Automated Testing in Microsoft Dynamics 365 Business Central - Second Edition

Overview of this book

Dynamics 365 Business Central is a cloud-based SaaS ERP proposition from Microsoft. With development practices becoming more formal, implementing changes or new features is not as simple as it used to be back when Dynamics 365 Business Central was called Navigator, Navision Financials, or Microsoft Business Solutions-Navision, and the call for test automation is increasing. This book will show you how to leverage the testing tools available in Dynamics 365 Business Central to perform automated testing. Starting with a quick introduction to automated testing and test-driven development (TDD), you'll get an overview of test automation in Dynamics 365 Business Central. You'll then learn how to design and build automated tests and explore methods to progress from requirements to application and testing code. Next, you'll find out how you can incorporate your own as well as Microsoft tests into your development practice. With the addition of three new chapters, this second edition covers in detail how to construct complex scenarios, write testable code, and test processes with incoming and outgoing calls. By the end of this book, you'll be able to write your own automated tests for Microsoft Business Central.

The five pillars of the testability framework

In the following five sections, each pillar will be discussed and illustrated with a simple code example. Feel free to try them out yourself with or without the GitHub code examples. Being a hands-on book, we will get to a lot more relevant examples later on.

Pillar 1 – Test codeunits and test functions

Goal: Understand what test codeunits and test functions are and learn how to build and apply them.

The foremost important pillar of the testability framework is the concept of test codeunits and test functions.

Test codeunits

With test codeunits, we can create a suite of tests, with each test implemented as a so-called test function. The basics of a test codeunit are similar to a standard codeunit. You can set up its OnRun trigger, declare variables, and define functions in it. To make a codeunit a test codeunit, you need to set its Subtype to Test. Let's set up our first test codeunit:
