Should you migrate to Mule 4?
• For applications that have short
lifespans and set to retire before the
Mule 3.9 extended end-of-life
(currently March 2024), we can
migrate to Mule 3.9 and stay there.
• For applications with longer lifespans
and has plans for major updates, it is
better to migrate to the latest version
of Mule 4.

What is the Mule Migration Assistant?
• The Mule Migration Assistant (MMA) is a command line tool which
assists in the translation of a Mule 3 application into Mule 4.
• MMA will not do a 100% conversion.
• A conversion report is generated which gives details on what needs
to be manually adjusted
• MMA is open source

MMA Conversion Report
There are 3 sections in the generated conversion report
• Errors – components that were not converted by the tool and
require manual migration
• Warnings – items that may require manual intervention based on
certain Mule 3 features that are not in Mule 4
• Info – concerned about Mule 3 features that were removed or
changed to make use of Mule 4 improvements

MUnit Overview
• MUnit is a testing framework used to write unit tests for Mule
applications.
• It is fully integrated with Maven and Surefire for integration with
your continuous development environment.

35. All contents © MuleSoft Inc.
Pros of using MUnit
• You can test your Mule applications, graphically or in XML, all within
Anypoint Studio.
• Easily integrate testing into your existing CI/CD process.
• Minimize manual work with auto—generated tests and coverage
reports.
• Leverage local DB/FTP/mail servers to make testing more portable
through the CI process
• MUnit tests provide code coverage reports with metrics on how
much of a Mule application has been executed.

36. All contents © MuleSoft Inc.
Cons for not using MUnit
• Unit testing is done not only to check/test the current process of an
application, Mule applications without MUnit tests are prone to error
in the future updates.

MUnit Coverage Report
• The MUnit Coverage feature provides a measurement of how much
of a Mule application has been executed.
• It offers four types of reports:
– Console report
– HTML report
– JSON report
– Sonar report
• MUnit handles three different coverage levels
– Application
– Resource
– Flow

Why use MUnit Test Recorder?
• It makes the developer’s life easier that they don’t have to spend
much of their time in writing the MUnit tests.

Limitations
• Cannot generate tests for flows with Mule errors raised inside the flow or
even errors are handled by On Error Continue.
• Test will not be generated for the successful execution, but the result
does not reach its destination because the application is terminated.
• Mocking values resulting from parallel processes causes a mixture of real
and mocked data that compromises the execution of the processors that
follow in your test.
• It does not support cases in which the structure of the data being tested
changes inside the iteration.
• Recorder does not support mocking a message before or inside a Foreach
processor.
