Suppose we have multiple files , say test_sample2.py , test_sample3.py. To run all the tests from all the files in the folder and subfolders we need to just run the pytest command. This will run all the filenames starting with test_ and the filenames ending with _test in that folder and subfolders under that folder.
Pytest supports several ways to run and select tests from the command-line. This will run tests which contain names that match the given string expression (case-insensitive), which can include Python operators that use filenames, class names and function names as variables.
Running pytest without mentioning a filename will run all files of format test_*. py or *_test.py in the current directory and subdirectories. Pytest automatically identifies those files as test files.
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_please
def 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
