java-unit-test
Generate Java Unit Tests
Java teams often need focused tests that match existing project style. This skill guides Claude, Codex, and Claude Code to create JUnit and Mockito tests with practical mocks.
Install with my Agent
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "java-unit-test" from https://skillstore.io/skills/gavin-ali-java-unit-test.md and its manifest at https://skillstore.io/api/skills/gavin-ali-java-unit-test/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.

Test it
Using "java-unit-test". A payment service with repository and gateway dependencies.
Expected outcome:
- A test plan covering successful payment, declined payment, repository failure, and invalid amount cases.
- A Mockito-based test class structure with mocks, setup, focused assertions, and interaction checks.
Using "java-unit-test". A coverage report showing missed null and empty-list branches.
Expected outcome:
- Additional boundary tests for null input, empty collections, and dependency exceptions.
- Notes about weak assertions and any branches that need clearer product behavior.
Security Audit
SafeThe static dynamic import finding is a false positive caused by prose about Java static imports. The entropy heuristic is also a false positive because SKILL.md is readable Markdown guidance, not binary, encrypted, or obfuscated content.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Create service tests
Generate focused tests for Java services with repository, client, or cache dependencies.
Improve branch coverage
Add tests for uncovered branches, boundary inputs, and exception cases in business logic.
Standardize team testing
Apply a consistent JUnit and Mockito structure across classes and modules.
Try These Prompts
Generate JUnit 5 tests for this Java class. Follow the existing package, naming, and assertion style.
Review this service and create tests for success, validation, and dependency failure paths using Mockito.
Use the coverage report and source class to add tests for uncovered branches and boundary cases.
Analyze this module, identify hard-to-mock dependencies, suggest small refactors, then create focused unit tests.
Best Practices
- Provide the source class, related interfaces, and one existing test for style reference.
- Ask for behavior-focused assertions instead of broad object comparisons.
- Keep each test independent, fast, and clear about the scenario under test.
Avoid
- Do not ask for tests without providing the source class or dependency contracts.
- Do not overuse Spring context tests when simple Mockito tests are enough.
- Do not assert private implementation details that make tests fragile.
