From 51c5baa164cac260f2358edd670ff2c1c3de8ee7 Mon Sep 17 00:00:00 2001 From: Molecule AI Fullstack Engineer Date: Mon, 18 May 2026 03:35:55 +0000 Subject: [PATCH] test(handlers): add sqlmock suite for BroadcastHandler MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit POST /workspaces/:id/broadcast was completely untested despite being a real handler with auth, DB queries, error recovery, and WS fan-out. Adds 10 focused scenarios: - Happy path: two recipients get BROADCAST_MESSAGE + activity rows - Invalid workspace ID → 400 - Workspace not found (sql.ErrNoRows) → 404 - broadcast_enabled=false → 403 with error=broadcast_disabled - No other workspaces → 200 delivered=0, no broadcasts - Recipient activity_log insert fails → handler skips and continues - Sender activity_log insert fails → still returns 200 - Missing message key → 400 - Missing body → 400 - broadcastTruncate edge cases (unicode, boundary, empty) Also: extractAgentText had no test block in the canvas suite — adds 11 cases covering top-level parts, artifacts, status.message, priority order, string identity, malformed input, and multi-part join. While here, refactors BroadcastHandler.broadcaster field from the concrete *events.Broadcaster type to the events.EventEmitter interface so the constructor accepts test doubles without a concrete dependency. The concrete type still satisfies the interface.
