Description

Modern, standard C++ is all that is needed to create a small and practical testing framework that will improve the design of any project. This allows you to think about how the code will be used, which is the first step in designing intuitive interfaces. TDD is a modern balanced software development approach that helps to create maintainable applications, provide modularity in design, and write minimal code that drastically reduces defects. With the help of this book, you'll be able to continue adding value when designs need to change by ensuring that the changes don't break existing tests. In this book, you will use test-driven development (TDD) to gain practical skills by writing a simple testing framework and then using it to drive the design of a logging library. The book will help you enhance your software development skills with test cases. You'll understand how to design and implement test cases. The chapters will also show you how to utilize the TDD approach to be more productive in software development than attempting to code in large unstructured steps. By the end of this book, you'll have gained knowledge of TDD and testing and also built a working logging library with unique features not found in other libraries.

What you will learn

Understand how to develop software using TDD

Keep the code for the system as error-free as possible

Refactor and redesign code confidently

Communicate the requirements and behaviors of the code with your team

Understand the differences between unit tests and integration tests

Use TDD to create a minimal viable testing framework

What is custom duty/charge?

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order?

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges?

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

The book takes you from an empty project, it doesn't use any libraries, it makes the reader build one and use the TDD methodology on the library itself (and on other projects in other chapters). It's very interesting to see what all the test macros generate and what is happening behind the scenes. As a bonus, the reader has the opportunity to learn some modern C++ concepts that they might not know, which are also explained pretty well. I was honored to do the technical review part of this book.

Howard Lee Harkness May 05, 2023

I was personally disappointed in the approach the author used in the beginning of the book. The introductory material might make a good college text for "How to Build a Unit Test Framework," but only tangentially addressed how to write good, meaningful, unit tests. It's a bit like writing about how to write a compiler -- probably good to understand the general principals, but very few programmers will actually write (or even work on) a compiler. If not for the slow beginning, I probably would have given this book 5 stars instead of 4.It wasn't until chapter 8 (What Makes a Good Test?) that the author started to focus on how to write good unit tests. I consider chapter 8 to be the best chapter of the book, followed by chapters 12 (Creating Better Test Confirmations) and 13 (How to Test Floating-Point and Custom Values), where the author wrote about some theory behind constructing meaningful (and readable) unit tests, and a bit about the TDD process in general.The last third or so of the book was the most valuable (to me, anyway). I particularly like the treatment the author gave to unit testing of multi-threaded code.
