优化款号管理界面功能

- 修复删除类目时删除错误行的问题
- 移除"快速添加标准类目"功能
- 统一界面文案："自定义类目"改为"选择类目"
- 简化按钮文案："新增/编辑款号"改为"新增款号"

+## 运行测试
+
+### 运行单个模块测试
+```bash
+# 登录测试
+python test\test_login_gui.py -v
+
+# 库存测试
+python test\test_stock_gui.py -v
+
+# 原料测试
+python test\test_raw_material_gui.py -v
+
+# 款式测试
+python test\test_garment_gui.py -v
+
+# 采购单测试
+python test\test_purchase_order_gui.py -v
+```
+
+### 运行所有GUI测试
+```bash
+cd test
+python -m unittest test_login_gui.py test_stock_gui.py test_raw_material_gui.py test_garment_gui.py test_purchase_order_gui.py -v
+```
+
+## 测试特点
+
+### 1. 真实GUI交互
+- 模拟用户填写表单
+- 模拟点击按钮
+- 模拟选择下拉框
+- 模拟输入搜索关键词
+
+### 2. 业务逻辑验证
+- 验证重复数据拒绝
+- 验证空值验证
+- 验证数据计算正确性
+- 验证过滤和搜索功能
+
+### 3. 独立测试环境
+- 每个测试使用临时数据库
+- 测试之间互不干扰
+- 自动清理测试数据
+
+### 4. 自动化消息框
+- Mock了QMessageBox以便自动化测试
+- 不需要人工点击确认对话框
+- 可以验证警告和错误消息
+
+## 测试架构
+
+```
+test/
+├── test_login_gui.py          # 登录对话框测试
+├── test_stock_gui.py          # 库存管理测试
+├── test_raw_material_gui.py   # 原料管理测试
+├── test_garment_gui.py        # 款式管理测试
+├── test_purchase_order_gui.py # 采购单生成测试
+└── README_GUI_TESTS.md        # 本文档
+```
+
+## 依赖项
+
+- Python 3.x
+- PyQt5
+- sqlite3 (内置)
+- unittest (内置)
+
+## 注意事项
+
+1. 测试需要在有GUI环境的系统上运行
+2. 测试会创建临时数据库文件，测试后自动清理
+3. 所有消息框已被Mock，不会弹出实际对话框
+4. 测试使用独立的QApplication实例
+
+## 扩展测试
+
+如需添加新的GUI测试，请参考现有测试文件的结构：
+
+1. 继承 `unittest.TestCase`
+2. 在 `setUpClass` 中创建 `QApplication` 实例
+3. 在 `setUp` 中创建临时数据库和对话框
+4. Mock消息框以便自动化
+5. 在 `tearDown` 中清理资源
+6. 编写具体的测试方法
+
+## 测试覆盖率
+
+当前GUI测试覆盖了以下核心功能：
+- ✓ 用户登录和密码管理
+- ✓ 原料库管理（增删改查）
+- ✓ 库存管理和计算
+- ✓ 款式管理
+- ✓ 采购单生成和计算
+
+## 维护建议
+
+1. 每次修改GUI代码后运行相关测试
+2. 添加新功能时同步添加GUI测试
+3. 定期运行所有测试确保系统稳定性
+4. 保持测试代码的可读性和可维护性
