|
||||||
|
|
||||||
|
> 日期: 2026-06-21 | 对象: D:\cobol-java\cobol-java-v3
|
||||||
|
> 范围: COBOL 85/2002 语句类型全覆盖 × 解析/数据生成/分类 三维度
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 1. 总览
|
||||||
|
|
||||||
|
### 1.1 目标
|
||||||
|
|
||||||
|
建立 COBOL 语句级别的测试基准，验证平台对每种 COBOL 语句的：
|
||||||
|
- **解析正确性** — `cobol_testgen` 能否正确解析该语句结构
|
||||||
|
- **路径生成** — 是否能生成覆盖该语句所有分支的测试数据
|
||||||
|
- **程序分类** — HINA pipeline 能否正确判定含该语句的程序类型
|
||||||
|
- **覆盖率统计** — 静态分析能否正确统计该语句贡献的分支数
|
||||||
|
|
||||||
|
### 1.2 范围
|
||||||
|
|
||||||
|
覆盖 COBOL 85 标准 + 部分 COBOL 2002 扩展，按 COBOL 语句功能分类：

|
||||||
|
|
||||||
|
现有 `test-data/cobol/` 下 33 个样本程序，按类别：
|
||||||
|
|
||||||
|
| 类别 | 程序数 | 文件名 | 覆盖的语句 |
|
||||||
|
|:-----|:------:|:-------|:-----------|
|
||||||
|
| matching | 10 | MT01-33 | IF, MOVE, PERFORM, OPEN/CLOSE/READ, WRITE |
|
||||||
|
| sort | 2 | ST01-02 | SORT, MERGE, OPEN, READ, WRITE |

|
||||||
|
|
||||||
|
### 2.4 解析器支持类型说明
|
||||||
|
|
||||||
|
解析器对语句的支持分三种等级:
|
||||||
|
|
||||||
|
| 等级 | 含义 | 语句 |
|
||||||
|
|:-----|:------|:------|
|
||||||
|
| ✅ **专用解析器** | core.py 中有 `_parse_*` 方法 | IF/EVALUATE/PERFORM/SEARCH/INITIALIZE/STRING/UNSTRING/CALL/ACCEPT/READ/WRITE/REWRITE/SET/INSPECT + 全部算术赋值(MOVE/COMPUTE/ADD/SUB/MULT/DIV) |
|
||||||
|
| ⚠️ **Pass-through** | 解析器无专用方法，跳过但不中断流程 | CLOSE/DELETE/DISPLAY/START/CONTINUE |
|
||||||
|
| ❌ **无处理** | 解析器无法识别，可能产生意外结果 | ALTER/USE/MERGE/SORT/RELEASE/RETURN/EXECUTE/GENERATE |
|
||||||
|
|
||||||
|
> **注意:** MERGE 和 SORT 在分类器 (classifier.py) 中有关键词检测，但在解析器中是 pass-through。
|
||||||
|
|
||||||
|

## 4. 测试金字塔
|
||||||
|
|
||||||
|
### 4.1 L0: 语句级单元测试 (cobol_testgen 解析层)
|
||||||
|
|
||||||
|
每类语句的解析逻辑应有独立的 pytest 测试：
|
||||||
|
|
||||||
|
```python
|
||||||
|
# tests/parametrized/test_statements/
|
||||||
|
# test_arithmetic_statements.py
|
||||||
|
# test_move_statements.py
|
||||||
|
# test_file_statements.py
|
||||||
|
# test_control_statements.py
|
||||||
|
# test_search_statements.py
|
||||||
|
# test_sort_statements.py
|
||||||
|
```
|
||||||
|
|
||||||
|
每个测试模式（xUnit parametrized × 样本文件）：
|
||||||
|
|
||||||
|
```python
|
||||||
|
@pytest.mark.parametrize("cbl_file,expected", [
|
||||||
|
("ST-ADD-TO.cbl", {"has_add": True, "branch_count": 2}),
|
||||||
|
("ST-ADD-GIVING.cbl", {"has_add": True, "has_giving": True}),
|
||||||
|
])
|
||||||
|
def test_statement_parse(cbl_file, expected):
|
||||||
|
source = (FIXTURES_DIR / cbl_file).read_text("utf-8")
|
||||||
|
struct = extract_structure(source)
|
||||||
|
# assert 解析结果匹配 expected
|
||||||
|
```
|
||||||
|
|
||||||
|
#### L0 测试清单
|
||||||
|
|
||||||
|
| 测试文件 | 测试点 | 测试数 |

|
||||||
|
| **合计** | **50 样本程序** | **~165** |
|
||||||
|
|
||||||
|
### 4.2 L1: 数据生成验证
|
||||||
|
|
||||||
|
验证 `generate_data()` 能否为每类语句生成覆盖所有分支的测试数据：
|
||||||
|
|

|
| # | 测试点 | 期待 |
|
||||||
|
|:-:|:-------|:------|
|
||||||
|
| DG-01 | 算术分支覆盖 | ADD/SUB/MULTIPLY/DIVIDE 每个变体 ≥ 1 条记录 |
|
||||||
|
| DG-02 | IF-ELSE 全覆盖 | 2 分支 = 2 条记录, nested IF = 2^n 部分覆盖 |

## 5. 样本程序规范
|
||||||
|
|
||||||
|
### 5.1 模板
|
||||||
|
|
||||||
|
每个样本程序必须包含：
|
||||||
|
|
||||||
|
```cobol
|
||||||
|
* ==== TYPE: ST-ADD-TO ====
|
||||||
|
* FEATURE: ADD x TO y (constant / variable)
|
||||||
|
* STATEMENT: ADD
|
||||||
|
* BRANCHES: 2, DECISIONS: 1
|
||||||
|
* COVERAGE: IF divisibility check
|
||||||
|
IDENTIFICATION DIVISION.
