Microsoft Dynamics 365 Extensions Cookbook

Overview of this book

Microsoft Dynamics 365 is a powerful tool. It has many unique features that empower organisations to bridge common business challenges and technology pitfalls that would usually hinder the adoption of a CRM solution. This book sets out to enable you to harness the power of Dynamics 365 and cater to your unique circumstances. We start this book with a no-code configuration chapter and explain the schema, fields, and forms modeling techniques. We then move on to server-side and client-side custom code extensions. Next, you will see how best to integrate Dynamics 365 in a DevOps pipeline to package and deploy your extensions to the various SDLC environments. This book also covers modern libraries and integration patterns that can be used with Dynamics 365 (Angular, 3 tiers, and many others). Finally, we end by highlighting some of the powerful extensions available. Throughout we explain a range of design patterns and techniques that can be used to enhance your code quality; the aim is that you will learn to write enterprise-scale quality code.

Unit testing your JavaScript


Nowadays, automated unit testing has become the norm on most projects. Unit testing is not only great at ensuring that your code is repeatedly and thoroughly tested, but it also provides a safety harness against future changes that might break your code. Furthermore, unit testing helps you improve code structure quality by building loosely coupled modules.

In this recipe, we will write a Visual Studio unit test for our Dynamics 365 JavaScript extension. More specifically, we will unit test the first JavaScript library we built in this chapter. We will check whether the conditions are correct and that the set value is called once on the postgraduatestartdate attribute. Given that the unit tests will run from Visual Studio with a fake Xrm.Page library, we won't need access to Dynamics 365.

Getting ready

Unlike managed .NET code unit tests, JavaScript unit testing requires a bit of preparation to get up and running. There are a few parts to your setup: you will need...
