Overview of this book

Despite the prevalence of higher-level languages, C++ is still running the world, from bare-metal embedded systems to distributed cloud-native systems. C++ is on the frontline whenever there is a need for a performance-sensitive tool supporting complex data structures. The language has been actively evolving for the last two decades. This book is a comprehensive guide that shows you how to implement SOLID principles and refactor legacy code using the modern features and approaches of C++, the standard library, Boost library collection, and Guidelines Support Library by Microsoft. The book begins by describing the essential elements of writing clean code and discussing object-oriented programming in C++. You’ll explore the design principles of software testing with examples of using popular unit testing frameworks such as Google Test. The book also guides you through applying automated tools for static and dynamic code analysis using Clang Tools. By the end of this book, you’ll be proficient in applying industry-approved coding practices to design clean, sustainable, and readable real-world C++ code.

Good candidates for unit tests

Identifying the optimal candidates for unit testing is pivotal in establishing a robust testing strategy. Unit tests excel when applied to parts of the code base that are well-suited to isolation and fine-grained verification. Here are some key examples and recommendations:

Classes and functions with clear boundaries and well-defined responsibilities are prime candidates for unit testing. These components should ideally embody the Single Responsibility Principle, handling a specific aspect of the application’s functionality. Testing these isolated units allows for precise verification of their behavior, ensuring that they perform their intended tasks correctly under various conditions.

Pure functions, which depend solely on their input parameters and produce no side effects, are excellent targets for unit tests. Their deterministic nature – where a given input always results in the same output – makes them straightforward to...
