In this chapter, we first learned how to test a Qt application, starting with the classic unit tests, their integration in Qt Creator, GUI test automation with Squish, and ending with performance regression testing. Then we had a look at the Qt application deployment problem and learned the difference between static and dynamic builds, the deployment support tools Qt has to offer, and the specific case of Windows deployment and installation.
This is the last chapter of the book, and I hope you enjoyed the ride. Maybe we didn't go deep enough into many topics, but, first, this was an intermediate-level book, and, second, you cannot go deep into everything, as some chapters could be expanded into entire books of their own. Hopefully, you can now see somehow more clearly through the mists of Qt and performance lands, and maybe you have even started to appreciate...
