pytest plugin for aiohttp support

pytest-aiohttp

pytest plugin for aiohttp support

The library provides useful fixtures for creation test aiohttp server and client.

Installation

$ pip install pytest-aiohttp

Add asyncio_mode = auto line to pytest configuration (see pytest-asyncio modes for details). The plugin works with strict mode also.

Usage

Write tests in pytest-asyncio style using provided fixtures for aiohttp test server and client creation. The plugin provides resources cleanup out-of-the-box.

The simple usage example:

from aiohttp import web


async def hello(request):
    return web.Response(body=b"Hello, world")


def create_app():
    app = web.Application()
    app.router.add_route("GET", "/", hello)
    return app


async def test_hello(aiohttp_client):
    client = await aiohttp_client(create_app())
    resp = await client.get("/")
    assert resp.status == 200
    text = await resp.text()
    assert "Hello, world" in text

See aiohttp documentation <https://docs.aiohttp.org/en/stable/testing.html#pytest> for more details about fixtures usage.

pytest-aiohttp's Issues

Support for asynchronous `create_app()` function in the fixture

Long story short

For now, if function create_app is asynchronous, then it's not possible to use it for initialize aiohttp_client.

Code:

# app.py
async def create_app() -> web.Application:
    app = web.Application()
    await setup_app(app)
    return app

# conftest.py
@pytest.fixture(scope='function')
async def rest_client(aiohttp_client):
    from app import create_app
    client = await aiohttp_client(create_app)
    yield client

# test_app.py
@pytest.mark.asyncio
async def test_app(rest_client: TestClient):
    resp: Response = await rest_client.get('/')
    assert resp.status == 200

Traceback:

    def wrapper(*args, **kwargs):
        loop = kwargs['event_loop']
        request = kwargs['request']
        if strip_event_loop:
            del kwargs['event_loop']
        if strip_request:
            del kwargs['request']
    
        gen_obj = f(*args, **kwargs)
    
        async def setup():
            res = await gen_obj.__anext__()
            return res
    
        def finalizer():
            """Yield again, to finalize."""
            async def async_finalizer():
                try:
                    await gen_obj.__anext__()
                except StopAsyncIteration:
                    pass
                else:
                    msg = "Async generator fixture didn't stop."
                    msg += "Yield only once."
                    raise ValueError(msg)

Expected behaviour

If create_app declared as asynchronous function, then aiohttp_client fixture is initialized with this function as usual.

Actual behaviour

ValueError: Unknown argument type: <class 'coroutine'> raises.

README should talk about avoiding _explicit_ loading pytest module

Hi,

Currently, README.rst describes that this module alows use of pytest module "without implicitly loading it".

Seems to me you are using meant to say explicitly in that sentence (i.e. that it loads pytest module automatically without needing to state it explicitly).

chardet can't be replaced by cchardet

Hi,

I removed chardet library and used cchardet to replace it.
Then I run unit test and got the error
TypeError: test_hello() missing 2 required positional arguments: 'test_client' and 'loop'

The test code is from website documentation.

# -*- coding: utf-8 -*-
from aiohttp import web

async def hello(request):
    return web.Response(text='Hello, world')

async def test_hello(test_client, loop):
    app = web.Application(loop=loop)
    app.router.add_get('/', hello)
    client = await test_client(app)
    resp = await client.get('/')
    assert resp.status == 200
    text = await resp.text()
    assert 'Hello, world' in text

I'm not sure it's cchardet problem or not. 😞

Thank you.

Compatibility with Python3.8 + Windows

I'm getting this error using the aiohttp_server fixture

self = <ProactorEventLoop running=False closed=True debug=False>
sock = <socket.socket fd=1496, family=AddressFamily.AF_INET, type=SocketKind.SOCK_STREAM, proto=0, laddr=('127.0.0.1', 50202)>

    def _stop_serving(self, sock):
        future = self._accept_futures.pop(sock.fileno(), None)
        if future:
            future.cancel()
>       self._proactor._stop_serving(sock)
E       AttributeError: 'NoneType' object has no attribute '_stop_serving'

The complete error log in https://dev.azure.com/johander-182/aiosonic/_build/results?buildId=281&view=logs&jobId=725faacd-bdc4-550c-e77e-408d4e6e9756&j=725faacd-bdc4-550c-e77e-408d4e6e9756&t=e856c400-4037-5c54-1baa-9af2a6ffb100

It works ok with windows and mac

The example uses deprecated `loop` parameter of web.Application

The example in the README calls web.Application(loop=loop), which is deprecated since aiohttp 3.5.

