Qt Test provides classes for unit testing Qt applications and libraries. All public methods are in the QTest namespace. In addition, the QSignalSpy class provides easy introspection for Qt's signals and slots, and the QAbstractItemModelTester allows for non-destructive testing of item models.
Note: There is no binary compatibility guarantee for the Qt Test module. This means that an application that uses Qt Test is only guaranteed to work with the Qt version it was developed against. However, source compatibility is guaranteed.
