Modern C++ Programming Cookbook - Second Edition

By: Marius Bancila

Overview of this book

C++ has come a long way to be one of the most widely used general-purpose languages that is fast, efficient, and high-performance at its core. The updated second edition of Modern C++ Programming Cookbook addresses the latest features of C++20, such as modules, concepts, coroutines, and the many additions to the standard library, including ranges and text formatting. The book is organized in the form of practical recipes covering a wide range of problems faced by modern developers. The book also delves into the details of all the core concepts in modern C++ programming, such as functions and classes, iterators and algorithms, streams and the file system, threading and concurrency, smart pointers and move semantics, and many others. It goes into the performance aspects of programming in depth, teaching developers how to write fast and lean code with the help of best practices. Furthermore, the book explores useful patterns and delves into the implementation of many idioms, including pimpl, named parameter, and attorney-client, teaching techniques such as avoiding repetition with the factory pattern. There is also a chapter dedicated to unit testing, where you are introduced to three of the most widely used libraries for C++: Boost.Test, Google Test, and Catch2. By the end of the book, you will be able to effectively leverage the features and techniques of C++11/14/17/20 programming to enhance the performance, scalability, and efficiency of your applications.

Getting started with Boost.Test

Boost.Test is one of the oldest and most popular C++ testing frameworks. It provides an easy-to-use set of APIs for writing tests and organizing them into test cases and test suites. It has good support for asserting, exception handling, fixtures, and other important features required for a testing framework.

Throughout the next few recipes, we will explore the most important features it has that enable you to write unit tests. In this recipe, we will see how to install the framework and create a simple test project.

Getting ready

The Boost.Test framework has a macro-based API. Although you only need to use the supplied macros for writing tests, a good understanding of macros is recommended if you want to use the framework well.

How to do it...

In order to set up your environment to use Boost.Test, do the following:

  1. Download the latest version of the Boost library from http://www.boost.org/.
  2. Unzip the content of...
