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.

Situations favoring E2E testing

Complex interactions

In situations where the application’s components engage in intricate interactions, possibly spanning different technologies and platforms, unit tests might fall short. E2E testing is indispensable for ensuring that the collective behavior of these components aligns with the expected outcomes, especially in:

The architecture outlined in the diagram represents a typical web application with several interconnected services, each serving a distinct role in the system.

At the frontend, there’s a user UI, which is the graphical interface where users interact with the application. It’s designed to send and receive data to and from the backend services through an API gateway. The API gateway acts as an intermediary that routes requests from the user UI to the appropriate backend services and aggregates responses to send back to the UI.

Several backend...
