Chapter 11

1. Why would you like to test a Qt application?
   First of all, for correctness, and then for regression, and also for regressions in performance—remember Qt performance-regression tests and https://testresults.qt.io/grafana/?
2. How would you implement a performance-regression test measuring the FPS rate of a QML application?
   We already developed a graphical FPS display in Chapter 8, Optimizing Graphical Performance. We could use the same technique of hooking into signals emitted by the QML scene graph and computing the needed statistics.
3. Any ideas about deploying Qt application to embedded Linux? Take some hints from the previous chapter.
   As we discussed in the previous chapter, Qt Creator supports the copying of a cross-compiled binary to a target device. When the development is finished, the executable will be included as a separate packet in the Linux build tool...