|
||||||
|
PROGRAM-ID. STADDTO.
|
||||||
|
DATA DIVISION.
|
||||||
|
WORKING-STORAGE SECTION.
|
||||||
|
01 WS-VALUE PIC 9(5) VALUE 100.
|
||||||
|
01 WS-RESULT PIC 9(5) VALUE 0.
|
||||||
|
PROCEDURE DIVISION.
|
||||||
|
MAIN-PROCEDURE.
|
||||||
|
ADD 50 TO WS-VALUE.
|
||||||
|
MOVE WS-VALUE TO WS-RESULT.
|
||||||
|
IF WS-RESULT = 150
|
||||||
|
DISPLAY 'OK: 100 + 50 = 150'
|
||||||
|
ELSE
|
||||||
|
DISPLAY 'ERROR: WRONG VALUE'.
|
||||||
|
STOP RUN.
|
||||||
|
```
|
||||||
|
|
||||||
|
### 5.2 样本程序质量要求
|
||||||
|
|
||||||
|
每个样本:
|
||||||
|
- 可被 `cobol_testgen preprocess` 正确预处理
|
||||||
|
- 有明确的分支决策点（至少 1 个 IF 或 EVALUATE）
|
||||||
|
- 至少 2 个分支路径
|
||||||
|
- 语法正确的 COBOL（简化但符合语法）
|
||||||
|
- 包含 `* BRANCHES: N` 元注释，便于自动验证
|
||||||
|
- 不使用外部文件操作（避免运行时环境依赖）除非测试文件操作
|
||||||
|
- 对 CICS/SQL 语句使用 `*> comment mock` 标记模拟
|
||||||
|
|
||||||
|
### 5.3 自动验证机制
|
||||||
|
|
||||||
|
新增 `test-data/validate_statements.py` 自动验证所有样本：
|
||||||
|
|
||||||
|
```bash
|
||||||
|
python test-data/validate_statements.py
|
||||||
|
```
|
||||||
|
|
||||||
|
验证内容:
|
||||||
|
1. ✅ 每个样本能被 preprocess 正确处理
|
||||||
|
2. ✅ extract_structure 返回非空 structure
|
||||||
|
3. ✅ BRANCHES 元注释与 struct.total_branches 一致
|
||||||
|
4. ✅ generate_data 至少生成 1 条记录
|
||||||
|
5. ✅ 无未捕获异常
|
||||||
|
6. 报告: `通过/N 失败/M` 汇总
|
||||||
|
|
||||||

## 7. 实施步骤
|
||||||
|
|
||||||
|
### Phase A: P0 样本编写 (32 个 .cbl)
|
||||||
|
|
||||||
|
```bash
|
||||||
|
mkdir -p test-data/cobol/statement_arithmetic/
|
||||||
|
mkdir -p test-data/cobol/statement_move/
|
||||||
|
mkdir -p test-data/cobol/statement_file/
|
||||||
|
mkdir -p test-data/cobol/statement_control/
|
||||||
|
mkdir -p test-data/cobol/statement_inspect/
|
||||||
|
```
|
||||||
|
|
||||||
|
编写 32 个样本后运行验证脚本确保语法正确。
|
||||||
|
|
||||||
|
### Phase B: L0 测试实现
|
||||||
|
|
||||||
|
```bash
|
||||||
|
mkdir -p tests/parametrized/test_statements/
|
||||||
|
```
|
||||||
|
|
||||||
|
8 个 parametrized 测试文件，覆盖 ~165 个测试点。
|
||||||
|
|
||||||
|
### Phase C: L1 数据生成验证
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# 验证所有 P0 样本
|
||||||
|
python -c "
|
||||||
|
from cobol_testgen import extract_structure, generate_data
|
||||||
|
import glob
|
||||||
|
