+
+AirTst 是测试运行器。支持多框架统一执行和结构化结果报告。
+
+## 支持的框架
+
+| 框架 | --framework 值 | 语言 |
+|------|---------------|------|
+| CTest / GoogleTest | `googletest` | C++ |
+| pytest | `pytest` | Python |
+| jest / vitest | `jest` | TypeScript |
+| go test | `go` | Go |
+| cargo test | `cargo` | Rust |
+
+## 子命令
+
+### run — 执行测试
+
+```bash
+python scripts/airplan.py --mode tst --project . --sub run --task-id T-001 --framework googletest
+```
+
+参数：
+- `--task-id`：关联任务 ID
+- `--framework`：测试框架（见上表）
+
+返回 `{task_id, framework, total, passed, failed}`。emit `test.run` 事件。
+
+制品：`AirPlan/state/airtst/reports/{task_id}-{ts}.json`
+
+### status — 查看测试状态
+
+```bash
+python scripts/airplan.py --mode tst --project . --sub status
+```
+
+## 集成路径
+
+**Arc 注入的边界测试任务执行**：Arc 规划的 `T-TEST-*` 任务执行时调 tst run：
+```bash
+python scripts/airplan.py --mode tst --project . --sub run --task-id T-TEST-001 --framework googletest
+```
+
+**Do Worker 完成前自测**：Worker finish 前可调 tst 验证：
+```bash
+python scripts/airplan.py --mode tst --project . --sub run --task-id {tid} --framework {fw}
+```
