This document summarizes an agenda for a Mulesoft meetup event discussing MUnit testing. The event includes introductions, presentations on getting started with Mulesoft and MUnit testing, and a quiz with prizes. The MUnit testing presentation will cover what MUnit is, how to use it, common operations like assertions, and the new test recorder feature which can automatically generate tests. The goal is to make testing easier in Mulesoft. The event will conclude with calls for future speaker nominations and feedback.

• MUnit is the Mule application testing framework that enables developers to create,
design, and run unit and integration tests on Mule applications created within Anypoint
Studio.
• It natively supports unit and integration testing on APIs and Mule apps in local and
CI/CD environments (via Maven).
Note: If this is your first time learning about MUnit, check out our tutorial on how to create your first MUnit
test in Anypoint Studio.
• Further we will learn how the MUnit test recorder works and how it can simplify the
testing process.
• The test recorder allows us to create tests for our application without the need of
writing any code, empowering us to build more robust applications and ensure their
quality to meet any test coverage requirements.
What is MUnit and Test Recorder?

What is MUnit?

MUnit is divided into two
main sub-modules, one is
called MUnit and the other
MUnit Tools. Additionally,
there are Utilities available
for import such as a
Database Server, FTP
Server, or a Run and Wait
Scope. Here is an overview
of some of the different
MUnit features that you
can implement into your
unit testing.

How do you use MUnit?
• Use MUnit to build
test flows (technically
called test suites in
the industry) focused
on executing Mule
flows. Each test is
essentially a Mule
flow.
• Use components from
MUnit and generic
Mule components to
build test flows.
• Test flows execute in
a Mule runtime and
report results.

• A test flow is broken down into three sections:
1. Execution,
2. Behavior and
3. Validation.
• The behavior scope sets all the preconditions before executing the
test logic. The execution scope contains the testing logic which will
wait for all processes to finish before executing the next scope. The
validation scope contains all the validations for the results of the
execution scope.

• Test: Creates a new test “flow” broken down into three sections: Execution, Behavior, and Validation. The
behavior scope sets all the preconditions before executing the test logic. The execution scope contains the
testing logic which will wait for all processes to finish before executing the next scope. The validation scope
contains all the validations for the results of the execution scope.
• Set Event: Allows you to define a Mule Event. Usually used at the beginning of an MUnit test to define the
first message to send to the flow being tested.
• Set null payload: Defines a null payload to test how your flow will handle a null value.
• After Suite: Runs after executing all of the MUnit tests and runs just once. For instance, let’s suppose you
have an MUnit Test Suite File with four tests. The code inside an MUnit After Suite, runs just once, after all
of your tests.
• After Test: Runs after executing an MUnit test. For instance, let’s suppose you have an MUnit Test Suite file
with four tests. The code inside an MUnit After Test runs after each of your four tests; it runs four times.
• Before Suite: Runs before executing all of the MUnit tests and runs just once. For example, suppose you
have an MUnit Test Suite file with four tests. The code inside an MUnit Before Suite runs just once, before all
of your four tests.
• Before Test: Runs before executing an MUnit test. For instance, let’s suppose you have an MUnit Test Suite
file with four tests. The code inside an MUnit Before test runs before each of your four tests; it runs four
times.
MUnit Operations:

• Assert That: Allows you to run assertions to validate the state of a Mule event, such as checking to see
if a payload equals a certain value.
• Fail: Useful in validating that a test should fail if that point is reached in the flow. The processor throws
a java.lang.AssertionError.
• Mock When: Use this processor to mock an event, such as sending a mock POST request with a
mocked payload.
• Run Custom: Allows you to assert the Mule event content against a custom assertion.
• Verify Call: Allows you to verify if a processor was called.
• Spy: Allows you to see what happens before and after an event processor is called in your Flow.
Usually, you will tell the Spy processor to run a set of instructions before and after the execution.

Generally available from April 30th 2020
• Automate test creation: Capture flow
execution with the new Munit test
recorder to automatically generate
tests.
• Scale with confidence: Leverage
runtime performance improvements for
more efficient code execution.
• Collaborate on API Specs: Pull and
update API specifications within Studio
and merge them back to Design Center.
