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

Controlling output with Catch


As with other testing frameworks discussed in this book, Catch reports the results of a test program execution in a human-readable format to the stdout standard stream. Additional options are supported, such as reporting using XML format or writing to a file. In this recipe, we will look at the main options available for controlling the output when using Catch.

Getting ready

To exemplify the way the test program's execution output could be modified, use the following test cases:

    TEST_CASE("case1")
    {
      SECTION("function1")
      {
        REQUIRE(true);
      }
    }

    TEST_CASE("case2")
    {
      SECTION("function2")
      {
        REQUIRE(false);
      }
    }

The output of running these two test cases is as follows:

----------------------------------------------------------
case2
  function2
----------------------------------------------------------
