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.

Executing your tests

We wrote a test case, TestJsonSerializer, with some test functions. We need a main() function in our drum-machine-test application. We will explore three possibilities:

  • The QTEST_MAIN() function
  • Writing our own simple main() function
  • Writing our own enhanced main() function that supports multiple test classes

The QTest module provides an interesting macro, QTEST_MAIN(). This macro generates a complete main() function for your application. This generated method runs all the test functions of your test case. To use it, add the following snippet at the end of the TestJsonSerializer.cpp file:

QTEST_MAIN(TestJsonSerializer) 

Moreover, if you declare and implement your test class only in the .cpp file (without a header file), you need to include the generated moc file after the QTEST_MAIN macro:

QTEST_MAIN(TestJsonSerializer) 
#include "testjsonserializer...
