Specify which pytest tests to run from a file

How do I select which pytest tests to run from a file?

For example, a file foo.txt containing a list of tests to be executed:

tests_directory/foo.py::test_001
tests_directory/bar.py::test_some_other_test

Similarly,

• Is there a way to select multiple tests, having no common pattern in test name, from different directories with pytest? pytest -k allows a single pattern. One option is to have a pytest.mark against each test, but my requirement is to run different combination of tests from different files.
• Is there a way to specify multiple patterns and a test file name for each pattern?
• Is there a way to specify the exact test paths in a file and feed that file as an input to pytest?
• Is there a hook function that can be utilized for this purpose?
