The QtTest module provides classes for unit testing Qt applications and libraries. Applications that use Qt's unit testing classes need to be configured to be built against the QtTest module. To include the definitions of the module's classes, use the following directive:

    #include <QtTest>

To link against the module, add this line to your qmake`.pro` file:

    CONFIG += qtestlib

See the QTestLib Manual for a detailed introduction on how to use Qt's unit testing features with your applications.

The QtTest module is part of all Qt editions.
