Overview of this book

Qt 5.11 is an app development framework that provides a great user experience and develops full capability applications with Qt Widgets, QML, and even Qt 3D. Whether you're building GUI prototypes or fully-fledged cross-platform GUI applications with a native look and feel, Mastering Qt 5 is your fastest, easiest, and most powerful solution. This book addresses various challenges and teaches you to successfully develop cross-platform applications using the Qt framework, with the help of well-organized projects. Working through this book, you will gain a better understanding of the Qt framework, as well as the tools required to resolve serious issues, such as linking, debugging, and multithreading. You'll start off your journey by discovering the new Qt 5.11 features, soon followed by exploring different platforms and learning to tame them. In addition to this, you'll interact with a gamepad using Qt Gamepad. Each chapter is a logical step for you to complete in order to master Qt. By the end of this book, you'll have created an application that has been tested and is ready to be shipped.

You Shall (Not) Pass with QTest

In the previous chapter, we created a drum machine software with some serialization features. In this chapter, we will write the unit tests for this application. Unit testing will help us to verify each part of the source code. We will easily be able to spot an error during software development. To achieve this goal, we will use Qt Test, a dedicated test module for Qt applications.

The example project is a test application using CLI commands to execute and generate a test report. We will cover different types of tests, including datasets, GUI, signals, and benchmarking.

In this chapter, we will cover the following topics:

  • Discovering Qt Test
  • Executing your tests
  • Writing factorized tests with datasets
  • Benchmarking your code
  • Testing your GUI
  • Spying on your application with QSignalSpy
