Apex Trigger Series Video 3: Set Case Priority Based on Origin + Test Class

Welcome to Video 3 of the Apex Trigger Series, where we continue to strengthen your Salesforce Apex Trigger skills with practical, real-world scenarios along with deployable test classes for each solution.

In this video, we tackle an important Case management automation scenario:

✅ Scenario:
Whenever a Case record is created, check its Origin field:

If Origin = Phone, set Priority to High

Else, set Priority to Low

This ensures your support team prioritizes cases efficiently based on how customers reach out.

🔍 Key Concepts Covered in This Video:
✔️ Writing an Apex Trigger on Case (Before Insert)
✔️ Implementing if-else logic for field updates based on conditions
✔️ Creating a Test Class for the trigger:

Generating test case records with different origins

Asserting that Priority is set correctly based on the Origin field value

✔️ Best practices for writing clean, efficient, and bulk-safe triggers

This video is ideal for Salesforce Developers, Admins, and learners who want to build confidence in Apex by solving real business scenarios with proper test coverage.
