如何删除 pytest 的重复响应？

Question

响应库为请求提供模拟。在我的例子中，它看起来通常是这样的：

import responses

@responses.activate
def test_foo():
    # Add mocks for service A
    responses.add(responses.POST, 'http://service-A/foo', json={'bar': 'baz'}, status=200)
    responses.add(responses.POST, 'http://service-A/abc', json={'de': 'fg'}, status=200)


@responses.activate
def test_another_foo():
    # Add mocks for service A
    responses.add(responses.POST, 'http://service-A/foo', json={'bar': 'baz'}, status=200)
    responses.add(responses.POST, 'http://service-A/abc', json={'de': 'fg'}, status=200)

如何避免代码重复？

我希望有一个 mock_service_a 固定装置或类似的东西。

正如您所建议的，创建夹具可以解决这些问题。

import pytest
import responses
import requests

@pytest.fixture(scope="module", autouse=True)
def mocked_responses():
    with responses.RequestsMock() as rsps:
        rsps.add(
            responses.POST, "http://service-a/foo", json={"bar": "baz"}, status=200
        )
        rsps.add(
            responses.POST, "http://service-a/abc", json={"de": "fg"}, status=200
        )
        yield rsps


def test_foo():
    resp = requests.post("http://service-a/foo", json={"bar": "baz"})
    assert resp.status_code == 200


def test_another_foo():
    resp = requests.post("http://service-a/abc", json={"de": "fg"})
    assert resp.status_code == 200

运行它returns:

How can I de-duplicate responses for pytest?