Follow PEP 561 to support type checking with mypy

Tests using pytest-aiohttp cannot be completely typechecked using mypy because it lacks the py.typed marker file and no separate stubs exist in PyPI.

This page details how a package can be made PEP 561 compatible, allowing mypy to check its usages: https://mypy.readthedocs.io/en/stable/installed_packages.html#creating-pep-561-compatible-packages

pytest-aiohttp is incompatible with pytest-asyncio v0.14.0

When running pytest-aiohttp with pytest-asyncio v0.14.0 I am seeing the following error:

RuntimeError: Timeout context manager should be used inside a task

This is related to a change in pytest-asyncio concerning event loop handling (see pytest-dev/pytest-asyncio#170). Explanation in pytest-dev/pytest-asyncio#170 (comment)

Would it be possible to coordinate with the pytest-asyncio team so both your awesome libraries can be used at the same time.

how to set the port to which web server listen

https://github.com/aio-libs/pytest-aiohttp

I did a little bit modified as follows:

import pytest
import json
import asyncio
import aiohttp
import requests
from aiohttp import web

routes = web.RouteTableDef()
print("\nroutes = {}".format(routes))


@routes.get('/notify/hello/{id}')
async def hello(request):
    print("post notify = {}".format(request))
    return web.Response(body=b'Hello, world')

def create_app(loop):
    app = web.Application(loop=loop)
    app.router.add_route('GET', '/', hello)
    return app

async def test_hello(test_client):
    client = await test_client(create_app)
    while True:
        pass
        # print("server running")

    resp = await client.get('/')
    assert resp.status == 200
    text = await resp.text()
    assert 'Hello, world' in text

I want to ensure server running continuously.

Created client hello to test server as follows:

import pytest
import json
import asyncio
import aiohttp
import requests
from aiohttp import web


SERVER_IP = "127.0.0.1"
SERVER_PORT= "80"

DEFAULT_HTTP_PATH='http://'+SERVER_IP+':'+SERVER_PORT

msg_path = {
    6: '/notify/hello/1111',

}

GET = "get"
def test_get_hello_1111():
    path = DEFAULT_HTTP_PATH + msg_path[6]

    async def method():
        resp = await aiohttp.ClientSession().request(
            GET, path)

        print('Response Info -----')
        print(str(resp))
        print('Response Body -----')
        print(await resp.text())
        assert 200 == resp.status
    asyncio.get_event_loop().run_until_complete(method())

aiohttp.client_exceptions.ClientConnectorError: Cannot connect to host 127.0.0.1:80 ssl:False [Connect call failed ('127.0.0.1', 80)]

I tried port number 8080, same failure Connect call failed ('127.0.0.1', 8080).

How to set the port in the sample program?
How to find the port web server is listening to?

fix by masking loop fixture

To fix this problem (still using pytest-asyncio plugin), one has to uncomment the loop fixture.

Improve README

Since pytest-aiohttp now is the host of provided fixtures, their documentation should be moved out from aiohttp itself and placed into README.rst. The aiohttp doc can contain a simple usage example and a link to README for future reading.

Initial Update

Hi 👊

This is my first visit to this fine repo, but it seems you have been working hard to keep all dependencies updated so far.

Once you have closed this issue, I'll create seperate pull requests for every update as soon as I find one.

That's it for now!

Happy merging! 🤖

This issue is related to aiohttp#2880.

pytest-aiohttp freezes when using `asyncio.create_subprocess_exec` in a process that reads from stdin

Problem description

When running a test suite with pytest-aiohttp and aiohttp>3.0 the test suite hangs when calling Process.communicate passing an input parameter in a process spawned by asyncio.create_subprocess_exec (that has a pipe in stdin) the second time a test is ran (the issue does not present if only one test is ran - disregarding the order or which set of tests are selected).

