Use @pytest.mark.only to run a single test
Project description
Only run tests marked with @pytest.mark.only. If none are marked, all tests run as usual.
Borrowed from mocha.
Installation
pip install pytest-only
Usage
Use it on functions
import pytest

Disable for single test run
To run all the tests, regardless of whether @pytest.mark.only is used, pass the --no-only flag to pytest:
$ py.test --no-only
If --no-only has already been passed (perhaps by way of addopts in pytest.ini), use the --only flag to re-enable it:
$ py.test --no-only --only
Development
Install the test/dev requirements
$ pip install -r dev-requirements.txt
Run the tests
$ py.test
Run the tests on all currently-supported platforms
$ tox
