What this book covers
Chapter 1, Introduction to Automated Testing, introduces you to automated testing: why you would want to use it, what it exactly entails, and when you should use it.
Chapter 2, Test Automation and Test-Driven Development, gives a short description of what Test-Driven Development (TDD) is and points out parts that can be of value to your daily development practices too.
Chapter 3, The Testability Framework, elaborates on how Microsoft Dynamics 365 Business Central enables you to run automated tests, and what this so-called Testability Framework actually is by describing its five pillars.
Chapter 4, The Test Tools, Standard Tests, and Standard Test Libraries, introduces the testing tool that resides in Dynamics 365 Business Central and allows you to run tests. Alongside that, we will discuss the standard tests and test libraries that Microsoft provides with Dynamics 365 Business Central.
Chapter 5, Test Plan and Test Design, discusses a couple of concepts and design patterns that allow you to conceive your tests more effectively and efficiently.
Chapter 6, From Customer Wish to Test Automation – the Basics, teaches you – and allows you to practice, based on a business case – how to get from a customer's requirement to the implementation of automated tests. In this chapter, you will make use of standard test libraries and techniques discussed in the previous chapters. The examples in this chapter will teach you the basics of headless and UI testing, and how to handle a positive-negative test.
Chapter 7, From Customer Wish to Test Automation – Next Level, continues the business case from Chapter 6, From Customer Wish to Test Automation – the Basics, and introduces some more advanced techniques: how to make use of shared fixtures, how to parameterize tests, and how to handle UI elements and hand over variables to these so-called UI handlers.
Chapter 8, From Customer Wish to Test Automation – the TDD Way, elaborates on how you can get your (test) coding done the Test-Driven Development way, putting test first all the way. Meanwhile you'll get introduced to two more examples and continue with the same business case from the previous two chapters: how to go about testing a report and how to set up permission testing.
Chapter 9, How to Integrate Test Automation in Daily Development Practice, discusses a number of best practices that might turn out to be beneficial for you and your team in getting test automation up and running in your day-to-day work.
Chapter 10, Getting Business Central Standard Tests Working on Your Code, discusses why you would want to use the standard test collateral Microsoft provides with Dynamics 365 Business Central, and how to fix errors when standard tests fail due to your extension of the standard application.
Chapter 11, How to Construct Complex Scenarios, shows you how to go about getting automated tests in place for complex scenarios, how to create reusable parts for them, and how to make use of already existing helper functions in the Microsoft test libraries.
Chapter 12, Writing Testable Code, introduces the concept of testable code: how to get your application code better suited to be tested with automated tests.
Chapter 13, Testing Incoming and Outgoing Calls, discusses how to test features that communicate with external systems, either being called from or calling on the outside world.
Appendix, Getting Up and Running with Business Central, VS Code, and the GitHub Project, pays attention to VS Code and AL development, and the code examples to be found in the repository on GitHub.
