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.

Component testing

As we explained in the previous section, units can be defined as a single function, a group of functions, or a whole component. Therefore, component testing is a special type of unit testing. In this section, we want to define a hypothetical component as part of example 22.1 and put the two functions found in the example into this component. Note that a component usually results in an executable or a library. We can suppose that our hypothetical component would result in a library that contains the two functions.

As we said before, we have to be able to test the functionality of a component. In this section, we still want to write test cases but the difference between the tests written in this section and the previous section is to do with the units that should be isolated. In the previous section, we had functions that should have been isolated, but in this section, we have a component, compromising of two functions working hand in hand, that needs to be isolated...
