python - 如何在 pytest -k 命令行选项中包含正斜杠“/”

问题描述

我正在尝试使用 pytest -k 选项来过滤掉特定的测试。过滤器不起作用并在包含正斜杠“/”时返回错误。我尝试用一​​个和两个反斜杠转义它，但仍然是同样的错误。知道怎么做吗？

ERROR: Wrong expression passed to '-k':

解决方案

-k是（有点故意）不灵活的——它并不意味着允许所有输入进行匹配。

也就是说，有两种方法可以做你想做的事：

  1. 稍微调整一下-k表情： pytest -k 'test_pinger and ping_topoA_ADI_US_PLEAFS_L0_ipv4'
  2. 直接使用测试ID （这似乎是你正在尝试的）：pytest 'tools/test_pinger.py::test_pinger[pingtrace/ADI/ping_topoA_ADI_US_PLEAFS_L0_ipv4.yml]'
