The document summarizes a presentation on MUnit testing in MuleSoft. It includes an agenda that covers an introduction to MUnit, the MUnit test recorder and parameterizations, and quizzes. The presentation discusses types of testing, how MUnit works, its sub-modules and scopes, how the test recorder captures test data and generates tests, and how to use parameterizations in tests through YAML and configuration XML. It concludes with a demo and final quiz questions.

8. Types of Testing

Unit Testing Integration Testing Perfomance Testing
Used to verify the
functionality of a specific
unit (i.e: flow or sublflow).
Used to verify that all of
the interactions are
functional with the systems
that the application
interacts with.
In this type of Testing both
input and output data are
validated when interacting
with external systems.
The main purpose of this
type of Testing is to verify
performance and behavior
of the systems and
environments as well as
scalability and usage of
resources under high load
work.

10. Scopes

MUnit test is divided in three scopes:
1- Behavior
Used to configure pre-conditions before the execution, mocks and spies.
2- Execution
Used to define the logic of the test, typically a Flow Reference.
3- Validation
Used to validate the results of the execution. Here you can add assertions and verifiers.

Anypoint Studio>= 7.5.0
Munit Test Recorder
Is a tool embedded in Anypoint Studio that allows us to record an entire
flow and with that recording configure a test based on such event.
❖ Captures real information as it passes through the
application.
❖ It allows us to create automatically a test in which you
can configure the mocks and assertions needed.

Allows to execute a request with multiple/different inputs. 3 methods can be used.
Method 1 - YAML
Method 2 – Paramaeter within config XML
1.- Create YAML under src/test/resources
2.- Reference to YAML from XML
3.- Reference to variable in behavior
Parameterizations
