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:
def mytest1():
pass
def mytest2():
pass
pytest -v -k mytest1
To exclude test case using not keyword inside double quotes. Below code will execute mytest2 not mytest1.
pytest -k "not mytest1" -v
You can use or keyword to select multiple test cases matching name or keyword. Below code will execute both test cases.
pytest -k "mytest1 or mytest2" -v
