如何在 pytest -k 命令行选项中包含正斜杠“/”

Question

我正在尝试使用 pytest -k 选项来过滤掉特定的测试。当过滤器包含正斜杠“/”时，过滤器不起作用并且 returns 出错。我尝试用一个和两个反斜杠将其转义，但仍然出现相同的错误。知道怎么做吗？

ERROR: Wrong expression passed to '-k': 
test_pinger[pingtrace/ADI/ping_topoA_ADI_US_PLEAFS_L0_ipv4.yml: 
at column 22: unexpected character "/"

$ pytest tools/test_pinger.py --testinfo topoA_PEs.yml --params_file topoA_r28_params.yml --ulog -s --collect-only -k "test_pinger[pingtrace/ADI/ping_topoA_ADI_US_PLEAFS_L0_ipv4.yml"

-k（有点故意）不灵活——它并不意味着允许所有输入进行匹配。

就是说，有两种方法可以满足您的需求：

稍微调整一下你的-k表情：pytest -k 'test_pinger and ping_topoA_ADI_US_PLEAFS_L0_ipv4'
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]'
