Unit Testing

Automate version bumping, changelog generation, and release preparation. Creates release PR that triggers GitHub Actions workflow for building, testing, and publishing.

Comprehensive testing strategies for Guts including unit tests, integration tests, property-based testing, and fuzzing

Enforces quality verification gates with four-step validation (tests pass, build succeeds, checklist complete, no blockers) before task completion, PR creation, or status updates. Auto-activates when user says "done", "complete", "finished", "ready to merge", or runs /ccpm:verify or /ccpm:done commands. Provides systematic verification workflow that prevents false completion claims and ensures production readiness. Blocks external system writes (Jira, Slack) until evidence collected. Integrates with external-system-safety for confirmation workflow. When verification fails, suggests /ccpm:verify to debug issues systematically.

Comprehensive quality validation for TypeScript/JavaScript projects - runs TypeScript checks, tests, coverage analysis, build validation, and linting with structured JSON results

Pattern for automated testing with GitHub issue creation and Claude Code auto-fixing. Creates Test → Fail → Issue → Fix → Repeat cycle until tests pass.

This skill should be used when performing fast iterative kernel debugging, running time-bound kernel sessions to detect specific log signals or test kernel behavior. Use for rapid feedback cycles during kernel development, boot sequence analysis, or feature verification.

Testing workflow patterns and quality standards. Activate when working with tests, test files, test directories, code quality tools, coverage reports, or testing tasks. Includes zero-warnings policy, targeted testing during development, mocking patterns, and best practices across languages.

Performance and load testing with k6 and Locust. Use when validating system performance under load, stress testing, identifying bottlenecks, or establishing performance baselines.

Create comprehensive MATLAB unit tests using the MATLAB Testing Framework. Use when generating test files, test cases, unit tests, test suites, or when the user requests testing for MATLAB code, functions, or classes.

Master skill for intelligent test case generation. Identifies technology stack and delegates to specialized testing sub-skills for creating high-quality integration and API tests.

Your approach to handling packages testing. Use this skill when working on files where packages testing comes into play.

Write robust, maintainable tests for scientific Python packages using pytest best practices following Scientific Python community guidelines

Interact with iOS simulators and verify app behavior using xcobra

Validate Jupyter notebooks (.ipynb files) for production readiness. Checks smart links consistency, layout structure, transition cells with action cards, numbered part flow, cell ordering, and overall quality. Use when validating notebooks, checking notebook structure, testing smart links, verifying action cards, or preparing notebooks for production deployment. Keywords include ipynb validation, notebook structure, smart links, action cards, transitions, part flow, production ready.

Lint and test shell scripts using ShellCheck and BATS. Use when checking bash/sh scripts for errors, writing shell script tests, fixing ShellCheck warnings, setting up CI/CD for shell scripts, or improving bash code quality.

QA Automation Engineer skill. Use this to write or refactor unit tests. Ensures tests follow the project's xUnit, FluentAssertions, and Moq standards.

Reviews pytest test code for async patterns, fixtures, parametrize, and mocking. Use when reviewing test_*.py files, checking async test functions, fixture usage, or mock patterns.

Automated test fixture generation for Vigil Guard's 8-file test suite. Use for TDD workflow, malicious/benign payload creation, 3-branch detection testing, bypass scenario testing, and maintaining test coverage.

Backup, restore, and validate golden datasets for AI/ML systems - ensuring test data integrity and preventing catastrophic data loss

Ignore file management for .gitignore, .dockerignore, and .specstory directories. Includes synchronization, alphabetical ordering, organization, best practices, and testing guidelines. Activate when working with .gitignore, .dockerignore, .specstory files, or managing version control and Docker build context.
