From 641ec489298ec844caffe43760b62f9a69adadea Mon Sep 17 00:00:00 2001 From: czlonkowski <56956555+czlonkowski@users.noreply.github.com> Date: Fri, 1 Aug 2025 08:23:34 +0200 Subject: [PATCH] fix: resolve TypeScript error in http-server-n8n-mode tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Fix Property 'json' does not exist on express mock type by adding proper interface typing - Add support for 'delete' method in findHandler function helper - Add comprehensive test coverage for security features including: - Malformed authorization headers - Valid auth token handling - DELETE endpoint behavior (returns 400 for missing session ID) - Server configuration methods - Express middleware configuration - CORS preflight handling - All tests now pass with improved coverage for security-related functionality 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- tests/unit/http-server-n8n-mode.test.ts | 207 +++++++++++++++++++++++- 1 file changed, 204 insertions(+), 3 deletions(-) diff --git a/tests/unit/http-server-n8n-mode.test.ts b/tests/unit/http-server-n8n-mode.test.ts index fffc4a8..6b3441e 100644 --- a/tests/unit/http-server-n8n-mode.test.ts +++ b/tests/unit/http-server-n8n-mode.test.ts @@ -101,8 +101,13 @@ vi.mock('express', () => { }) };
