Modern C++ Programming Cookbook

Overview of this book

C++ is one of the most widely used programming languages. Fast, efficient, and flexible, it is used to solve many problems. The latest versions of C++ have seen programmers change the way they code, giving up on the old-fashioned C-style programming and adopting modern C++ instead. Beginning with the modern language features, each recipe addresses a specific problem, with a discussion that explains the solution and offers insight into how it works. You will learn major concepts about the core programming language as well as common tasks faced while building a wide variety of software. You will learn about concepts such as concurrency, performance, meta-programming, lambda expressions, regular expressions, testing, and many more in the form of recipes. These recipes will ensure you can make your applications robust and fast. By the end of the book, you will understand the newer aspects of C++11/14/17 and will be able to overcome tasks that are time-consuming or would break your stride while developing.

Preface

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, and 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:

    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 x) { x_ = x; return *this; }
      int y() const { return y_; }
      point3d& y(int const y) { y_ = y; return *this; }
      int z() const { return z_; }
...
