SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill fills gaps in model and developer knowledge about Playwright versions 1.50–1.59 so generated tests, configuration, and tooling do not rely on removed selectors, deprecated options, or APIs introduced after the model cutoff.

Core Features & Use Cases

  • Screencast API: recording, overlays, chapters, and real-time frame streaming for visual test artifacts.
  • Browser binding and dashboard: share launched browsers via browser.bind/unbind and connect via CLI or WebSocket.
  • Test runner & agents: new test.step options, TestStepInfo, per-project workers, failOnFlakyTests, test agents (planner/generator/healer).
  • Page/context APIs and storage: storageState with IndexedDB, context.setStorageState, async disposables, console/page diagnostics.
  • Breaking changes & compatibility: concise removal notices for legacy selectors, launch options, and platform support, with migration guidance.
  • Use Case: Scan a test suite or codegen workflow to ensure Playwright tests use the correct new APIs (for example, migrate from legacy selectors and adopt screencast or browser.bind features).

Quick Start

Load the playwright-knowledge-patch and run the knowledge-patch setup to scan your project and apply Playwright 1.50–1.59 guidance.
