Catch bugs early with automated API testing.
Unit testing software for APIs and MuleSoft apps that integrates seamlessly with existing workflows.
Unit test before deploying.
Test your Mule applications and APIs before going live using MUnit, our built-in testing tool, to make sure they work reliably and perform well.
Test faster with easy integration.
Generate tests and coverage reports automatically by adding MUnit testing to your existing CI/CD process, so you spend less time on manual work.
Run tests on local servers.
Use local servers like DB/FTP/mail to test anywhere during development. Design and test your apps visually or in XML code right in Anypoint Code Builder.
Easy built-in testing tool for Anypoint Code Builder.
Build MUnit tests using a visual interface, code editing, or AI within Anypoint Code Builder. Use the built-in tools and debugger to save time and generate coverage reports all in one place, so you don’t have to switch between different tools or learn new interfaces.
Integrate with popular tools you already use.
Add testing easily to your existing CI/CD development pipeline. MUnit works with popular tools like Maven, Jenkins, Surefire, and SonarQube, so it fits right into your current setup without extra configuration.
Auto-generate tests from your API specs with AI.
MUnit can automatically create tests from your RAML files using built-in generative AI to help you build tests faster. It uses the data types from RAML files to create validation test data and allows you to customize or extend any of the generated tests as needed.
Test locally without needing to install servers.
MUnit includes built-in utility tools for testing with local FTP, database, and mail servers. This means you don’t need to install separate servers or connect to external systems during testing, making them work anywhere.
Get one-click coverage reports to track progress.
Generate coverage reports with one click to see resources covered in the text, flow coverage, and how much of your application has been tested. You can also export reports as JSON to use with your own reporting tools.

MUnit Frequently Asked Questions
Unit testing software is a tool that automatically tests individual pieces of code to catch bugs early. It runs small, focused tests on specific functions to make sure they work correctly. This lets developers write tests once and run them repeatedly as they make changes, ensuring new updates don’t break existing code and giving confidence before going live.
MUnit is MuleSoft’s testing framework for creating and running unit and integration tests for Mule applications. It allows developers to validate flows, subflows, and data transformations before deploying to production.
MUnit ensures your integrations and APIs behave as expected. It helps catch bugs early, supports regression testing, and improves confidence in deployments across environments like Dev, Test, and Prod.
MUnit lets you test individual flows, components like connectors and transformers, error handling, and DataWeave scripts. MUnit also supports mocking, spying, and verifying behavior across flows.
MUnit tests can be written manually in XML within your Mule project or generated using tools like Anypoint Code Builder. It offers AI-assisted test generation, helping accelerate setup and improve test coverage.
MUnit provides a mock-when feature that lets you mock connectors, flows, and components. This allows you to isolate the logic under test and avoid external dependencies during execution.
MUnit ests can be run locally using Anypoint Code Builder or Studio, via Maven commands, or as part of a CI/CD pipeline. Results can be viewed in reports, the IDE, or exported in JUnit-compatible formats.
Yes. While primarily a unit testing tool, MUnit can simulate multiple parts of a flow and test integrations between services, especially when paired with mock data and controlled environments.
MUnit generates code coverage reports showing how much of your Mule application was exercised during testing. This helps identify untested logic and improve overall test completeness.
MUnit tests can be run during CI/CD builds using Maven plug-ins or command-line scripts. Test results and coverage reports can be integrated into dashboards like Jenkins, GitHub Actions, or GitLab.
In Anypoint Code Builder, AI can assist with test generation, suggest mocks, auto-complete assertions, and help identify common testing gaps. This reduces manual effort and helps maintain consistent quality across teams.
