A pytest plugin for `Sanic <http://sanic.readthedocs.io/en/latest/>`_. It helps you to test your code asynchronously.

This plugin provides:

* very easy testing with async coroutines
* common and useful fixtures
* test_client for Sanic application
* test_server for Sanic application


You can find out more here:

http://pytest-sanic.readthedocs.io/en/latest/


-------
Install
-------

.. code::

pip install pytest-sanic


-----------
Quick Start
-----------

You don't have to load ``pytest-sanic`` explicitly. ``pytest`` will do it for you. Just write tests like,

.. code-block:: python

async def test_sanic_db_find_by_id(app):
"""
Let's assume that, in db we have,
{
"id": "123",
"name": "Kobe Bryant",
"team": "Lakers",
}
"""
doc = await app.db["players"].find_by_id("123")
assert doc.name == "Kobe Bryant"
assert doc.team == "Lakers"


--------
Fixtures
--------

Some fixtures for easy testing.

``loop``
~~~~~~~~

``pytest-sanic`` creates an event loop and injects it as a fixture. ``pytest`` will use this event loop to run your ``async tests``.
By default, fixture ``loop`` is an instance of `asyncio.new_event_loop`. But `uvloop` is also an option for you, by simpy passing
``--loop uvloop``. Keep mind to just use one single event loop.


``unused_port``
~~~~~~~~~~~~~~

an unused TCP port on the localhost.


``test_server``
~~~~~~~~~~~~~~

Creates a TestServer instance by giving a ``Sanic`` application. It's very easy to utilize ``test_server`` to create your `Sanic`
application server for testing.

.. code-block:: python

@pytest.yield_fixture
def app():
app = Sanic("test_sanic_app")

@app.route("/test_get", methods=['GET'])
async def test_get(request):
return response.json({"GET": True})

yield app

@pytest.fixture
def sanic_server(loop, app, test_server):
return loop.run_until_complete(test_server(app))

You can also very easily override this ``loop`` fixture by creating your own, simply like,

.. code-block:: python

@pytest.yield_fixture
def loop():
loop = MyEventLoop()
yield loop
loop.close()


``test_client``
~~~~~~~~~~~~~~

Creates a TestClient instance by giving a ``Sanic`` application. You can simply have a client by using ``test_client``, like

.. code-block:: python

@pytest.yield_fixture
def app():
app = Sanic("test_sanic_app")

@app.route("/test_get", methods=['GET'])
async def test_get(request):
return response.json({"GET": True})

@app.route("/test_post", methods=['POST'])
async def test_post(request):
return response.json({"POST": True})

@app.route("/test_put", methods=['PUT'])
async def test_put(request):
return response.json({"PUT": True})

@app.route("/test_delete", methods=['DELETE'])
async def test_delete(request):
return response.json({"DELETE": True})

@app.route("/test_patch", methods=['PATCH'])
async def test_patch(request):
return response.json({"PATCH": True})

@app.route("/test_options", methods=['OPTIONS'])
async def test_options(request):
return response.json({"OPTIONS": True})

@app.route("/test_head", methods=['HEAD'])
async def test_head(request):
return response.json({"HEAD": True})

@app.websocket("/test_ws")
async def test_ws(request, ws):
data = await ws.recv()
await ws.send(data)

yield app

@pytest.fixture
def test_cli(loop, app, test_client):
return loop.run_until_complete(test_client(app, protocol=WebSocketProtocol))

small notes:

``test_cli.ws_connect`` does not work in ``sanic.__version__ <= '0.5.4'``, because of a Sanic bug, but it
has been fixed in master branch. And ``websockets.__version__ >= '4.0'`` has broken websockets in ``sanic.__version__ <= '0.6.0'``, but it has been fixed in `master <https://github.com/channelcat/sanic/commit/bca1e084116335fd939c2ee226070f0428cd5de8>`_.

Tips
----

* `Blueprints Testing <https://github.com/yunstanford/pytest-sanic/issues/3>`_
* ``test_cli.ws_connect`` does not work in ``sanic.__version__ <= '0.5.4'``, because of a Sanic bug, but it has been fixed in master branch.
* `Importing app has loop already running <https://github.com/yunstanford/pytest-sanic/issues/1>`_ when you have `db_init` listeners.
* `Incorrect coverage report <https://github.com/pytest-dev/pytest-cov/issues/117>`_ with ``pytest-cov``, but we can have workarounds for this issue, it's a pytest loading plugin problem essentially.
* Websockets > 4.0 has broken websockets in ``sanic.__version__ <= '0.6.0'``, but it has been fixed in `master <https://github.com/channelcat/sanic/commit/bca1e084116335fd939c2ee226070f0428cd5de8>`_


Also, feel free to create issue if you have any question.
