## 解决方案

1. **** (90% 成功率)
   ```
   Use pytest.skip() instead if the test is not yet ready: `pytest.skip('Test not implemented')`
   ```
2. **** (95% 成功率)
   ```
   Implement the missing logic and remove the fail statement.
   ```

## 无效尝试

- **** — The fail might be intentional to indicate an unimplemented test; removing it hides the gap. (70% 失败率)
- **** — This turns a failing test into a passing one, which can mask real issues. (90% 失败率)
