根因分析

`@pytest.mark.skipif("sys.platform == 'win32'")` 传入的是字符串，pytest 在自己的命名空间中求值；如果那里未导入 `sys`，表达式可能报错或被视为真值，导致所有平台都被跳过。

English

`@pytest.mark.skipif("sys.platform == 'win32'")` was passed a string, which pytest evaluates in its own namespace; if `sys` is not imported there, the expression may raise or be treated as truthy, skipping on all platforms.

    import sys
import pytest

@pytest.mark.skipif(sys.platform == "win32", reason="POSIX only")
def test_symlink():
    ...

    import sys

@pytest.mark.skipif(lambda: sys.platform == "win32", reason="POSIX only")
def test_symlink():

无效尝试

常见但无效的做法:

  1. 80% 失败

    The skipif expression is evaluated at collection time in the marker namespace, not inside the test body.

  2. 90% 失败

    Skips unconditionally on every platform, permanently disabling the test.
