## About

# Tests Are The Truth / 测试即结论

> Work ends when the test passes, not when the code is written.
> 工作的结束是测试通过,不是代码写完。

## The discipline / 纪律

1. Code written ≠ done. There must be an executable check proving the behavior is correct.
   写完代码不等于完成,必须有可执行的验证证明行为正确。
2. Tests must be falsifiable — not just "it ran", but the error paths too (bad input, dropped connection, timeout).
   测试必须可证伪——不只是"跑通了",还要覆盖错误路径(非法输入、断连、超时)。
3. A smoke test is the floor: run it end-to-end once and observe *actual* behavior, never imagined behavior.
   冒烟测试是底线:端到端真跑一次,观察**实际**行为,不靠想象。
4. When you hand a task to another agent, the task description must spell out the verification step.
   把任务派给别的 agent 时,任务描述必须写明验证步骤。(派子任务的完整必含项见 agent-team 的「派子任务必含清单」)
5. Test what you changed, not what you didn't. Target the actual change point.
   测你改的,不是测你没改的,靶向实际变更点。

## When this triggers / 触发时机

- About to say "done / should be fine / it works".
- About to merge a PR or close an issue.
- Handing a sub-task to an agent (its description must include verification).
- Just fixed a bug and about to wrap up.

## Done criterion (verifiable) / 完成判据（可验证）

Every completion claim ends in this exact shape:

```
✅ Passed:   
❌ Failed:   
⚠️ Untested: 
```

✅ The claim is backed by a real run with this three-part conclusion.
⚠️ Only the happy path ran — error/boundary paths still untested. Put them in the ⚠️ line; not fully done.
❌ You said "done" with no executed test. Not done — run it.
