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

Using fixtures in Boost.Test


The larger a test module is and the more similar test cases are, the more likely it is to have test cases that require the same setup, cleanup, and maybe the same data. A component that contains these is called a test fixture or test context. Boost.Test provides several ways to define test fixtures for a test case, test suite, or a module (globally). In this recipe, we will look at how fixtures work.

Getting ready

The examples in this recipe use the following classes and functions for specifying test unit fixtures:

    struct standard_fixture
    {
      standard_fixture()  {BOOST_TEST_MESSAGE("setup");}
      ~standard_fixture() {BOOST_TEST_MESSAGE("cleanup");}
      int n {42};
    };

    struct extended_fixture
    {
      std::string name;
      int data;

      extended_fixture(std::string const & n = "") : name(n), data(0) 
      {
        BOOST_TEST_MESSAGE("setup "+ name);
      }

      ~extended_fixture()
      {
        BOOST_TEST_MESSAGE("cleanup...
