A Guide to Successful Unit Testing
A Guide to Successful Unit Testing
For your next embedded project, here is a guide to getting the right results from your unit tests.
About the Book
This book will guide you through the concept of applying unit tests to your project. It starts by showing why unit test is not only needed, but why it will help your project as a whole to succeed. It also touches on good software engineering concepts which unit test is a key part of.
This book will guide you to look for the key indicators on code that is tested correctly, also on indicators that your code is behaving correctly. So when it is integrated into the rest of your software, you will be confident that any errors in that code is minimised.
This book is tool agnostic, and will provide a list of characterstics to look during your tool selection.
This book will show several strategies on how embedded system code can be tested using mock objects.
