How to test single file under pytest


simply run pytest with the path to the file

something like

pytest tests/unit/some_test_file.py


This is pretty simple:

$ pytest -v /path/to/test_file.py

The -v flag is to increase verbosity. If you want to run a specific test within that file:

$ pytest -v /path/to/test_file.py::test_name

If you want to run test which names follow a patter you can use:

$ pytest -v -k "pattern_one or pattern_two" /path/to/test_file.py

You also have the option of marking tests, so you can use the -m flag to run a subset of marked tests.

test_file.py

def test_number_one():    """Docstring"""    assert 1 == 1@pytest.mark.run_these_pleasedef test_number_two():    """Docstring"""    assert [1] == [1]

To run test marked with run_these_please:

$ pytest -v -m run_these_please /path/to/test_file.py


This worked for me:

python -m pytest -k some_test_file.py

This works for individual test functions too:

python -m pytest -k test_about_something
