Overview of this book

C++ has evolved over the years and the latest release – C++20 – is now available. Since C++11, C++ has been constantly enhancing the language feature set. With the new version, you’ll explore an array of features such as concepts, modules, ranges, and coroutines. This book will be your guide to learning the intricacies of the language, techniques, C++ tools, and the new features introduced in C++20, while also helping you apply these when building modern and resilient software. You’ll start by exploring the latest features of C++, and then move on to advanced techniques such as multithreading, concurrency, debugging, monitoring, and high-performance programming. The book will delve into object-oriented programming principles and the C++ Standard Template Library, and even show you how to create custom templates. After this, you’ll learn about different approaches such as test-driven development (TDD), behavior-driven development (BDD), and domain-driven design (DDD), before taking a look at the coding best practices and design patterns essential for building professional-grade applications. Toward the end of the book, you will gain useful insights into the recent C++ advancements in AI and machine learning. By the end of this C++ programming book, you’ll have gained expertise in real-world application development, including the process of designing complex software.

Exploring unit testing, TDD, and BDD

We learned about automatic static and dynamic program analysis in the previous section. This section will focus on human-involved (preparing test code) tests, which are another part of dynamic analysis. These are unit testing, test-driven development, and behavior-driven development.

Unit testing assumes that if we already have a single unit of code, then we need to write a test driver and prepare input data to check if its output is correct. After that, we perform integration tests to test multiple units together, and then the acceptance tests, which test the entire application. Since the integration and acceptance tests are more difficult to maintain and more project-related than unit tests, it is very challenging to cover them in this book.
