Provides specific testing patterns and commands for the WordPress ActivityPub plugin. Includes PHPUnit and Playwright examples, debugging techniques, and references to detailed test utilities. Focuses on practical implementation rather than general testing theory.

A comprehensive and actionable quality metrics framework that effectively distinguishes meaningful metrics from vanity metrics, with excellent DORA integration and practical implementation guidance.

This skill provides detailed patterns for writing unit tests for Spring service layer classes using JUnit 5 and Mockito. It covers mocking dependencies, verifying interactions, testing exceptions, and complex workflows with practical code examples. The documentation includes setup instructions, common patterns, and troubleshooting tips for Java developers.

This skill provides concrete guidelines for writing focused tests that prioritize core user flows over edge cases. It emphasizes clear test naming, mocking external dependencies, and fast execution. The decision framework helps developers avoid over-testing during feature development while ensuring critical paths are covered.

Automates testability scoring for web apps using 10 principles with Playwright. Generates JSON and HTML reports with radar charts, integrates with CI/CD, and optionally uses Vibium for stability metrics. Provides actionable improvement priorities based on weighted scores.

This skill provides a structured framework for applying PACT principles (Proactive, Autonomous, Collaborative, Targeted) to testing strategies. It helps teams move from sequential QA to concurrent quality practices, with specific guidance on agent selection, quadrant-based testing approaches, and practical implementation steps.
