Learn Qt 5

Overview of this book

Qt is a mature and powerful framework for delivering sophisticated applications across a multitude of platforms. It has a rich history in the Linux world, is widely used in embedded devices, and has made great strides in the Mobile arena over the past few years. However, in the Microsoft Windows and Apple Mac OS X worlds, the dominance of C#/.NET and Objective-C/Cocoa means that Qt is often overlooked. This book demonstrates the power and flexibility of the Qt framework for desktop application development and shows how you can write your application once and deploy it to multiple operating systems. Build a complete real-world line of business (LOB) solution from scratch, with distinct C++ library, QML user interface, and QtTest-driven unit-test projects. This is a suite of essential techniques that cover the core requirements for most LOB applications and will empower you to progress from a blank page to shipped application.

DataDecorator tests

In Chapter 5, Data, we created various classes deriving from DataDecorator. Let's create companion test classes for each of those and test the following functionalities:

  • Object construction
  • Setting the value
  • Getting the value as JSON
  • Updating the value from JSON

In cm-tests/source/data, create the DateTimeDecoratorTests, EnumeratorDecoratorTests, IntDecoratorTests, and StringDecoratorTests classes.

Let’s begin with the simplest suite, IntDecoratorTests. The tests will be broadly similar across the suites, so once we’ve written one suite, we will be able to copy most of it across to the other suites and then supplement as necessary.


#include <QtTest>
#include <data/int-decorator.h> #include <test-suite.h>
