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 plugin business logic


Another byproduct of refactoring our code is rendering it unit-testing friendly. Separating the layers, especially the data access layer and the plugin entry, means that we now have a true business logic layer that is independent from connections to other systems. We can unit test this business logic as a standalone layer.

In our unit test, we will focus on behavior verification as opposed to state verification.

This unit test will not focus on the state of the records but rather verify that the correct methods were called the expected number of times and with the right parameters. We will follow the AAA pattern (Arrange, Act, Assert).

For a state verification unit test, look at the next recipe, Unit testing your plugin with in-memory context.

We will unit test the plugin business logic from the first recipe in this chapter. We will mock the IEmailDataAccessLayer DAL to return predefined values when the GetEmails method is called. We will stub ICustomTracingService...
