=================== Tornado OpenAPI 3 =================== .. image:: https://github.com/correl/tornado-openapi3/actions/workflows/test.yml/badge.svg?branch=master :target: https://github.com/correl/tornado-openapi3/actions/workflows/test.yml?branch=master .. image:: https://codecov.io/gh/correl/tornado-openapi3/branch/master/graph/badge.svg?token=CTYWWDXTL9 :target: https://codecov.io/gh/correl/tornado-openapi3 .. image:: https://readthedocs.org/projects/tornado-openapi3/badge/ :target: https://tornado-openapi3.readthedocs.io .. image:: https://img.shields.io/badge/code%20style-black-000000.svg :target: https://github.com/psf/black Tornado OpenAPI 3 request and response validation library. Provides integration between the `Tornado`_ web framework and `Openapi-core`_ library for validating request and response objects against an `OpenAPI 3`_ specification. Full documentation is available at https://tornado-openapi3.readthedocs.io Usage ===== Adding validation to request handlers ------------------------------------- .. code:: python import tornado.ioloop import tornado.web from tornado_openapi3.handler import OpenAPIRequestHandler class MyRequestHandler(OpenAPIRequestHandler): spec_dict = { "openapi": "3.0.0", "info": { "title": "Simple Example", "version": "1.0.0", }, "paths": { "/": { "get": { "responses": { "200": { "description": "Index", "content": { "text/html": { "schema": {"type": "string"}, } }, } } } } }, } class RootHandler(MyRequestHandler): async def get(self): self.finish("Hello, World!") if __name__ == "__main__": app = tornado.web.Application([(r"/", RootHandler)]) app.listen(8888) tornado.ioloop.IOLoop.current().start() Validating responses in tests ----------------------------- .. code:: python import unittest import tornado.web from tornado_openapi3.testing import AsyncOpenAPITestCase class RootHandler(tornado.web.RequestHandler): async def get(self): self.finish("Hello, World!") class BaseTestCase(AsyncOpenAPITestCase): spec_dict = { "openapi": "3.0.0", "info": { "title": "Simple Example", "version": "1.0.0", }, "paths": { "/": { "get": { "responses": { "200": { "description": "Index", "content": { "text/html": { "schema": {"type": "string"}, } }, } } } } }, } def get_app(self): return tornado.web.Application([(r"/", RootHandler)]) def test_root_endpoint(self): response = self.fetch("/") self.assertEqual(200, response.code) self.assertEqual(b"Hello, World!", response.body) if __name__ == "__main__": unittest.main() Contributing ============ Getting Started --------------- This project uses `Poetry`_ to manage its dependencies. To set up a local development environment, just run: .. code:: sh poetry install Formatting Code --------------- The `Black`_ tool is used by this project to format Python code. It is included as a development dependency, and should be run on all committed code. To format code prior to committing it and submitting a PR, run: .. code:: sh poetry run black . Running Tests ------------- `pytest`_ is the preferred test runner for this project. It is included as a development dependency, and is configured to track code coverage, `Flake8`_ style compliance, and `Black`_ code formatting. Tests can be run in your development environment by running: .. code:: sh poetry run pytest Additionally, tests can be run using `tox`_, which will run the tests using multiple versions of both Python and Tornado to ensure broad compatibility. Configuring Hypothesis ^^^^^^^^^^^^^^^^^^^^^^ Many of the tests make use of `Hypothesis`_ to specify their expectations and generate a large volume of randomized test input. Because of this, the tests may take a long time to run on slower computers. Two profiles are defined for Hypothesis to use which can be selected by setting the ``HYPOTHESIS_PROFILE`` environment variable to one of the following values: ``ci`` Runs tests using the default Hypothesis settings (100 examples per test) and no completion deadline. ``dev`` The fastest profile, meant for local development only. Uses only 10 examples per test with no completion deadline. .. _Black: https://github.com/psf/black .. _Flake8: https://flake8.pycqa.org/ .. _Hypothesis: https://hypothesis.readthedocs.io/ .. _OpenAPI 3: https://swagger.io/specification/ .. _Openapi-core: https://github.com/p1c2u/openapi-core .. _Poetry: https://python-poetry.org/ .. _Tornado: https://www.tornadoweb.org/ .. _pytest: https://pytest.org/ .. _tox: https://tox.readthedocs.io/