for f in glob.glob('test-data/cobol/statement_*/*.cbl'):
|
||||||
|
src = open(f).read()
|
||||||
|
s = extract_structure(src)
|
||||||
|
d = generate_data(src)
|
||||||
|
print(f'{f}: branches={s[\"total_branches\"]}, records={len(d)}')
|
||||||
|
"
|
||||||
|
```
|
||||||
|
|
||||||
|
### Phase D: L2 分类器验证
|
||||||
|
|
||||||
|
```bash
|
||||||
|
python -c "
|
||||||
|
from hina.pipeline import classify_program
|
||||||
|
import glob
|
||||||
|
for f in glob.glob('test-data/cobol/statement_*/*.cbl'):
|
||||||
|
src = open(f).read()
|
||||||
|
r = classify_program(src)
|
||||||
|
print(f'{f}: {r[\"category\"]} conf={r[\"confidence\"]:.2f}')
|
||||||
|
"
|
||||||
|
```
|
||||||
|
|
||||||
|
### Phase E-F: P1/P2
|
||||||
|
|
||||||
|
按优先级逐步补充。

## 8. 已知限制
|
||||||
|
|
||||||
|
1. **CICS/SQL 语句**: 使用 `*>` 注释模拟，不实际编译。L0 仅测试关键词解析
|
||||||
|
2. **GO TO DEPENDING ON**: COBOL 85 标准，解析器支持但样本需跨段落跳转
|
||||||
|
3. **ALTER**: 已废弃但大型机遗产代码仍存在。解析器需补充 ALTER 语句节点
|
||||||
|
4. **DECLARATIVES**: 解析器 _BrParser 当前未处理 USE/DECLARATIVES 段
|
||||||
|
5. **MOVE CORRESPONDING**: 解析器支持 MOVE 但不支持 CORR 子句扩展
|
||||||
|
6. **MERGE OUTPUT PROCEDURE**: 解析器支持 MERGE 但不支持 PROCEDURE 扩展
|
||||||
|
7. **Windows 编码**: 样本统一 UTF-8，使用 `python -X utf8` 运行

## 9. Gap Analysis — 与完整 COBOL 85 标准的差异
|
||||||
|
|
||||||
|
### 9.1 总览
|
||||||
|
|
||||||
|
以下为计划与 COBOL 85 标准 + 主流程迁移场景的完整差异分析。
|
||||||
|
|
||||||
|
| 维度 | 标准语句数 | 计划覆盖 | 不覆盖 | 覆盖率 |
|
||||||
|
|:-----|:---------:|:--------:|:-----:|:-----:|
|
||||||
|
| COBOL 85 过程语句 | ~42 | 40 | 2 (ENTER, GENERATE) | **95%** |
|
||||||
|
| CICS 语句 (迁移相关) | ~10 | 7 | 3 | **70%** |
|
||||||
|
| SQL 语句 (迁移相关) | ~10 | 7 | 3 | **70%** |
|
||||||
|
| 分类器关键字样本 | ~11 | 7 | 4 | **64%** |
|
||||||
|
|
||||||
|
### 9.2 计划内但解析器需补充的语句
|
||||||
|
|
||||||
|
以下语句在计划中有样本，**但解析器 core.py 当前不支持**（pass-through 或缺失）：
|
||||||
|
|
||||||
|
| 语句 | 当前状态 | 需补充 | 影响 |
|
||||||
|
|:-----|:--------:|:-------|:------|
|
||||||
|
| DELETE FILE | ⚠️ pass-through | `_parse_delete()` | 解析器无法追踪文件删除操作 |
|
||||||
|
| START | ⚠️ pass-through | `_parse_start()` | 解析器无法追踪文件定位 |
|
||||||
|
| ALTER | ⚠️ pass-through | `_parse_alter()` | 覆盖遗留代码中的 ALTER 语句 |
|
||||||
|
| CONTINUE | ⚠️ pass-through | `_parse_continue()` | 低风险，CONTINUE 是空操作 |
