Java Change With Tests

What This Skill Does

The Java Change With Tests skill, developed by tanerilyazov, provides a structured and safety-conscious workflow for implementing modifications in Java repositories. Designed specifically for OpenClaw AI agents, this skill enforces a rigorous TDD-like (Test-Driven Development) methodology. It ensures that every code change—whether it is a new feature, a code refactor, or a bug fix—is backed by verified test coverage. By following a standardized lifecycle of repo mapping, planning, implementation, verification, and PR-ready summary generation, it minimizes the risk of introducing regressions into complex Java codebases.

Installation

To install this skill, use the OpenClaw command-line interface within your environment: clawhub install openclaw/skills/skills/tanerilyazov/java-change-with-tests

Use Cases

This skill is ideal for enterprise-grade Java projects where stability is paramount. Use it when:

• Implementing new business logic in a multi-module Maven or Gradle project.
• Refactoring legacy code that lacks existing test documentation.
• Resolving critical production bugs that require verified patches.
• Ensuring strict adherence to project-specific testing conventions.

Example Prompts

1. "I need to add a new authentication filter to our core-api module. Use the Java Change With Tests skill to implement this, ensure you add unit tests for the filter, and verify with mvn test."
2. "Refactor the OrderService class to improve performance; please use the Java Change With Tests skill to ensure current functionality remains intact via integration tests."
3. "Fix the NullPointerException in the PaymentProcessor. Please plan the change, implement it, and run targeted tests to verify the fix."

Tips & Limitations

To maximize the effectiveness of this skill, always provide clear acceptance criteria. If your repository uses a non-standard build tool, explicitly define that in your request. While the skill encourages fast unit tests, do not hesitate to ask for integration tests if your change interacts with databases or external APIs. Note that this skill assumes the agent has appropriate file-read and write permissions for the target repository. Always review the output PR summary before submitting to ensure it meets your team's internal documentation standards.
