Hands-On Embedded Programming with Qt

By: John Werner

Overview of this book

Qt is an open source toolkit suitable for cross-platform and embedded application development. This book uses inductive teaching to help you learn how to create applications for embedded and Internet of Things (IoT) devices with Qt 5. You’ll start by learning to develop your very first application with Qt. Next, you’ll build on the first application by understanding new concepts through hands-on projects and written text. Each project will introduce new features that will help you transform your basic first project into a connected IoT application running on embedded hardware. In addition to gaining practical experience in developing an embedded Qt project, you will also gain valuable insights into best practices for Qt development and explore advanced techniques for testing, debugging, and monitoring the performance of Qt applications. The examples and projects covered throughout the book can be run both locally and on an embedded platform. By the end of this book, you will have the skills you need to use Qt 5 to confidently develop modern embedded applications.

Testing Qt applications

There are two basic ways of verifying that code is functioning:

  • Inspection: Looking at the code to find errors
  • Testing: Running the code with multiple inputs and verifying the correct functionality

In this chapter, we will learn about both the strategies and the tools Qt brings to the table to help with them. We will also talk a little about the importance of code coverage for any verification or testing effort.

Some may break this into two parts for each category I listed—Inspection and Analysis and Testing and Demonstration. Personally, I feel that just confuses things. You can either inspect the code, including analyzing the logic/calculations, or you can test the code, which is really just a demonstration that it works.

We will start with code analysis because Qt makes it so easy to do some of the work.
