Mastering Qt 5

Overview of this book

Qt 5.7 is an application development framework that provides a great user experience and develops full-capability applications with Qt Widgets, QML, and even Qt 3D. This book will address challenges in successfully developing cross-platform applications with the Qt framework. Cross-platform development needs a well-organized project. Using this book, you will have a better understanding of the Qt framework and the tools to resolve serious issues such as linking, debugging, and multithreading. Your journey will start with the new Qt 5 features. Then you will explore different platforms and learn to tame them. Every chapter along the way is a logical step that you must take to master Qt. The journey will end in an application that has been tested and is ready to be shipped.

Preface

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

  • Write our own simple main() function

  • Write our own enhanced main() supporting 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" 

If you use the QTEST_MAIN() macro, do not forget to remove the existing main.cpp. Otherwise, you will have two main() functions...
