I love learning new things, and I hope you found some new things in this chapter. We started off in the Testing Qt applications section and learned multiple ways to test applications. In the Debugging Qt applications section, we looked at methods of debugging applications the old-school way and by using the Qt Creator debugging screens. Finally, we looked at monitoring Qt applications.
None of these were exhaustive looks. They were more of a survey to let you know what is out there. I encourage you to continue looking into these topics as you find the need for them.
In the next chapter, we will talk about responsive application programming using the Qt thread support libraries.