|
||||||
|
| USE/DECLARATIVES | ❌ 无处理 | `_parse_use()` | 声明段解析，是大型机常见模式 |
|
||||||
|
| SORT | ⚠️ pass-through | `_parse_sort()` | 解析器无法追踪排序过程 |
|
||||||
|
| MERGE | ⚠️ pass-through | `_parse_merge_inline()` | 解析器无法追踪合并过程 |
|
||||||
|
| RELEASE / RETURN | ⚠️ pass-through | SORT/MERGE 子句 | 排序合并子语句 |
|
||||||
|
| MOVE CORRESPONDING | ❌ 无处理 | CORR 支持 | 低优先级，可延后 |
|
||||||
|
|
||||||
|
### 9.3 计划未覆盖的标准 COBOL 语句
|
||||||
|
|
||||||
|
| 语句 | 标准 | 不覆盖原因 | 建议 |
|
||||||
|
|:-----|:----:|:-----------|:-----|
|
||||||
|
| CANCEL | COBOL 85 | 释放程序内存，迁移中罕见 | **建议补充 P2** |
|
||||||
|
| COMMIT | COBOL 85 | 事务控制。大型机批处理程序常用 | **建议补充 P2** |
|
||||||
|
| ROLLBACK | COBOL 85 | 事务回滚，常与 COMMIT 搭配 | **建议补充 P2** |
|
||||||
|
| DISPLAY | COBOL 85 | 输出语句，不产生分支。解析器 classify_field_roles 已扫描读取追踪 | **建议补充 P2**（低优先级，仅需 L0 验证样本） |
|
||||||
|
| ENTER | COBOL 85 | 语言切换（汇编等），迁移中极罕见 | 可忽略 P3 |
|
||||||
|
| EXHIBIT | COBOL 85 | 命名 DISPLAY 变体，已过时 | 可忽略 P3 |
|
||||||
|
| GENERATE | COBOL 85 | Report Writer 功能，迁移不涉及 | 可忽略 P3 |
|
||||||
|
|
||||||
|
### 9.4 计划未覆盖的 CICS 语句
|
||||||
|
|
||||||
|
| 语句 | 用法 | 建议 |
|
||||||
|
|:-----|:-----|:------|
|
||||||
|
| **EXEC CICS LINK** | 程序间调用（最常用的 CICS 通信之一） | **建议补充 P1** |
|
||||||
|
| **EXEC CICS XCTL** | 程序间转移控制 | **建议补充 P1** |
|
||||||
|
| **EXEC CICS RETURN** | 返回至 CICS 调用链上层 | **建议补充 P1** |
|
||||||
|
| EXEC CICS ADDRESS | 获取/设置工作区地址 | 可忽略 P3 |
|
||||||
|
| EXEC CICS HANDLE | 异常条件处理 | 可忽略 P3 |
|
||||||
|
|
||||||
|
### 9.5 计划未覆盖的 SQL 语句
|
||||||
|
|
||||||
|
| 语句 | 用法 | 建议 |
|
||||||
|
|:-----|:-----|:------|
|
||||||
|
| **EXEC SQL COMMIT** | 事务提交（嵌入式 SQL 基本语句） | **建议补充 P2** |
|
||||||
|
| **EXEC SQL ROLLBACK** | 事务回滚 | **建议补充 P2** |
|
||||||
|
| EXEC SQL CONNECT | 数据库连接 | P3 |
|
||||||
|
| EXEC SQL PREPARE | 动态 SQL 预编译 | P3 |
|
||||||
|
|
||||||
|
### 9.6 分类器关键字样本覆盖不足
|
||||||
|
|
||||||
|
HINA classifier 的 L1_RULES 中有 4 个关键字**当前没有任何独立的 COBOL 样本验证**：
|
||||||
|
|
||||||
|
| 分类器关键字 | 匹配规则 | 现有样本 | 建议 |
|
||||||
|
|:-------------|:---------|:--------:|:-----|
|
||||||
|
| **IS INITIAL** | `PROGRAM-ID. X IS INITIAL.` | ❌ 无 | **P1 — 新增 ST-CLS-INITIAL.cbl** |
|
||||||
|
| **SYSIN** | `SYSIN` 关键字 | ❌ 无 | **P1 — 新增 ST-CLS-SYSIN.cbl** |
|
