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.

Test example 2 – a first positive-negative test

This test example does not relate to a new customer wish and no new application code but is complementary to our first test. It is a rainy path version of the same customer wish leading to a new scenario:

[FEATURE] LookupValue UT Customer
[SCENARIO #0002] Assign non-existing lookup value to customer
[GIVEN] Non-existing lookup value
[GIVEN] Customer
[WHEN] Set non-existing lookup value on customer
[THEN] Non existing lookup value error thrown

Test code steps

Let's reuse the recipe applied for test example 1.

You might already recall these are the steps to take, being our new tool, the 4-steps recipe:

  1. Create a test codeunit, with a name based on the FEATURE tag.
  2. Embed the customer wish into a test function with a name based on the SCENARIO tag.
  3. Write your test story, based on GIVEN, WHEN, and THEN tags.
  4. Construct your real code.
