Testing & QA

Comprehensive Cloudflare platform skill covering Workers, Pages, storage (KV, D1, R2), AI (Workers AI, Vectorize, Agents SDK), networking (Tunnel, Spectrum), security (WAF, DDoS), and infrastructure-as-code (Terraform, Pulumi). Use for any Cloudflare development task.

Use when Codex is building or iterating on a web game (HTML/JS) and needs a reliable development + testing loop: implement small changes, run a Playwright-based test script with short input bursts and intentional pauses, inspect screenshots/text, and review console errors with render_game_to_text.

Build reliable, fast, and maintainable end-to-end test suites that provide confidence to ship code quickly and catch regressions before users do.

Plan and build comprehensive Playwright E2E test suites with Page Object Model, authentication state persistence, custom fixtures, visual regression, and CI integration. Uses interview-driven planning to clarify critical user flows, auth strategy, test data approach, and parallelization before writing any tests.

Scaffold, write, debug, and enhance enterprise-grade Playwright E2E tests in Java using Page Object Model, JUnit 5, Allure reporting, and parallel execution.

Use when the task requires automating a real browser from the terminal (navigation, form filling, snapshots, screenshots, data extraction, UI-flow debugging) via `playwright-cli` or the bundled wrapper script.

Auto-detect testing framework and run relevant tests. Identifies Jest, Vitest, Playwright, Cypress, pytest, Go test, and others. Can run all tests, specific file tests, or generate basic tests for new code. Usage - /test-detect, /test-detect src/auth/login.ts, /test-detect generate src/utils.ts

Jest testing patterns, factory functions, mocking strategies, and TDD workflow. Use when writing unit tests, creating test factories, or following TDD red-green-refactor cycle.

Complete browser automation with Playwright. Auto-detects dev servers, writes clean test scripts to /tmp. Test pages, fill forms, take screenshots, check responsive design, validate UX, test login flows, check links, automate any browser task. Use when user wants to test websites, automate browser interactions, validate web functionality, or perform any browser-based testing.

Web application testing principles. E2E, Playwright, deep audit strategies.

Prepares codebases for security review using Trail of Bits' checklist. Helps set review goals, runs static analysis tools, increases test coverage, removes dead code, ensures accessibility, and generates documentation (flowcharts, user stories, inline comments).

Graph-informed mutation testing triage. Parses codebases with Trailmark, runs mutation testing and necessist, then uses survived mutants, unnecessary test statements, and call graph data to identify false positives, missing test coverage, and fuzzing targets. Use when triaging survived mutants, analyzing mutation testing results, identifying test gaps, finding fuzzing targets from weak tests, running mutation frameworks (including circomvent and cairo-mutants), or using necessist.

在编写新功能、修复 Bug 或重构代码时使用此技能。强制执行测试驱动开发 (TDD)，包括单元测试、集成测试和端到端 (E2E) 测试，确保覆盖率达到 80% 以上。

MASTER Vue.js application testing with strict enforcement of verification protocols. Systematically test functionality with Playwright, validate bug fixes, verify features work, and enforce zero-tolerance policies for false success claims. MANDATORY testing with visual evidence before any deployment or functionality claims.

Write Minitest tests for Ruby and Rails applications. Use when creating test files, writing test cases, or testing new features. Not for RSpec — use rspec-coder instead. Covers both traditional and spec styles, fixtures, mocking, and Rails integration testing patterns.

Use proactively when refactoring Ruby on Rails code. Applies Rails conventions, Sandi Metz rules, and idiomatic Ruby patterns while maintaining test coverage.
