This book is for developers, development managers, testers, functional consultants, and power users working with Microsoft Dynamics 365 Business Central or Dynamics NAV.
The reader is assumed to have a general understanding of Dynamics 365 Business Central as an application and how this application can be extended. Even though some sections will be dedicated to the coding of automated tests, it's not mandatory to be able to write code for Dynamics 365 Business Central. Overall, it sure gives the reader an advantage to be able to think as a tester.
