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 12: Writing Testable Code

So far, in this book, our focus has been on writing test code. The LookupValue extension, our example case, came with application code mainly ready. As such we did not talk about how to get your application code better suited to being tested. We did not ask ourselves: what does it mean to write testable code?

In this chapter, we'll find an answer to this query based on the following questions:

  • What is testable code?
  • How to make your code testable?

As we have done in the previous chapters, we will go through a test example, Test example 11 – how to unit test event subscribers' logic, where we'll work out one of the techniques discussed.
