- Implemented tests covering the `init()`, `bindEvents()`, `loadLibrary()`, and `fixSEO()` methods in `frontend/public/js/media.js`. - Mocked DOM APIs and injected global WP and Gemini references to handle isolated unit testing using jsdom. - Updated `media.js` with a conditional `module.exports` block to support Jest execution without breaking browser usage. - Tests verify initialization, edge cases (missing DOM elements), network failures, UI states, and event listeners.

🎯 What: The
frontend/public/js/media.jslogic was entirely untested due to reliance on browser-native UI event bindings, DOM manipulations, and external API globals (window.wpAPI,window.gemini). This PR introduces a Jest configuration usingjsdomto emulate the environment and implements a robust test suite that covers the media library initialization, file uploading UI bindings, network error handling during content loads, and interactive AI functions likefixSEO.📊 Coverage:
init()- Validation that core bootstrap routines (bindEvents,loadLibrary) trigger as expected.bindEvents()- Verifies that drag-and-drop actions correctly trigger file handlers without breaking execution if the DOM elements are missing.loadLibrary()- Evaluates successful and failed network fetches, ensuring the syncing UI correctly populates or gracefully renders local fallbacks. Confirms CSS class styling handles SEO-status edge cases.fixSEO()- Verifies state changes when triggering AI background jobs and handles scenarios where the returned Gemini AI prompt parsing fails.✨ Result: Test coverage for
media.jsincreased significantly. We successfully caught potential DOM referencing bugs (e.g., verifyingchildrenandinnerHTMLare only addressed when elements truly exist) and the module can now be safely extended or refactored with an immediate safety net.PR created automatically by Jules for task 13088429904242443268 started by @instituto-ops
