testing▌

Delivers changes incrementally to manage large features effectively.

50+ production-tested Playwright patterns for E2E, API, component, visual, accessibility, and security testing. \n \n Covers 10 golden rules including resilient locator selection ( getByRole() first), web-first assertions with auto-retry, fixture-based test isolation, and CI/CD best practices across GitHub Actions, GitLab, CircleCI, Azure, and Jenkins \n Includes framework-specific recipes for React, Next.js, Vue, Angular, and migration guides from Cypress and Selenium with TypeScript and JavaSc

Interactive QA session where users report bugs conversationally, and the agent files GitHub issues while exploring the codebase for context.

End-to-end testing focused on real user behavior, minimal mocking, and avoiding component unit tests. \n \n Prioritizes E2E tests over unit tests; reserves unit tests for pure functions only \n Emphasizes accessible selectors (role-based, label-based) over CSS selectors and test IDs in E2E tests \n Recommends writing E2E tests instead of heavily mocked unit tests; suggests 3+ mocks as a signal to switch approaches \n Includes rules for test structure, selector strategy, and when to apply each te

Detect the project type, generate the right Vitest configuration, and produce working test infrastructure. Not a reference card — this skill creates files.

Generate Playwright tests from scenarios using interactive browser exploration and validation. \n \n Guides you through step-by-step test creation: scenario review, browser exploration, element inspection, interaction validation, and final test generation \n Integrates with Playwright MCP tools to inspect page elements, capture selectors, and validate interactions before writing test code \n Generates TypeScript tests using @playwright/test framework and automatically saves them to the tests dir

Conduct effective usability testing using frameworks from 11 product leaders. \n \n Choose the right test fidelity: fake doors and Wizard of Oz tests for concept validation, prototypes for design feedback, production testing for optimization \n Small sample sizes (10 random users) reveal core friction points; direct observation of user behavior uncovers needs that surveys miss \n Test multiple design options simultaneously to measure relative performance, not single designs in isolation \n Bring

Generates unit, widget, integration, and plugin tests for Flutter applications with architectural awareness. \n \n Analyzes target code to determine appropriate test type (unit for logic, widget for UI, integration for end-to-end, plugin for native code) \n Provides decision tree and step-by-step implementation patterns for each test category, including fake/mock setup and assertion strategies \n Includes ready-to-use code templates for ViewModels, Repositories, widgets, and full app flows with

Write and review React Native component tests using Testing Library v13 and v14. \n \n Covers render patterns, screen queries (getBy/getAllBy/queryBy/findBy variants), Jest matchers, userEvent interactions, fireEvent, and async patterns with version-specific behavior \n Automatically detects your project's RNTL version (v13 for React 18, v14 for React 19+) and applies correct API signatures and sync/async rules \n Provides query priority guidance (getByRole first), interaction best practices (us
