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.

Chapter 3: The Testability Framework

Having discussed the why, when, what, and a first, general how of test automation, it's time to turn our focus fully to Business Central. In this chapter, we will discuss how Business Central facilitates you to write and execute automated tests. The specific feature that enables this is called the testability framework.

The testability framework was introduced in the platform with Dynamics NAV 2009 Service Pack 1. For the first time, developers were able to build test scripts in C/AL code and run them in the client. At that time, however, you could only program headless tests; that is, tests that do not use the user interface (UI) to trigger the business logic. The testability framework was a follow-up to an internal tool called the NAV Test Framework (NTF) and had been used and worked on for a couple of years already.

NTF allowed tests to be programmed in C# and ran against the Dynamics NAV UI. It was a neat system, with a neat technical...
