您可以使用-k命令行选项来指定一个表达式，该表达式实现了测试名称上的子字符串匹配，而不是-m提供的标记的精确匹配。这使得基于他们的名字选择测试变得很容易:
Using -k expr to select tests based on their name¶
You can use the -k command line option to specify an expression which implements a substring match on the test names instead of the exact match on markers that -m provides. This makes it easy to select tests based on their names:
$ pytest -v -k http # running with the above defined example module
=========================== test session starts ============================

test_server.py::test_send_http PASSED [100%]
================== 1 passed, 3 deselected in 0.12 seconds ==================
And you can also run all tests except the ones that match the keyword:
$ pytest -k "not send_http" -v

Or to select “http” and “quick” tests:
$ pytest -k "http or quick" -v
