Test example 12 – testing incoming calls: Lookup Value API

With this example, you learn how to test getting (using GET), deleting (using DELETE), modifying (using PATCH), and creating (using POST) data through an API.

Note

In this example, we focus on the structure and code of the automated tests that test an API, not on the flow of getting from a customer wish into test and application coding and also not on doing it the TDD way.

Application code

The object for our tests is a new page called Lookup Values APIV1 (50090) with PageType set to API and SourceTable pointing to our Lookup Value table. This API contains three columns:

• id based on SystemId field
• number based on the Code field
• displayName based on the Description field

The full object can be seen in the GitHub repo: https://github.com/PacktPublishing/Automated-Testing-in-Microsoft-Dynamics-365-Business-Central-Second-Edition/blob/main/Chapter 13 (LookupValue Extension)/src/page/LookupValuesAPIV1...
