About

Attribute Scanner helps QA engineers and developers quickly identify elements with or without test automation attributes on any webpage.

 Perfect for:
    • Cypress testing (data-cy)
    • Playwright/Testing Library (data-testid)
    • Custom QA frameworks (data-qa, data-test, etc.)

Features:
✅ Find elements WITH an attribute - Highlights all elements that have your specified attribute with a green outline
❌ Find elements MISSING an attribute - Highlights interactive elements (buttons, links, inputs, etc.) that are missing test attributes with a red outline - perfect for finding gaps in test coverage

🎯 Customizable - Works with any attribute name: data-cy, data-testid, data-qa, or your own custom attributes
 🧹 Clean up - Clear all highlights with one click

How to use:
 1. Click the extension icon
 2. Enter the attribute name (default: data-cy)
 3. Choose to scan for elements WITH or MISSING the attribute
 4. Click "Scan Page" to highlight matching elements

Privacy-focused: Minimal permissions required. Only accesses the current tab when you click scan. No data collection.
