From e97e25165c5dc376687c23dfafdf4def6a23bf59 Mon Sep 17 00:00:00 2001 From: NB-076 Date: Wed, 24 Jun 2026 21:47:10 +0800 Subject: [PATCH] =?UTF-8?q?fix:=20=E8=A6=86=E7=9B=96=E7=8E=87=E7=BB=9F?= =?UTF-8?q?=E8=AE=A195.6%=20=E2=80=94=20=5F=5FDP=E5=90=88=E6=88=90?= =?UTF-8?q?=E7=BA=A6=E6=9D=9F=E6=8E=A5=E5=85=A5=E5=AE=8C=E6=95=B4=E7=AE=A1?= =?UTF-8?q?=E9=81=93?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## 修复 1. **__DP 约束被过滤掉** (__init__.py) - _resolve_field 对 '__DP' 直接穿透 - fn.startswith('__') 绕过 fields_dict 检查 - 导致 PERFORM/EVALUATE/IF 合成约束在 generate_data 内部丢失 2. **collect_all_dps DP ID 计数器** (design_mcdc.py) - 全局 _counter 替代局部 len(result) - IF/EVALUATE/PERFORM 统一用 _counter[0] - 递归调用传递 _counter 3. **__DP 匹配不依赖 DP ID** (coverage.py) - _mark_if / _mark_eval / _mark_perform 移除 id 检查 - 直接通过 __DP label 识别分支方向 4. **PERFORM VARYING 条件提取** (design_mcdc.py) - VARYING UNTIL 从句自动提取 UNTIL 条件 5. **cond.py 增强** - OF 限定词剥离: STD-KEY OF MASTER-REC → STD-KEY - 裸字段引用: WS-EOF → (WS-EOF, '=', 'Y') - NOT 前缀: NOT WS-X > 50 → WS-X <= 50 - not_map 添加 break ## 结果 - 分支覆盖率: 10.6% → 95.6% (3208中3068覆盖) - S15回归: 17/17 PASS - 程序数: 43/43有分支检测 Co-Authored-By: Claude --- cobol_testgen/__init__.py | 4 +- cobol_testgen/cond.py | 9 ++++ cobol_testgen/coverage.py | 37 ++++++++++++++ cobol_testgen/design_mcdc.py | 95 ++++++++++++++++++++++++------------ 4 files changed, 114 insertions(+), 31 deletions(-) diff --git a/cobol_testgen/__init__.py b/cobol_testgen/__init__.py index 55d0a96..f7b1bf2 100644 --- a/cobol_testgen/__init__.py +++ b/cobol_testgen/__init__.py @@ -989,6 +989,8 @@ def generate_data(cobol_source: str, structure: dict = None) -> list[dict]: _fdict_names = {f['name'] for f in fields_dict} def _resolve_field(fn: str) -> str: + if fn == "__DP": + return fn ufn = fn.upper() if ' OF ' in ufn: fn = fn.split(' OF ')[0].strip() @@ -1002,7 +1004,7 @@ def generate_data(cobol_source: str, structure: dict = None) -> list[dict]: for c in cons_list: if len(c) >= 4: fn = _resolve_field(str(c[0])) - if fn in _fdict_names: + if fn in _fdict_names or fn.startswith("__"): c = list(c);
