Can I use this for both Chrome and Firefox testing?

Yes, the workflow allows you to specify the target build and browser to ensure cross-platform compatibility for the extension.

Does this skill help with Playwright Trace Viewer?

Yes, it prioritizes gathering and analyzing Playwright traces, screenshots, and videos to provide a root cause based on evidence rather than estimation.

How does this skill handle expired YouTube live stream URLs?

Instead of using hardcoded links, the skill searches for active live streams using specific query parameters, ensuring the test always has a valid target.

What is the primary method for reducing test flakiness?

The skill avoids 'sleep' or 'timeout' functions, instead favoring explicit UI state waits like 'toBeVisible' and using stable ARIA roles or text-based selectors.

Security & Testing

Debugs and fixes Playwright end-to-end tests for browser extensions while minimizing flakiness in dynamic environments.

The Playwright E2E Debugger skill is designed to streamline the reproduction, debugging, and fixing of test failures within the Youtube-Live-Chat-Fullscreen extension project. It provides a robust workflow for handling the non-deterministic nature of YouTube Live content by dynamically searching for active streams rather than relying on hardcoded URLs. By enforcing best practices—such as using stable selectors, explicit UI state waiting, and capturing trace artifacts—this skill helps developers maintain a reliable CI/CD pipeline and resolve complex browser automation issues efficiently.
