契约：尝试设置模拟提供程序时出错

问题描述

我正在尝试使用 pytest 编写我的第一个Pact-python测试，有人可以告诉我我的代码有什么问题吗？

enter code here    

 Blog.ImageIndex = "images.jpg";
                    if (Blog != null)
                    {
                        Blog.ImageIndex = Guid.NewGuid().ToString() + Path.GetExtension(imageblog.FileName);
                        imageblog.SaveAs(Server.MapPath("/Images/Productimages/" + Blog.ImageIndex));
                        ImageResizer img = new ImageResizer();
                        img.Resize(Server.MapPath("/Images/Productimages/" + Blog.ImageIndex),Server.MapPath("/Images/Productimages/Thumb/" + Blog.ImageIndex));
                    }

stacktrace 中的错误：

AttributeError：模块“ pact”没有属性“ Like”

解决方法

能否请您确认您使用的是https://github.com/pact-foundation/pact-python/中的pact-python（而不是pactman，这不是Pact Foundation维护的项目）？

这可能与您设置测试的方式有关？

这是一个示例项目，您可以参考：https://github.com/pactflow/example-consumer-python/

相关测试代码：

"""pact test for product service client"""

import json
import logging
import os
import requests
from requests.auth import HTTPBasicAuth

import pytest
from pact import Consumer,Like,Provider,Term,Format

from src.consumer import ProductConsumer

log = logging.getLogger(__name__)
logging.basicConfig(level=logging.INFO)
print(Format().__dict__)

PACT_MOCK_HOST = 'localhost'
PACT_MOCK_PORT = 1234
PACT_DIR = os.path.dirname(os.path.realpath(__file__))


@pytest.fixture
def consumer():
    return ProductConsumer(
        'http://{host}:{port}'
        .format(host=PACT_MOCK_HOST,port=PACT_MOCK_PORT)
    )


@pytest.fixture(scope='session')
def pact(request):
    pact = Consumer('pactflow-example-consumer-python').has_pact_with(
        Provider('pactflow-example-provider-python'),host_name=PACT_MOCK_HOST,port=PACT_MOCK_PORT,pact_dir="./pacts",log_dir="./logs")
    try:
        print('start service')
        pact.start_service()
        yield pact
    finally:
        print('stop service')
        pact.stop_service()

def test_get_product(pact,consumer):
    expected = {
        'id': "27",'name': 'Margharita','type': 'Pizza'
    }

    (pact
     .given('a product with ID 10 exists')
     .upon_receiving('a request to get a product')
     .with_request('GET','/product/10')
     .will_respond_with(200,body=Like(expected)))

    with pact:
        user = consumer.get_product('10')
        assert user.name == 'Margharita'