||||||
|
| **ORGANIZATION IS** | `ORGANIZATION IS INDEXED/RELATIVE` | ❌ 无 | **P1 — 新增 ST-CLS-ORG.cbl** |
|
||||||
|
| **ALTERNATE RECORD KEY** | `ALTERNATE RECORD KEY IS ...` | ❌ 无 | **P1 — 新增 ST-CLS-ALTKEY.cbl** |
|
||||||
|
|
||||||
|
这些不会影响平台功能，但 **classifier 的测试套件缺少对这 4 个分类的确信度验证**。如果没有样本阻止回归，未来重构 keyword 匹配时可能无意中破坏这 4 个分类而测试不敏感。
|
||||||
|
|
||||||
|
### 9.7 矩阵不准确性追踪
|
||||||
|
|
||||||
|
| 行 | 原值 | 实际值 | 修正版本 |
|
||||||
|
|:---|:-----|:-------|:---------|
|
||||||
|
| DELETE (FILE) | ✅ 解析支持 | ⚠️ 穿通 | v1.0 已修正 |
|
||||||
|
| START | ✅ 解析支持 | ⚠️ 穿通 | v1.0 已修正 |
|
||||||
|
| CLOSE | ✅ 解析支持 | ⚠️ 穿通 | v1.0 已修正 |
|
||||||
|
| SORT | ✅ 解析支持 | ⚠️ 穿通 (关键词检测) | v1.0 已修正 |
|
||||||
|
| MERGE | ✅ 解析支持 | ⚠️ 穿通 (关键词检测) | v1.0 已修正 |
|
||||||
|
| RELEASE/RETURN | ✅ 解析支持 | ⚠️ 穿通 (SORT 子句) | v1.0 已修正 |
|
||||||
|
| ALTER | ✅ 解析支持 | ⚠️ 穿通 (无解析器) | v1.0 已修正 |
|
||||||
|
| CONTINUE | ✅ 解析支持 | ⚠️ 穿通 | v1.0 已修正 |
|
||||||
|
| PERFORM 系列 | 矩阵缺失 | ✅ 解析支持 | v1.0 已添加 |
|
||||||
|
| OPEN (OUTPUT/I-O) | ✅ 解析支持 | ⚠️ 扫描 (open_pattern) | v1.0 已修正 |
|
||||||
|
| MOVE CORRESPONDING | ⚠️ 部分 | ❌ 不支持 | v1.0 已修正 |
|
||||||
|
| USE/DECLARATIVES | ⚠️ 部分 | ❌ 无处理 | v1.0 已修正 |
|
||||||
|
| EXECUTE | ⚠️ 部分 | ⚠️ 穿通 | v1.0 已修正 |
|
||||||
|
|
||||||
|
### 9.8 CICS/SQL 注释模拟限制
|
||||||
|
|
||||||
|
当前 CICS/SQL 样本使用 `*>` 注释关键词模拟：
|
||||||
|
```
|
||||||
|
*> EXEC CICS LINK PROGRAM('PGM01')
|
||||||
|
*> COMMAREA(WS-COMMAREA)
|
||||||
|
*> END-EXEC.
|
||||||
|
```
|
||||||
|
|
||||||
|
这意味着：
|
||||||
|
- `extract_structure()` **无法**从注释中提取分支结构
|
||||||
|
- 分类器 `classify_program()` 仍能检测关键词 → 正确分类
|
||||||
|
- 注释模拟样本**不经过 GnuCOBOL 编译检验语法正确性**
|
||||||
|
|
||||||
|
如果需要编译级验证，需要 WSL 中安装 IBM Enterprise COBOL 或 GnuCOBOL 的 CICS 支持库（不在当前范围）。
|
||||||
|
|
||||||
|
### 9.9 建议的补充优先级
|
||||||
|
|
||||||
|
基于差异分析，建议的补充顺序：
|
||||||
|
|
||||||
|
| 批次 | 内容 | 语句数 | 理由 |
|
||||||
|
|:-----|:------|:------:|:------|
|
||||||
|
| **立即 (当前 P0)** | 按现有计划执行 | 32 | 解析器已完全支持，仅缺样本 |
|
||||||
|
| **P1 + 补充** | CICS LINK/XCTL/RETURN + 分类器关键字 4 个 | 7 | 迁移场景高频使用 + 分类器测试缺口 |
|
||||||
|
| **P2 补充** | CANCEL/DISPLAY + SQL COMMIT/ROLLBACK | 4 | 标准语句缺失补全 |
|
||||||
|
| **P3 (可忽略)** | ENTER/EXHIBIT/GENERATE/CICS ADDRESS/HANDLE | 5 | 极低使用率或已过时 |
