From 10e60d66cbe8651cdfa4c80418299fd672bf1e17 Mon Sep 17 00:00:00 2001 From: Molecule AI Core-FE Date: Sun, 10 May 2026 04:26:11 +0000 Subject: [PATCH] test(canvas): add pure-function tests for deriveWsBaseUrl, statusDotClass, and readThemeCookie MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - ws-url.test.ts: deriveWsBaseUrl — all 4 priority paths tested: NEXT_PUBLIC_WS_URL (strips /ws suffix), NEXT_PUBLIC_PLATFORM_URL (http→ws, https→wss), window.location (https→wss, http→ws), precedence over lower-priority paths. - statusDotClass.test.ts: all STATUS_CONFIG entries (online/offline/paused/ degraded/failed/provisioning/not_configured), fallback to bg-zinc-500, case-sensitivity, purity. - theme-cookie.test.ts: readThemeCookie — valid values (light/dark/system), undefined/empty fallback, invalid value handling, case-sensitivity, purity.
