"""
Basic Text Replace E2E Tests (自动化版本)

测试基本的文本查找和替换功能。

测试场景:
1. 简单文本替换（全部）
2. 简单文本替换（首个）
3. 替换为空（删除）
4. 多行文本替换
5. 特殊字符替换
6. 长文本替换

运行方式:
    uv run python manual_tests/replace_text_e2e/test_basic_replace.py --test 1
    uv run python manual_tests/replace_text_e2e/test_basic_replace.py --test all
    uv run python manual_tests/replace_text_e2e/test_basic_replace.py --list
