This learning guide is based on the Unit Testing Succinctly eBook, by Marc Clifton, kindly provided by Syncfusion.

Unit testing can be a valuable part of any development cycle, but it can easily cause more problems than it prevents if used incorrectly. In this series, you'll learn what you need to know to leverage unit testing and minimize the number of bugs introduced in development. 

The series clearly defines what does and does not constitute units and tests, different approaches to implementing unit tests, and even the far-reaching effects that unit testing can have on the architecture of your application.
