Learning Objectives

After completing this unit, you'll be able to:

Use the Stub API to mock dependencies.
Inject a mock into the code under test.

Concepts

The Apex Stub API (System.StubProvider and Test.createStub) replaces a dependency with a mock, so you can test a class without touching the database or a callout.

Hands-On Challenge

Create a StubProvider implementation that returns a fixed account list.
Inject it into AccountService and assert the service handles the list.
