Overview of this book

There’s a lot more to C than knowing the language syntax. The industry looks for developers with a rigorous, scientific understanding of the principles and practices. Extreme C will teach you to use C’s advanced low-level power to write effective, efficient systems. This intensive, practical guide will help you become an expert C programmer. Building on your existing C knowledge, you will master preprocessor directives, macros, conditional compilation, pointers, and much more. You will gain new insight into algorithm design, functions, and structures. You will discover how C helps you squeeze maximum performance out of critical, resource-constrained applications. C still plays a critical role in 21st-century programming, remaining the core language for precision engineering, aviations, space research, and more. This book shows how C works with Unix, how to implement OO principles in C, and fully covers multi-processing. In Extreme C, Amini encourages you to think, question, apply, and experiment for yourself. The book is essential for anybody who wants to take their C to the next level.

Testing libraries for C

In this section, we are going to demonstrate two of the well-known libraries used to write tests for C programs. For unit testing in C, we use libraries that are written in C or C++. That's because we can integrate them easily and use the units directly from a C or C++ testing environment. In this section, our focus is on unit testing and component testing in C.

For integration testing, we are free to choose other programming languages. Generally, the integration and system testing are much more complex, and we therefore need to use some testing automation frameworks in order to write tests easier and run them without too much hassle. Using a domain-specific language (DSL) is part of this automation, in order to write test scenarios more easily and make test execution much simpler. Many languages can be used for this purpose, but scripting languages like Unix shell, Python, JavaScript, and Ruby are among the most favorite ones. Some other programming...
