Does it cover visual regression testing?

Absolutely. The skill includes specific patterns for visual testing to catch unintended UI changes that traditional functional tests might miss.

What frameworks are supported by this skill?

This skill primarily focuses on best practices and patterns for Playwright and Cypress, the leading modern web testing frameworks.

Can I use this for mobile web testing?

Yes, it includes patterns for cross-browser testing and mobile device emulation using Playwright’s device descriptors and Cypress viewport configurations.

How does it handle external API dependencies?

It provides detailed patterns for network mocking and request interception to isolate frontend tests from backend instability and ensure consistent test data.

How does this skill help with flaky tests?

It provides advanced waiting strategies and deterministic testing patterns that replace brittle, time-based waits with condition-based assertions and network state monitoring.

セキュリティとテスト

Implements reliable, maintainable end-to-end testing suites using Playwright and Cypress to ensure high-quality web applications.

概要

This skill provides advanced patterns and best practices for building robust end-to-end (E2E) testing suites that catch regressions and improve deployment confidence. It covers industry-standard frameworks like Playwright and Cypress, offering guidance on implementing the Page Object Model, managing test data through fixtures, and handling asynchronous actions with smart waiting strategies. Whether you're debugging flaky tests, setting up CI/CD pipelines, or implementing visual regression testing, this skill ensures your test suites are fast, deterministic, and scalable.
