Activate MUnit in a Maven build, select the intended tests and enforce explicit coverage requirements. Distinguish execution, environment configuration and diagnostic output across plugin versions.

- Certification: Salesforce MuleSoft Developer II
- Exam section: Implement maintainable and modular Mule applications and their Maven builds
- Study guide: https://www.certifyforce.com/study-guide/mulesoft-developer-ii

**Official exam objective:**

> Execute MUnit tests with Maven.

## What the exam expects

- Enable the MUnit plugin and its dependencies in a Mule application build.
- Activate managed plugin configuration in child projects.
- Select suites, named tests or tagged groups without confusing selectors.
- Distinguish missing tests, skipped tests and insufficient coverage.
- Control test properties, runtime selection and dynamic ports.
- Retain useful diagnostic output from automated test runs.

**Suite** is an XML collection of tests; **goal** is a plugin operation; **phase** is a Maven lifecycle stage; **coverage** measures executed application processors; **tag** groups tests; **system property** supplies a named value to the test run ([Test structure](https://docs.mulesoft.com/munit/2.3/munit-test-concept), [Plugin](https://docs.mulesoft.com/munit/2.3/munit-maven-plugin), [Coverage](https://docs.mulesoft.com/munit/2.3/coverage-maven-concept)).

## Key facts

| Fact | Detail | Source |
|---|---|---|
| Activation | Children reference the managed plugin under build plugins. | [Parent setup](https://docs.mulesoft.com/munit/2.3/munit-maven-plugin) |
| Named test selector | `#` separates suite and test expressions. | [Selectors](https://docs.mulesoft.com/munit/2.3/munit-maven-plugin) |
| Tag selection | Configure `munitTags` or use `munit.tags`. | [Tags](https://docs.mulesoft.com/munit/2.3/munit-maven-plugin) |
| Empty-run policy | Disabling no-test failure does not disable future test execution. | [Current contract](https://docs.mulesoft.com/munit/latest/munit-maven-plugin) |
| Undefined threshold | `-1` means no requirement at that coverage level. | [Coverage](https://docs.mulesoft.com/munit/2.3/coverage-maven-concept) |
| Failure enforcement | `failBuild` controls whether missed defined levels fail the build. | [Coverage](https://docs.mulesoft.com/munit/2.3/coverage-maven-concept) |
| Excluded coverage | Ignored flows do not contribute to measured processor totals. | [Exclusions](https://docs.mulesoft.com/munit/2.3/coverage-maven-concept) |
| Property priority | Same-named command-line `-D` values take priority. | [Properties](https://docs.mulesoft.com/munit/2.3/munit-maven-plugin) |

## Check yourself

- Why can test-result summaries remain visible after suite output redirection is enabled?
- When diagnostic files must follow the build directory, how can their destination be expressed?
- How can output not associated with a particular suite be exposed during diagnosis?
