問題描述

我正在編寫一個使用 Kenneth Reitz 的 requests library 執(zhí)行 REST 操作的應(yīng)用程序，我正在努力尋找對這些應(yīng)用程序進行單元測試的好方法，因為 requests 通過模塊級方法提供其方法.

I am writing an application that performs REST operations using Kenneth Reitz's requests library and I'm struggling to find a nice way to unit test these applications, because requests provides its methods via module-level methods.

我想要的是合成雙方對話的能力；提供一系列請求斷言和響應(yīng).

What I want is the ability to synthesize the conversation between the two sides; provide a series of request assertions and responses.

推薦答案

實際上有點奇怪的是，這個庫有一個關(guān)于最終用戶單元測試的空白頁面，同時目標(biāo)是用戶友好性和易用性.然而，Dropbox 有一個易于使用的庫，不出所料地稱為 responses.這是它的介紹帖.它說他們沒有使用 httpretty，同時聲明沒有失敗的原因，寫了一個類似API的庫.

It is in fact a little strange that the library has a blank page about end-user unit testing, while targeting user-friendliness and ease of use. There's however an easy-to-use library by Dropbox, unsurprisingly called responses. Here is its intro post. It says they've failed to employ httpretty, while stating no reason of the fail, and written a library with similar API.

import unittest

import requests
import responses


class TestCase(unittest.TestCase):

  @responses.activate  
  def testExample(self):
    responses.add(**{
      'method'         : responses.GET,
      'url'            : 'http://example.com/api/123',
      'body'           : '{"error": "reason"}',
      'status'         : 404,
      'content_type'   : 'application/json',
      'adding_headers' : {'X-Foo': 'Bar'}
    })

    response = requests.get('http://example.com/api/123')

    self.assertEqual({'error': 'reason'}, response.json())
    self.assertEqual(404, response.status_code)
