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 Catch2

Catch2 is a multiparadigm testing framework for C++ and Objective-C. The name Catch2 follows on from Catch, the first version of the framework, which stands for C++ Automated Test Cases in Headers. It enables developers to write tests using either the traditional style of test functions grouped in test cases or the behavior-driven development (BDD) style with given-when-then sections. Tests are self-registered and the framework provides several assertion macros; out of these, two are used the most: one fatal, namely REQUIRE, and one non-fatal, namely CHECK. They perform expression decomposition of both the left-hand and right-hand side values, which are logged in case of failure. Unlike its first version, Catch2 no longer supports C++03. For the remaining recipes of this chapter, we will learn how to write unit tests using Catch2.

Getting ready

The Catch2 test framework has a macro-based API. Although you only need to use the supplied macros for...
