# TypeError: skipIf() missing 1 required positional argument: 'condition'

- **ID:** `python/unittest-skipif-condition`
- **Domain:** python
- **Category:** type_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

unittest.skipIf装饰器需要两个参数：条件和原因，如果缺少条件，会报错。

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 3.10 | active | — | — |

## Workarounds

1. **** (100% success)
   ```
   condition = sys.version_info < (3, 8)
@unittest.skipIf(condition, 'Python version too old')
   ```
2. **** (95% success)
   ```
   @pytest.mark.skipif(condition, reason='Python version too old')
   ```

## Dead Ends

- **** — 测试将无法跳过。 (90% fail)
- **** — skip不需要条件，但无法根据条件动态跳过。 (70% fail)
