If using pytest, you can specify exclusive paths or files to test in setup.cfg (see docs):

[pytest]
# a directory
testpaths = tests

# exact file(s)
python_files = tests/test1.py tests/test2.py

It looks like if you include the python_files and testpaths parameters, then the python_files will only be used.
