421-frameworks-quarkus-testing-unit-tests
Use when you need to write fast unit tests for Quarkus applications — including pure tests with @ExtendWith(MockitoExtension.class), @QuarkusTest with @InjectMock for full CDI mock replacement, @InjectSpy for partial CDI bean mocking, REST Assured for resource-focused tests, @ParameterizedTest with @CsvSource / @MethodSource, QuarkusTestProfile for test-specific configuration overrides, and naming conventions (Test → Surefire, IT → Failsafe). For framework-agnostic Java use @131-java-testing-unit-testing. This should trigger for requests such as Add or improve unit tests in a Quarkus project; Reduce slow @QuarkusTest usage with Mockito-first tests; Add @InjectSpy partial mocking or QuarkusTestProfile configuration in Quarkus tests; Convert repeated test methods to @ParameterizedTest with @CsvSource or @MethodSource; Write fast pure unit tests for Quarkus services.

Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/jabrena/plinth --skill 421-frameworks-quarkus-testing-unit-tests- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads 421-frameworks-quarkus-testing-unit-tests automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
Quarkus Unit Testing
Apply fast testing strategies for Quarkus: Mockito-first, QuarkusTest when CDI wiring matters.
What is covered in this Skill?
- Pure JUnit 5 + Mockito without container boot (@ExtendWith(MockitoExtension.class))
- @QuarkusTest with @InjectMock for full CDI bean replacement
- @InjectSpy for partial mocking — real bean wrapped as spy, specific methods overridden
- REST Assured for HTTP-level @QuarkusTest resource tests
- @ParameterizedTest with @CsvSource (inline data) and @MethodSource (complex objects)
- QuarkusTestProfile and @TestProfile for test-specific configuration overrides
- Naming conventions: *Test → Surefire (fast phase), *IT → Failsafe (verify phase)
- When to escalate to integration tests (
@422)
Scope: Apply recommendations based on the reference rules and good/bad code examples.
Constraints
Compile before test refactors; verify the full suite after.
- MANDATORY: Run
./mvnw compileormvn compilebefore applying any change - PREREQUISITE: Project must compile before applying test improvements
- SAFETY: If compilation fails, stop immediately
- BLOCKING CONDITION: Compilation errors must be resolved by the user before proceeding
- VERIFY: Run
./mvnw clean verifyormvn clean verifyafter applying improvements - BEFORE APPLYING: Read the reference for detailed rules and examples
When to use this skill
- Add or improve unit tests in a Quarkus project
- Reduce slow @QuarkusTest usage with Mockito-first tests
- Add @InjectSpy partial mocking or QuarkusTestProfile configuration in Quarkus tests
- Convert repeated test methods to @ParameterizedTest with @CsvSource or @MethodSource
- Write fast pure unit tests for Quarkus services
Workflow
- Read reference and assess project context
Read references/421-frameworks-quarkus-testing-unit-tests.md and inspect the current project setup before proposing changes.
- Gather scope and decide target improvements
Identify requested outcomes, constraints, and the minimum safe set of changes to apply.
- Apply framework-aligned changes
Implement or refactor configuration/code following the reference patterns and project conventions.
- Run verification and report results
Execute appropriate build/tests and summarize what changed, what was verified, and any follow-up actions.
