根因分析

现代 pytest 中 `@pytest.mark.skip` 和 `@pytest.mark.skipif` 需要 `reason=` 关键字；省略会触发弃用警告，在 `-W error` 下变成错误。

English

`@pytest.mark.skip` and `@pytest.mark.skipif` require a `reason=` keyword in modern pytest; omitting it triggers a deprecation warning that becomes an error under `-W error`.

解决方案

  1. 97% 成功率 
    Always pass a reason:
@pytest.mark.skip(reason='requires GPU')
def test_cuda(): ...

@pytest.mark.skipif(sys.platform == 'win32', reason='POSIX only')
def test_fork(): ...
  2. 90% 成功率 
    Or use `pytest.importorskip` for optional deps:
np = pytest.importorskip('numpy', reason='numpy not installed')

无效尝试

常见但无效的做法:

  1. 80% 失败

    Suppresses all deprecations, hiding real issues across the suite.

  2. 75% 失败

    Changes semantics: xfail expects failure, skip does not run; tests may start passing and turn XPASS.
