From de81a42873ebc92dccba41fea483033e5ac1e323 Mon Sep 17 00:00:00 2001 From: jreakin Date: Mon, 23 Mar 2026 03:48:27 -0500 Subject: [PATCH] test: add positive and negative tests for all 4 bug fixes 16 tests covering the data structures and logic underlying each fix: createKnowledgeGraph (loadServerGraph data flow): + nodes stored correctly via addNode + relationships stored correctly via addRelationship + deduplication by ID + nodeCount reflects unique count - empty graph has zero counts - relationships with non-existent nodes still stored loadServerGraph data flow: + server data reconstructs into valid KnowledgeGraph + fileContents Map built from server entries - empty server data produces empty graph - fileContents replaces (not accumulates) on reload BM25 index argument type: + Map has entries() for BM25 - KnowledgeGraph does NOT have entries() (the original bug) Highlight clearing: + clearing Set produces empty set + independent highlight sources cleared separately - clearing highlights doesn't affect node selection - toggling AI ON doesn't clear process highlights Co-Authored-By: Claude Opus 4.6 (1M context) --- gitnexus-web/test/setup.ts | 6 + gitnexus-web/test/unit/bug-fixes.test.ts | 259 +++++++++++++++++++++++ gitnexus-web/vitest.config.ts | 17 ++ 3 files changed, 282 insertions(+) create mode 100644 gitnexus-web/test/setup.ts create mode 100644 gitnexus-web/test/unit/bug-fixes.test.ts create mode 100644 gitnexus-web/vitest.config.ts diff --git a/gitnexus-web/test/setup.ts b/gitnexus-web/test/setup.ts new file mode 100644 index 0000000000..c6a2e2d532 --- /dev/null +++ b/gitnexus-web/test/setup.ts @@ -0,0 +1,6 @@ +import { beforeEach } from 'vitest';
