p3c-unit-testing

What problem does it solve?

This skill defines standardized unit testing guidelines aligned with AIR (Automatic, Independent, Repeatable) principles to improve reliability and maintainability of Java codebases.

Core Features & Use Cases

• AIR compliance: Mandates automated, isolated, and repeatable unit tests.
• Guidance for scope: Clarifies when to test at class vs method level and how to structure test suites.
• Practical use case: When adding a new service, design tests that verify core logic with mocks for external dependencies and ensure tests live under src/test/java.

Quick Start

Create a unit test suite for a Java class following AIR: place tests under src/test/java, use mocks for external services, and run tests automatically with no user intervention.
