Module 13 — MUnit

This is the module where your QA background gives you the biggest advantage.

MUnit is MuleSoft’s native testing framework for Mule applications. It supports unit/integration-style testing, mocking processors, assertions, verification of processor calls, tagging, and coverage reporting, and it integrates with Maven/Surefire for CI/CD.

The mental model is:

Arrange
↓
Act
↓
Assert

but in MUnit terms it often looks like:

Behavior
↓
Execution
↓
Validation
