From 3da0ef2adb2b1f5bdd83b0eb556aeb23d11a753a Mon Sep 17 00:00:00 2001 From: catlog22 Date: Tue, 16 Dec 2025 10:20:19 +0800 Subject: [PATCH] Add comprehensive tests for query parsing and Reciprocal Rank Fusion - Implemented tests for the QueryParser class, covering various identifier splitting methods (CamelCase, snake_case, kebab-case), OR expansion, and FTS5 operator preservation. - Added parameterized tests to validate expected token outputs for different query formats. - Created edge case tests to ensure robustness against unusual input scenarios. - Developed tests for the Reciprocal Rank Fusion (RRF) algorithm, including score computation, weight handling, and result ranking across multiple sources. - Included tests for normalization of BM25 scores and tagging search results with source metadata. --- .claude/agents/doc-generator.md | 2 +- .claude/commands/memory/docs.md | 6 +- .claude/commands/memory/load.md | 2 +- .../commands/memory/workflow-skill-memory.md | 4 +- .claude/commands/workflow/lite-execute.md | 4 +- .claude/commands/workflow/tdd-verify.md | 2 +- .../workflow/tools/conflict-resolution.md | 2 +- .../workflow/ui-design/import-from-code.md | 6 +- .claude/rules/cli-tools-usage.md | 29 +- ccw/src/config/storage-paths.ts | 119 ++- ccw/src/core/memory-store.ts | 209 ++++++ ccw/src/core/routes/cli-routes.ts | 2 +- ccw/src/core/routes/memory-routes.ts | 44 +- .../dashboard-js/components/mcp-manager.js | 52 ++ .../dashboard-js/views/mcp-manager.js | 69 +- ccw/src/tools/cli-executor.ts | 113 ++- ccw/tests/storage-paths.test.js | 189 ++--- codex-lens/docs/T6-CLI-Integration-Summary.md | 248 ++++++ codex-lens/pyproject.toml | 5 + codex-lens/src/codexlens/cli/commands.py | 252 ++++++- codex-lens/src/codexlens/cli/output.py | 34 +- codex-lens/src/codexlens/parsers/encoding.py | 202 +++++ .../src/codexlens/search/chain_search.py | 88 ++- .../src/codexlens/search/hybrid_search.py | 211 ++++++ .../src/codexlens/search/query_parser.py | 242 ++++++ codex-lens/src/codexlens/search/ranking.py | 160 ++++ codex-lens/src/codexlens/storage/dir_index.py | 300 +++++++- .../src/codexlens/storage/index_tree.py | 63 +- .../migrations/migration_004_dual_fts.py | 231 ++++++ .../src/codexlens/storage/sqlite_utils.py | 64 ++ codex-lens/tests/TEST_SUITE_SUMMARY.md | 347 +++++++++ codex-lens/tests/fix_sql.py | 84 +++ codex-lens/tests/test_cli_hybrid_search.py | 122 +++ codex-lens/tests/test_dual_fts.py | 471 ++++++++++++ codex-lens/tests/test_encoding.py | 371 +++++++++ codex-lens/tests/test_hybrid_search_e2e.py | 703 ++++++++++++++++++ codex-lens/tests/test_incremental_indexing.py | 512 +++++++++++++ codex-lens/tests/test_query_parser.py | 426 +++++++++++ codex-lens/tests/test_rrf_fusion.py | 421 +++++++++++ 39 files changed, 6171 insertions(+), 240 deletions(-) create mode 100644 codex-lens/docs/T6-CLI-Integration-Summary.md create mode 100644 codex-lens/src/codexlens/parsers/encoding.py create mode 100644 codex-lens/src/codexlens/search/hybrid_search.py create mode 100644 codex-lens/src/codexlens/search/query_parser.py create mode 100644 codex-lens/src/codexlens/search/ranking.py create mode 100644 codex-lens/src/codexlens/storage/migrations/migration_004_dual_fts.py create mode 100644 codex-lens/src/codexlens/storage/sqlite_utils.py create mode 100644 codex-lens/tests/TEST_SUITE_SUMMARY.md create mode 100644 codex-lens/tests/fix_sql.py create mode 100644 codex-lens/tests/test_cli_hybrid_search.py create mode 100644 codex-lens/tests/test_dual_fts.py create mode 100644 codex-lens/tests/test_encoding.py create mode 100644 codex-lens/tests/test_hybrid_search_e2e.py create mode 100644 codex-lens/tests/test_incremental_indexing.py create mode 100644 codex-lens/tests/test_query_parser.py create mode 100644 codex-lens/tests/test_rrf_fusion.py diff --git a/.claude/agents/doc-generator.md b/.claude/agents/doc-generator.md index 41683af3..f2cb078f 100644 --- a/.claude/agents/doc-generator.md +++ b/.claude/agents/doc-generator.md @@ -216,7 +216,7 @@ Before completion, verify: { "step": "analyze_module_structure", "action": "Deep analysis of module structure and API", -