How to reproduce

Installed packages:

aiohttp==3.4.4
async-timeout==3.0.1
atomicwrites==1.2.1
attrs==18.2.0
chardet==3.0.4
idna==2.7
more-itertools==4.3.0
multidict==4.4.2
pluggy==0.8.0
py==1.7.0
pytest==3.9.2
pytest-aiohttp==0.3.0
six==1.11.0
yarl==1.2.6

Create a file called test.py with this code

import asyncio

async def test_1():
    process = await asyncio.create_subprocess_exec(
            "cat",
            stderr=asyncio.subprocess.PIPE,
            stdin=asyncio.subprocess.PIPE,
            stdout=asyncio.subprocess.PIPE
            )
    stdout, stderr = await process.communicate(input="asyncio rules".encode())

    assert stdout == b"asyncio rules"

async def test_2():
    process = await asyncio.create_subprocess_exec(
            "cat",
            stderr=asyncio.subprocess.PIPE,
            stdin=asyncio.subprocess.PIPE,
            stdout=asyncio.subprocess.PIPE
            )
    stdout, stderr = await process.communicate(input="asyncio rules".encode())

    assert stdout == b"asyncio rules"

and then run python -m pytest test.py. The interpreter hangs when running the second test.

Reproducer systems

I was able to reproduce this issue in MacOs and Linux:

asyncio_mode deprecation warning is emitted for test suites that don't use aiohttp at all

When pytest-aiohttp plugin is installed, practically every single test suite on my system emits the following deprecation warning:

========================================================== warnings summary ===========================================================
../../../../../../../../usr/lib/python3.8/site-packages/pytest_aiohttp/plugin.py:28
  /usr/lib/python3.8/site-packages/pytest_aiohttp/plugin.py:28: DeprecationWarning: The 'asyncio_mode' is 'legacy', switching to 'auto'
 for the sake of pytest-aiohttp backward compatibility. Please explicitly use 'asyncio_mode=strict' or 'asyncio_mode=auto' in pytest co
nfiguration file.
    config.issue_config_time_warning(LEGACY_MODE, stacklevel=2)

-- Docs: https://docs.pytest.org/en/stable/how-to/capture-warnings.html

In the best case, this is meaningless since the vast majority of these packages don't use aiohttp at all, and therefore shouldn't be setting asyncio_mode in the first place. In the worst, it causes test failures for various packages that expect specific pytest output, in particular pytest plugins.

Example code does not execute

The example code listed on the PyPi page does not run, with multiple errors occurring.

The first is an incorrect await infront of create_app. This has already been fixed in master branch.

Second is DeprecationWarning: The object should be created within an async function with this callstack:

Adding this code to catch the deprecation warnings:

Still results in another exception:

Setup GitHub test workflow

A champion is wanted!

The project has tests but I had no time for setting up the GitHub integration.

every test run twice: pyloop and uvloop

hello! help me, please

my aiohttp application works with uvloop
asyncio.set_event_loop_policy(uvloop.EventLoopPolicy())
loop = asyncio.get_event_loop()

surprisingly every pytest test runs twice: with uvloop and pyloop

@fixture
def client(loop, test_client):
    app = init_app(loop)
    return loop.run_until_complete(test_client(app))

async def test_get(client):
    response = await client.get('v1/accounts/{}'.format(ACCOUNT_ID))
    assert response.status == 200

why?

Tests fail to run with pytest-asyncio==0.18 and asyncio_mode=strict

Prerequisite: Install pytest-asyncio==0.18.0

pytest-aiohttp fails to run tests when the flag asyncio_mode is set to strict in setup.cfg.
Full trace:

E    +    where <function aiohttp_client at 0x112fa5940> = <FixtureDef argname='aiohttp_client' scope='function' baseid=''>.func

Setting the flag asyncio_mode=auto is a functional workaround.

can't use context vars in shutdown

The following test passes but then errors in the finalizers when it tries to run the app shutdown, as the context is no longer available:

from contextvars import ContextVar

import pytest
from aiohttp import web

CV = ContextVar("CV")


async def startup(_app):
    CV.set(1)


async def shutdown(app):
    assert CV.get() == 1


async def handler(request):
    return web.Response(body=str(CV.get()))


@pytest.fixture
def app():
    app = web.Application()
    app.on_startup.append(startup)
    app.on_shutdown.append(shutdown)
    app.add_routes([web.get("/", handler)])
    return app


@pytest.fixture
def client(app, loop, aiohttp_client):
    return loop.run_until_complete(aiohttp_client(app))


async def test_get(client):
    response = await client.get("/")
    assert await response.content.read() == b"1"
