From fe517158a0215815845352571a89e2c09b4d4286 Mon Sep 17 00:00:00 2001 From: StepFun Date: Sat, 25 Apr 2026 20:58:00 -0400 Subject: [PATCH] feat: add test documentation generator (#88) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Introduce scripts/test_documentation_generator.py: scans test files, adds module docstrings (explaining what is tested) and function docstrings (explaining verification purpose) without altering logic. - Applies documentation to 11 previously-undocumented test files: * tests/test_ci_config.py — added module-level docstring * tests/test_dedup.py — 30 function docstrings * tests/test_knowledge_gap_identifier.py — 10 function docstrings * tests/test_perf_bottleneck_finder.py — 25 function docstrings * tests/test_quality_gate.py — 14 function docstrings * scripts/test_diff_analyzer.py — 10 function docstrings * scripts/test_gitea_issue_parser.py — 6 function docstrings * scripts/test_harvest_prompt_comprehensive.py — 5 function docstrings * scripts/test_improvement_proposals.py — 2 function docstrings * scripts/test_knowledge_staleness.py — 8 function docstrings * scripts/test_session_pair_harvester.py — 5 function docstrings - Idempotent: re-running detects all 19 test files as up-to-date. - Processes up to 25 files per run (meets 20+ capacity requirement).
