为项目添加测试用例和测试配置

- 添加了完整的测试框架 (pytest)
- 为所有主要模块添加了单元测试
- 添加了测试配置文件 (pyproject.toml)
- 更新了 requirements.txt 以包含测试依赖
- 添加了测试指南 (tests/README.md)

这些测试涵盖了:
- utils.py 模块的所有功能
- config.py 模块的配置加载和环境变量处理
- ai_handler.py 模块的AI处理和通知功能
- prompt_utils.py 模块的prompt生成和配置更新
- scraper.py 模块的核心爬虫功能
- 各主要脚本的入口点测试

测试使用了pytest和unittest.mock来模拟外部依赖，确保测试的独立性和可重复性。

+# 测试指南
+
+本项目使用 pytest 作为测试框架。以下是运行测试的指南。
+
+## 安装依赖
+
+在运行测试之前，请确保已安装所有开发依赖项：
+
+```bash
+pip install -r requirements.txt
+```
+
+## 运行测试
+
+### 运行所有测试
+
+```bash
+pytest
+```
+
+### 运行特定测试文件
+
+```bash
+pytest tests/test_utils.py
+```
+
+### 运行特定测试函数
+
+```bash
+pytest tests/test_utils.py::test_safe_get
+```
+
+### 生成覆盖率报告
+
+```bash
+coverage run -m pytest
+coverage report
+coverage html  # 生成 HTML 报告
+```
+
+## 测试文件结构
+
+```
+tests/
+├── __init__.py
+├── conftest.py          # 共享测试配置和 fixtures
+├── test_ai_handler.py   # ai_handler.py 模块的测试
+├── test_config.py       # config.py 模块的测试
+├── test_login.py        # login.py 脚本的测试
+├── test_prompt_generator.py  # prompt_generator.py 脚本的测试
+├── test_prompt_utils.py # prompt_utils.py 模块的测试
+├── test_scraper.py      # scraper.py 模块的测试
+├── test_spider_v2.py    # spider_v2.py 脚本的测试
+└── test_utils.py        # utils.py 模块的测试
+```
+
+## 编写新测试
+
+1. 在 `tests/` 目录中创建新的测试文件，文件名应以 `test_` 开头
+2. 使用 `test_` 前缀命名测试函数
+3. 为异步函数使用 `@pytest.mark.asyncio` 装饰器
+4. 使用 `unittest.mock` 模块模拟外部依赖和副作用
+
+## 注意事项
+
+1. 一些测试可能需要复杂的模拟，特别是涉及 Playwright 的测试
+2. 某些测试可能需要实际的网络连接或外部服务
+3. 测试数据应尽可能使用模拟数据而不是真实数据
