### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

When it fails it generally looks something like this:

```
poetry run coverage run -m pytest
============================= test session starts ==============================

```

### Expected Behavior

_No response_

### Steps To Reproduce

_No response_

### Environment

```

### Anything else?

_No response_

先檢查 Makefile:136 中的 coverage 目標，並重現其中顯示的 `poetry run coverage run -m pytest` 命令。檢視整合測試和屬性測試在哪裡停止進行，然後確認完整的 coverage 執行能在未達到 600000ms CI 逾時前完成。
