"""
语法审查 (GrammarCheckReviewer.check_grammar) 全链路测试

测试范围（仅限 sensitive_word_check.py 自身逻辑）：
  1. Prompt 模板：YAML 配置结构 → prompt_loader 加载 → 变量填充
  2. 模型调用：check_grammar → model_client.get_model_generate_invoke(function_name="sensitive_check")
  3. 结果封装：模型响应 → ReviewResult(details={name, response}, execution_time)
  4. 异常处理：超时/错误 → ReviewResult(success=False)
  5. 推送集成：state.progress_manager 异步推送

用法：
  cd <project_root>
  set PYTHONPATH=<project_root>
  pytest utils_test/Sensitive_Test/test_grammar_check_chain.py -v
