Playwright end-to-end testing best practices for web applications, covering test design, locator strategies, and assertion patterns.
Vitest testing framework: Vite-powered tests, Jest-compatible API, mocking, snapshots, coverage, browser mode, and TypeScript support.
Run lint, build, and E2E tests in sequence. Use when the user wants to validate their code, run tests, or check if everything works before committing.
Write pytest unit tests for Python code changes. Use when adding tests for new or modified Python code in projects that use pytest.
Implement minimal code to make failing tests pass (GREEN phase). Use when you have a failing test and need to write just enough code to make it pass.
Measure quality effectively with actionable metrics. Use when establishing quality dashboards, defining KPIs, or evaluating test effectiveness.
Safely refactor code while keeping tests green (REFACTOR phase). Use when tests pass and you want to improve code structure without changing behavior.
Deployment workflows, pre-deploy validation, and smoke testing patterns. Use when deploying to staging or production, running smoke tests, or validating deployments.
O(log n) sublinear coverage gap detection with risk-weighted analysis and intelligent test prioritization.
Compile a FRINK evidence pack after implementation and testing. Use to capture diffs, test results, logs, and reproduction steps so reviewers can verify changes.
Use when feature flag tests fail, flags need updating, understanding @gate pragmas, debugging channel-specific test failures, or adding new flags to React.
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.
Test-Driven Development specifically for Laravel applications using Pest PHP. Use when implementing any Laravel feature or bugfix - write the test first, watch it fail, write minimal code to pass.

CLI modernization and hooks system enhancement for claude-flow v3. Implements interactive prompts, command decomposition, enhanced hooks integration, and intelligent workflow automation.
Run what-if scenarios to explore outcomes and test hypotheses. Use when evaluating alternatives, stress-testing designs, exploring edge cases, or predicting system behavior under different conditions.
A test skill that responds to the magic word "flarglebargle" with a compliment. Use for testing skill activation and trigger functionality.
Statistical analysis toolkit. Hypothesis tests (t-test, ANOVA, chi-square), regression, correlation, Bayesian stats, power analysis, assumption checks, APA reporting, for academic research.
