Unit testing in C++

Unit tests are a foundational aspect of TDD in software engineering, playing a pivotal role in the C++ development process. They focus on validating the smallest sections of code, known as units, which are typically individual functions, methods, or classes. By testing these components in isolation, unit tests ensure that each part of the software behaves as intended, which is crucial for the system’s overall functionality.

In the TDD framework, unit tests take on an even more significant role. They are often written before the actual code, guiding the development process and ensuring that the software is designed with testability and correctness in mind from the outset. This approach to writing unit tests before the implementation helps in identifying bugs early in the development cycle, allowing for timely corrections that prevent the bugs from becoming more complex or affecting other parts of the system. This proactive bug detection not only saves time...
