Testing & QA

Build and configure Laravel 10+ applications with Eloquent models, Sanctum authentication, Horizon queues, RESTful APIs, and Livewire components.

Generates Spring Boot 3.x configurations, REST controllers, Spring Security 6 authentication flows, Spring Data JPA repositories, and reactive WebFlux endpoints for building microservices and reactive Java applications.

Interpret n8n validation errors and warnings, guide iterative fixes, and explain validation profiles, error types, and auto-sanitization.

Control browsers via a CLI tool that runs sandboxed JavaScript scripts for automation, testing, and data extraction.

Create new skills, modify and improve existing skills, and measure skill performance through iterative evaluation and benchmarking.

Generates Jest unit and integration tests in JavaScript or TypeScript, covering mocking, snapshots, async testing, and React component testing.

Build reliable, fault-tolerant Python applications with DBOS durable workflows, steps, queues, and communication patterns.

Validates observable behavior of apps, CLIs, APIs, and generated artifacts against a prewritten contract without inspecting source code.

Provides a repeatable, auditable workflow for large coding tasks by initializing repo-local task artifacts, installing subagent templates, and running a spec-freeze → build → evidence → verify → fix loop with fresh-session verification.

Run GitHub Actions workflows locally with act, including installation, configuration, event payloads, secrets, and debugging.

Tests local web applications by writing native Python Playwright scripts, with helpers for server lifecycle management, DOM inspection, and screenshot capture.

根据用户指定的数量和主题，生成适合前端JavaScript面试的手写代码题目，涵盖算法、DOM、异步编程、ES6+等核心领域。

编写评估FastText文本分类模型的Python函数，计算accuracy、F1、recall和precision指标，并处理特定格式的标签文本分割。

Creates custom ESLint rules using the ESLint RuleTester API and AST Explorer patterns, generating rule implementations with auto-fix suggestions based on estree node types and scope analysis.

Automates end-to-end QA: starts the app, exercises screens and API endpoints, verifies functionality and design quality, runs domain analysis, and fixes issues found.

Maps external dependencies and I/O boundaries, generates chaos tests for failure modes like timeouts and connection errors, runs them, and reports resilience gaps with fixes.

Runs a comprehensive QA audit on Unity, Unreal, Godot, or web game projects, covering null references, missing assets, scene transitions, physics, input, save/load, localization, audio, and platform certification.

Runs a comprehensive mobile QA audit covering permissions, deep links, push notifications, offline mode, background/foreground transitions, memory leaks, network conditions, accessibility, and platform edge cases for Flutter, React Native, and native iOS/Android apps.

Walks a running app across routes, states, and interactions to find real bugs, then root-causes, fixes, adds regression tests, and verifies each fix before committing.

Runs a hypothesis-driven debugging workflow that reproduces failures, forms discriminating tests, proves root cause via toggle, and delivers a fix, regression test, and postmortem.

Generates comprehensive unit tests with edge cases, error paths, and boundary values. Auto-detects the test framework, scans for untested functions, adopts existing conventions, runs tests, and self-heals failures in up to 3 iterations while measuring coverage.

Analyzes test coverage across unit, integration, E2E, load, visual regression, contract, and accessibility dimensions, scores health, and routes remediation to specific testing sub-skills.

Launches a Flutter app on a simulator or emulator, generates and runs exhaustive integration tests covering every screen, button, form, and user flow, then self-heals failures.

Writes Jest unit tests for Lightning Web Components using @salesforce/sfdx-lwc-jest, covering wire adapter mocks, imperative Apex mocking, and async rerender handling.

Defines a test strategy for Salesforce Flow, combining declarative Flow Tests, debug runs, path matrices, test data, and boundary tests for Apex, LWC, and external services.

Impersonate a user in Apex tests with System.runAs to verify sharing, profile, and permission-set behavior, and to work around mixed-DML errors in test setup.

Writes and debugs Apex test classes for Salesforce CPQ, covering quote setup, price rule execution via ServiceRouter, contracting, and order generation.

Runs a persistent verification-and-fix loop, executing existing test suites and browser/desktop checks until the requested surface is verified or a real blocker remains.

Build and run custom fuzzers with LibAFL, a modular Rust fuzzing library, including drop-in libFuzzer replacement and custom component configuration.

Guides setting up and using Atheris for coverage-guided fuzzing of Python code and C extensions, including Docker setup, harness writing, and corpus management.

Strengthen interfaces against edge cases, errors, internationalization issues, and real-world usage scenarios that break idealized designs.

Systematically explores a web application, finds issues, and produces a report with reproduction evidence for each finding.

Generates unit tests for code changed in the current branch by comparing against origin/main and following existing test conventions.

Guides test-first development with vertical slices, writing one behavior test at a time and refactoring only when green.

Runs and writes tests, verifies behavior, and orchestrates two-pass TDD across scoped modes, blocking on quality gates and never editing production code.

Derives a comprehensive test plan and writes unit, integration, and end-to-end test cases from user stories and acceptance criteria, flagging issues in prior artifacts and declaring UAT readiness.
