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.

Writing and invoking tests with Boost.Test

The library provides both an automatic and manual way of registering test cases and test suites to be executed by the test runner. Automatic registration is the simplest way because it enables you to construct a test tree just by declaring test units. In this recipe, we will see how to create test suites and test cases using the single-header version of the library, as well as how to run tests.

Getting ready

To exemplify the creation of test suites and test cases, we will use the following class, which represents a three-dimensional point. This implementation contains methods for accessing the properties of a point, comparison operators, a stream output operator, and a method for modifying the position of a point:

class point3d
{
  int x_;
  int y_;
  int z_;
public:
  point3d(int const x = 0, 
          int const y = 0, 
          int const z = 0):x_(x), y_(y), z_(z) {}
  int x() const { return x_; }
  point3d& x(int const...
