From 2f01f0f3153f1eee6459df63b3af8b631eaef802 Mon Sep 17 00:00:00 2001 From: Inkman007 Date: Fri, 24 Apr 2026 15:49:09 +0000 Subject: [PATCH] feat(frontend): fix appearance.test.tsx and add theme e2e tests appearance.test.tsx: - Remove broken ReactNode.useState reference (ReactNode is a type, not a namespace with a useState method) - Wire ThemeAppearanceSection directly to useTheme() from ThemeContext so preference state and setTheme come from the real context - Add test for active-state update when preference changes e2e/theme-persistence.spec.ts: - Verify default (no stored value) resolves to a valid theme - Verify dark/light/system preferences persist across page reload - Verify NoFlashScript applies data-theme before React hydrates - Verify color-scheme style matches resolved theme - Verify ThemeSelect dropdown (settings page) updates storage + attribute Closes issue #24 (dark/light/system theme). --- frontend/e2e/theme-persistence.spec.ts | 137 ++++++++++++++++++ frontend/src/app/settings/appearance.test.tsx | 52 +++---- 2 files changed, 156 insertions(+), 33 deletions(-) create mode 100644 frontend/e2e/theme-persistence.spec.ts diff --git a/frontend/e2e/theme-persistence.spec.ts b/frontend/e2e/theme-persistence.spec.ts new file mode 100644 index 00000000..74163959 --- /dev/null +++ b/frontend/e2e/theme-persistence.spec.ts @@ -0,0 +1,137 @@ +import { test, expect } from '@playwright/test';
