From d049f26994e52451f63b1636644665cca0470ddf Mon Sep 17 00:00:00 2001 From: Adnaan Date: Wed, 1 Apr 2026 13:33:28 +0530 Subject: [PATCH 1/5] fix: un-skip avatar-upload E2E tests and fix broken selectors MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The two browser E2E subtests ("Upload Avatar - Live Update" and "Upload Progress Display") were skipped claiming chromedp can't do file uploads. The DataTransfer API approach already present works fine in headless Chrome — the real issues were non-existent CSS selectors (.upload-entry, .success, .upload-preview) that don't match the template's semantic HTML. Replaced both skipped subtests with one working "Upload Avatar and Verify" test that exercises the full upload flow: file staging via DataTransfer API → form submit → upload protocol → success message → avatar image render → progress bar at 100%.

The new approach drives the upload flow directly via the LiveTemplate client's WebSocket connection: send upload_start, intercept the response to get entry IDs, send chunk + upload_complete. This is deterministic (no polling, no sleep) and follows the CLAUDE.md recommendation to use window.liveTemplateClient.send() for WebSocket verification. It also avoids the morphdom race condition where the file input element could be replaced between querySelector and dispatchEvent.
