Writing Apex Tests

Writing Apex Tests

When developing against the API you will likely be doing one or more of the following types of API integrations:

  • Use Case 1: Calling an FFA API directly to perform a task
  • Use Case 2: Calling a Salesforce DML API directly to perform a record operation
  • Use Case 3: Implementing a custom Apex Trigger

This code sample illustrates how to setup a basic environment within an Apex Test, to allow this type of code to be covered and tested as per the platform requirements and best practices.
