This book is an introduction to test automation for Dynamics 365 Business Central. On one hand, various concepts and terminology are discussed, and on the other hand, we will also practice them by coding tests. To get the most out of this book, you might want to practice what is preached by implementing the code examples discussed. As this book, however, does not cover how to program against Business Central, you might first want to read the tips given in Appendix B, Setting Up VS Code and Using the GitHub project.

If your learning style is to start by finding out the principles, terminology, and concepts, start reading Chapter 1, Introduction to Automated Testing, and move slowly into the more practical Section 3: Designing and Building Automated Tests for Microsoft Dynamics 365 Business Central. If your style is more learning by doing, you could dare to take a deep dive into Chapter 5, From Customer Wish to Test Automation - The Basics, Chapter 6, From Customer Wish to Test Automation - Next Level, and Chapter 7, From Customer Wish to Test Automation - And Some More, straight away, and read the various backgrounds later or while working through the chapters.

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The only step to be taken is to add the following code to the relevant Initialize function."

A block of code is set as follows:

fields
    {
        field(1; Code; Code[10]){}
        field(2; Description; Text[50]){}
    }

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

[FEATURE] LookupValue Customer 
[SCENARIO #0001] Assign lookup value to customer
[GIVEN] A lookup value
[GIVEN] A customer

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "Select System info from the Administration panel."
