Hi i added this two libraries:
#include <QtTest> try to #include <QtTest/QTest>
QT+=testlib in project
Not seems to work so. A not lot of time was working it's very strange.
@Jeronimo You should really explain better what the problem is.
Your application builds, right? Does it start? If it starts is there anything in "Application Output" (I assume you're using QtCreator)?
