根因分析

pytest.mark.skipif 需要同时提供条件和 reason 关键字。将字符串作为第一个位置参数传入（常见错误）会让 pytest 视为无效条件。

English

pytest.mark.skipif requires both a condition and a reason keyword. Passing a string as the first positional arg (a common mistake) makes pytest treat it as an invalid condition.

解决方案

  1. 98% 成功率 
    Use keyword arguments:
  @pytest.mark.skipif(sys.platform == 'win32', reason='POSIX-only')
  def test_x(): ...
  2. 95% 成功率 
    For module-level skips:
  pytestmark = pytest.mark.skipif(condition, reason='...')

无效尝试

常见但无效的做法:

  1. 90% 失败

    Unconditionally skips the test even on platforms where it should run.

  2. 80% 失败

    Positional args are not supported for reason; must be keyword.
