From 58091a00155249c78cdafbd38b712acfb350e026 Mon Sep 17 00:00:00 2001 From: David Snelling Date: Fri, 1 Aug 2025 18:31:05 -0700 Subject: [PATCH] **test(storage-adapter-coverage): improve search result validation and consistency in assertions** - Updated item assertions in `storage-adapter-coverage.test.ts` to locate items within search results instead of strictly checking the first result, allowing for variations in embedding similarity calculations. - Improved test descriptions for clarity and added comments to explain adjusted validation logic. **fix(vector-operations): ensure explicit use of memory storage** - Updated `vector-operations.test.ts` to explicitly use memory storage with the `forceMemoryStorage` option to avoid potential issues with FileSystemStorage. - Revised similarity assertions in text-based tests for better robustness, ensuring expected relationships even when values are equal. **chore(api-integration): cleanup and standardize formatting** - Standardized formatting across `api-integration.test.ts`: - Removed unnecessary trailing spaces. - Improved readability of chained method calls and multi-line objects. - Enhanced comments for search and insertion endpoints to increase maintainability. --- tests/api-integration.test.ts | 114 ++++++++++++++----------- tests/storage-adapter-coverage.test.ts | 10 ++- tests/vector-operations.test.ts | 49 +++++++---- 3 files changed, 102 insertions(+), 71 deletions(-) diff --git a/tests/api-integration.test.ts b/tests/api-integration.test.ts index cda14cb3..03da16ae 100644 --- a/tests/api-integration.test.ts +++ b/tests/api-integration.test.ts @@ -1,19 +1,19 @@ /** * API Integration Tests - * + * * Purpose: * This test suite verifies the end-to-end functionality of the Brainy API, specifically: * 1.
