# Regression Tests

防止改坏现有功能的回归测试套件。

## 运行测试

```bash
cd skills/hand-drawn-diagram
python3 tests/run_tests.py
```

## 测试覆盖

| Fixture | 覆盖点 |
|---------|--------|
| `01_sketch_basic` | sketch 风格基础架构生成 |
| `02_flat_style` | flat 风格浅色主题 |
| `03_semantic_shapes` | 语义节点映射 (double/cylinder/hexagon/cloud) |
| `04_connections` | 组件连接 (Connection) |
| `05_containers` | 分组容器 (Container) |
| `06_html_output` | HTML 完整页面输出 |

## 添加新 Fixture

1. 在 `tests/fixtures/` 创建 JSON 文件
2. 格式：

```json
{
  "name": "my_feature",
  "description": "描述",
  "type": "quick_architecture",
  "params": {
    "title": "...",
    "layers": [...],
    "output": "__TMP__/my_feature.svg",
    "style": "sketch",
    "format": "svg"
  },
  "assertions": [
    {"check": "contains", "text": "预期文字"},
    {"check": "contains_tag", "tag": "<rect", "min_count": 2}
  ]
}
```

### Assertion 类型

- `not_empty` — 输出非空
- `contains` / `text` — 内容包含指定文字
- `contains_tag` / `tag` / `min_count` — SVG/HTML 标签出现次数 ≥ min_count
