SoC and the Apex Common Library Tutorial Series Part 17: Implementing Unit Tests with the Apex Mocks Library

ByCoding With The Force Inc

What is Apex Mocks? Apex Mocks is unit test mocking framework for Apex that was inspired by the very popular Java Mockito framework. The Apex Mocks framework is also built using Salesforce’s Stub API which is a good thing, there are mocking frameworks in existence that do not leverage the Stub API… you shouldn’t use…

SoC and the Apex Common Library Tutorial Series Part 16: Unit Test Mocks with Separation of Concerns

ByCoding With The Force Inc

How does Unit Testing fit into Separation of Concerns? The answer to this is simple, without Separation of Concerns, there is no unit testing, it just simply isn’t possible. To unit test you need to be able to create stub (mock) classes to send into your class you are testing via dependency injection (or through…

ByCoding With The Force Inc

What is Unit Testing? Unit Testing, is a way to test the logic in one class and ONLY one class at a time. Most classes in your system at some point do one of the following: 1) Call to another class to get some work done. 2) Query the database directly in the class. 3)…

ByCoding With The Force Inc

The Template for every Selector Class you create Every Selector layer class you create should at least implement the following methods for it to work as anticipated. The fflib_SObjectSelector Constructor Parameters and what each of them mean When you create a Selector class that extends the fflib_SObjectSelector class you have the option to send some…

ByCoding With The Force Inc

What is the Selector Layer The Selector Layer is Salesforce is based off Martin Fowler’s Data Mapper Layer concept. It’s, “a layer of Mappers that moves data between objects and a database while keeping them independent of each other and the Mapper itself”. In most tech stacks when you want to represent records in a…
