## 解决方案

1. **Create the test suite directory with __init__.py** (95% 成功率)
   ```
   Run: mkdir tests; touch tests/__init__.py; touch tests/test_example.py
   ```
2. **Correct the test_suite path in setup.cfg** (90% 成功率)
   ```
   Set test_suite = tests.test_suite (if using a module).
   ```

## 无效尝试

- **Creating an empty tests directory** — An empty directory is not a valid test suite. (80% 失败率)
- **Removing the test_suite configuration** — Tests will not run automatically. (70% 失败率)
