From abd1d341daf0c659c80fdf7f5695d45995b8770c Mon Sep 17 00:00:00 2001 From: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> Date: Tue, 1 Jul 2025 22:07:13 +0000 Subject: [PATCH] Address GitHub review feedback: add URL validation, helper functions, and edge case tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add _validate_url() helper function with proper URL validation using urllib.parse - Add _construct_embeddings_url() helper function to refactor URL construction logic - Add comprehensive error handling with ValueError for invalid URLs - Fix test mocking to use correct chromadb import path - Add edge case tests for invalid URLs with pytest markers - Organize tests with @pytest.mark.url_configuration and @pytest.mark.error_handling - Remove unused imports (pytest, MagicMock) to fix lint issues This addresses all suggestions from joaomdmoura's AI review while maintaining backward compatibility.
