python unittest做api自動化測試

專案測試對於一個專案的重要性,大家應該都知道吧。
寫python的朋友,應該都寫過自動化測試指令碼。
最近正好負責公司專案中的api測試,
下面寫了一個簡單的例子,對API 測試進行梳理。

首先,編寫restful api介面檔案 testpost.py,包含了get,post,put方法

#!/usr/bin/env python
# -*- coding: utf-8 -*-
from flask import request
from flask_restful import Resource
from flask_restful import reqparse


test_praser = reqparse.RequestParser()
test_praser.add_argument('ddos'
) class TestPost(Resource): def post(self, PostData): data = request.get_json() user = User('wangjing') if data['ddos']: return {'hello': 'uese', "PostData": PostData, 'ddos': 'data[\'ddos\']'} return {'hello': 'uese', "PostData": PostData} def get
(self, PostData):
data = request.args if data and data['ddos']: return "hello" + PostData + data['ddos'], 200 return {'hello': 'uese', "PostData": PostData} def put(self, PostData): data = test_praser.parse_args() if data and data['ddos']: return
"hello" + PostData + data['ddos'], 200 return {'hello': 'uese', "PostData": PostData}

ps:對於request的取值,我這裡定義了常用的三種方法:

post方法:request.get_json(),在呼叫API時,傳值是json方式

get和put方法:request.args 或者reqparse.RequestParser(),呼叫API時,傳的是字串

其次,定義Blueprint(藍圖)檔案 init.py

#!/usr/bin/env python
    # -*- coding: utf-8 -*-
    from flask import Blueprint
    from flask_restful import Api
    from testpost import TestPost

    testPostb = Blueprint('testPostb', __name__)
    api = Api(testPostb)
    api.add_resource(TestPost, '/<string:PostData>/postMeth')

然後,編寫測試指令碼testPostM.py

#!/usr/bin/env python
    # -*- coding: utf-8 -*-
    import unittest
    import json
    from secautoApp.api.testPostMeth import api
    from flask import url_for
    from run import app
    from secautoApp.api.testPostMeth import TestPost

    headers = {'Accept': 'application/json',
               'Content-Type': 'application/json'
               }

    class APITestCase(unittest.TestCase):
        def setUp(self):
            # self.app = create_app(os.getenv("SECAUTOCFG") or 'default')
            self.app = app
            #     self.app_context = self.app.app_context()
            #     self.app_context.push()
            self.client = self.app.test_client()

        #
        # def tearDown(self):
        #     self.app_context.pop()

        def test_post(self):
            # with app.test_request_context():

            response = self.client.get(api.url_for(TestPost, PostData='adb', ddos='123'))
            self.assertTrue(response.status_code == 200)

            response = self.client.get(url_for('testPostb.testpost', PostData='adb', ddos='123'))
            self.assertTrue(response.status_code == 200)    
            self.assertTrue(json.loads(response.data)['PostData'] =='adb')

            response = self.client.post(url_for('testPostb.testpost', PostData='adb'), headers=headers,
                                        data=json.dumps({"ddos": '123'}))
            print json.loads(response.data)
            self.assertTrue(response.status_code == 200)

            response = self.client.put(url_for('testPostb.testpost', PostData='adb', ddos='123'))
            self.assertTrue(json.loads(response.data) == 'helloadb123')

            response = self.client.put(url_for('testPostb.testpost', PostData='adb'))
            print json.loads(response.data)['PostData']
            self.assertTrue(response.status_code == 200)

ps:呼叫的api url 主要用的是flask_restful 的api.url_for,或者是flask的url_for,下面我來說下這2種方法的具體使用

flask_restful 的api.url_for說明

api.url_for(TestPost,PostData=’adb’),這裡的TestPost指的是restful api介面檔案中定義的class,因為我們在api藍圖中,已經通過api.add_resource(TestPost, ‘//postMeth’)新增類的方式定義過

flask的url_for的使用說明

url_for(‘testPostb.testpost’, PostData=’adb’, ddos=’123’),’testPostb.testpost’這個字串中

testPostb指的是藍圖的名稱,也就是testPostb = Blueprint(‘testPostb’, name)中Blueprint(‘testPostb’,name)中的testPostb。

testpost指的是藍圖下endpoit的端點名稱,flask_restful中,指的是api.add_resource(TestPost, ‘//postMeth’)中 類名TestPost的小寫

啟動測試指令碼:

    C:\secauto3>python run.py test
    test_post (testPostM.APITestCase) ... ok

    ----------------------------------------------------------------------
    Ran 1 test in 0.056s

    OK

小總結:url_for的傳值和request中的取值是有對應關係的,最後就是flask_restful中端點的方式,一定要是api.add_resource中類名的小寫
