+    \macro void Q_ASSERT(bool test)
+    \relates <QtAssert>
+
+    Prints a warning message containing the source code file name and
+    line number if \a test is \c false.
+
+    Q_ASSERT() is useful for testing pre- and post-conditions
+    during development. It does nothing if \c QT_NO_DEBUG was defined
+    during compilation.
+
+    Example:
+
+    \snippet code/src_corelib_global_qglobal.cpp 17
+
+    If \c b is zero, the Q_ASSERT statement will output the following
+    message using the qFatal() function:
+
+    \snippet code/src_corelib_global_qglobal.cpp 18
+
+    \sa Q_ASSERT_X(), qFatal(), {Debugging Techniques}
