</p>
<pre> QFETCH(QString, myString);
QCOMPARE(QString("hello").toUpper(), myString);</pre>
<p>you can write:</p>
<pre> QTEST(QString("hello").toUpper(), "myString");</pre>
<p>See also <a href="qtest.html#QCOMPARE">QCOMPARE</a>().</p>
<h3 class="fn"><a name="QTEST_APPLESS_MAIN"></a>QTEST_APPLESS_MAIN ( <i>TestClass</i> )</h3>
<p>Implements a main() function that executes all tests in <i>TestClass</i>.</p>
<p>Behaves like <a href="qtest.html#QTEST_MAIN">QTEST_MAIN</a>(), but doesn't instanciate a <a href="qapplication.html">QApplication</a> object. Use this macro for really simple stand-alone non-GUI tests.</p>
<p>See also <a href="qtest.html#QTEST_MAIN">QTEST_MAIN</a>().</p>
<h3 class="fn"><a name="QTEST_MAIN"></a>QTEST_MAIN ( <i>TestClass</i> )</h3>
<p>Implements a main() function that instanciates a <a href="qapplication.html">QApplication</a> object and the <i>TestClass</i>, and executes all tests in the order they were defined. Use this macro to build stand-alone executables.</p>
<p>Example:</p>
<pre> class TestQString: public QObject { ... };
QTEST_MAIN(TestQString)</pre>
<p>See also <a href="qtest.html#QTEST_APPLESS_MAIN">QTEST_APPLESS_MAIN</a>() and <a href="qtest.html#qExec">QTest::qExec</a>().</p>
<h3 class="fn"><a name="QTEST_NOOP_MAIN"></a>QTEST_NOOP_MAIN ()</h3>
<p>Implements a main() function with a test class that does absolutely nothing. Use this macro to create a test that produces valid test output but just doesn't execute any test, for example in conditional compilations:</p>
<pre> #ifdef Q_WS_X11
QTEST_MAIN(MyX11Test)
#else
<span class="comment">// do nothing on non-X11 platforms</span>
QTEST_NOOP_MAIN
#endif</pre>
<p>See also <a href="qtest.html#QTEST_MAIN">QTEST_MAIN</a>().</p>
<h3 class="fn"><a name="QVERIFY"></a>QVERIFY ( <i>condition</i> )</h3>
<p>The QVERIFY() macro checks whether the <i>condition</i> is true or not. If it is true, execution continues. If not, a failure is recorded in the test log and the test won't be executed further.</p>
<p><b>Note:</b> This macro can only be used in a test function that is invoked by the test framework.</p>
<p>Example:</p>
<pre> QVERIFY(1 + 1 == 2);</pre>
<p>See also <a href="qtest.html#QCOMPARE">QCOMPARE</a>().</p>
<h3 class="fn"><a name="QWARN"></a>QWARN ( <i>message</i> )</h3>
<p>Appends <i>message</i> as a warning to the test log. This macro can be used anywhere in your tests.</p>
<p><b>Note:</b> This function is <a href="threads.html#thread-safe">thread-safe</a>.</p>
