我想测试对我不拥有的 api 的 http 调用（集成测试）。我创建了一个带有异步函数的类，该函数使用 aiohttp 进行 http 调用。然后我做了一个测试用例来运行这个函数并断言它的状态。

测试/test_coinbase.py：

import json
import os
from aiohttp.test_utils import AioHTTPTestCase, unittest_run_loop

from src.coinbase import CoinbaseService

class CoinbaseTestCase():

    async def test_get_current_user(self):

        coinbase_service = CoinbaseService(os.getenv('COINBASE_APIURL'), os.getenv('COINBASE_APIKEY'), os.getenv('COINBASE_APISECRET'))

        status, user = await coinbase_service.show_current_user()

        assert status == 200

src/coinbase.py：

import json, hmac, hashlib, time
import aiohttp


class CoinbaseService:

    def __init__(self, API_URL, API_KEY, API_SECRET):
        self.API_URL = API_URL
        self.API_KEY = API_KEY
        self.API_SECRET = API_SECRET


    def generateHeaders(self, method, path_url, body = ''):
        timestamp = str(int(time.time()))
        message = timestamp + method + path_url + body
        signature = hmac.new(self.API_SECRET, message, hashlib.sha256).hexdigest()

        headers = {
            'CB-ACCESS-SIGN': signature,
            'CB-ACCESS-TIMESTAMP': timestamp,
            'CB-ACCESS-KEY': self.API_KEY
        }

        return headers

    async def show_current_user(self):

        path_url = 'user'

        headers = self.generateHeaders('GET', path_url)

        async with aiohttp.ClientSession() as session:
            async with session.get(path_url, headers=headers) as response:
                status = response.status
                user = await response.json()
                return status, user

当我在我的根项目中运行以下命令时，我得到以下信息。

  1. CoinbaseTestCase与默认命名规则不匹配pytest被视为测试类，请参阅Python 测试发现的约定。要么将类重命名为类似的名称TestCoinbase，要么定义您自己的命名约定。

  2. vanillapytest不支持运行异步测试。安装pytest-asyncio：

    $ pip install pytest-asyncio

    并用标记标记异步测试asyncio：

    class TestCoinbase:

    @pytest.mark.asyncio
    async def test_get_current_user(self):
        await coinbase_service.show_current_user()
        ...
