ddt&Json&Requests&unittest-接口自动化测试实例

一、封装post/get方法

json.dumps() 将dict类型数据转化为str；
json.loads() 将str类型数据转化为dict；
json.dump()  将dict类型数据转化为str，并写入到json文件中；
json.load()  从json文件读取数据；

import requests
import json

class Leadscloud( ):

    def send_post(self, url, data, headers):
        response = requests.post(url=url, data=json.dumps(data), headers=headers).json()  		#是dict
        #response = requests.post(url=url, data=data, headers=headers),是200
        #json.dumps()将dict类型数据转化为str
        print(json.dumps(response, indent=4, sort_keys=True, ensure_ascii=False))
        return response

    def send_get(self, url, data, headers):
        response = requests.get(url=url, params=data, headers=headers).json()  #是dict
        # response = requests.get(url=url, params=data, headers=headers)       #是200
        #json.dumps()将dict类型数据转化为str
        print(json.dumps(response, indent=4, sort_keys=True, ensure_ascii=False))
        return response

    def run_main(self, url, data, headers, method):
        result = None
        if method == 'post':
            result = self.send_post(url, data, headers)
        elif method == 'get':
            result = self.send_get(url, data, headers)
        else:
            print("不是post方法，也不是get方法")
        return result

if __name__ == '__main__':
    url = " "
    headers = {"Content-Type": "application/json; charset=UTF-8"}
    parameter = {"visitorIdList": ["10110FK2019120214583914746", "10110FK2019111120131210678"]}
    result1 = Leadscloud().run_main(url, data=parameter, headers=headers, method='post')
    print(result1)

二、使用@ddt.file_data(‘文件路径’)实现数据驱动

@ddt ：修饰测试类
@data()：包含与要提供给测试的值一样多的参数。
@unpack：当传递的参数是复杂的数据结构时使用。如使用元组或者列表，添加unpack之后，它将自动将元组和列表解压缩为多个参数，并将字典解压缩为多个关键字参数。
@file_data('文件路径')：读取json（yaml）文件数据。

import unittest
import ddt
from leadscloud_common.common_method import Leadscloud

@ddt.ddt
class TestLogin(unittest.TestCase):

    @ddt.file_data('E:\\interface\\leadscloud_test_data\\login_again.json')
    def testLoginInterface(self, url, data, headers, method):
         '''取json文件的 url, data, headers, method四个参数'''
         data = Leadscloud().run_main(url, data, headers, method)
         assert  data.status_code == 200
         # data.raise_for_status()

if __name__ == '__main__':
    unittest.main(verbosity=2)

使用@ddt.data和@ddt.unpack

    @ddt.data([{"123": ["123"]}], [{"hhhh": ["yyyy"]}])
    @ddt.unpack
    def test_visitorIdList_isNull(self, data):
        try:
            data = Leadscloud().run_main(url=self.url, data=data, headers=self.headers, method='post')
            assert data['message'] == '参数不能为空'
        except Exception as e:
            raise e

    @ddt.data([{"visitorIdList": 1}], [{"visitorIdList": 'abc'}], [{"visitorIdList": True}])
    @ddt.unpack
    def test_visitorIdList_isError(self, data):
        try:
            data = Leadscloud().run_main(url=self.url, data=data, headers=self.headers, method='post')
            assert data['message'] == '参数格式有误'
        except Exception as e:
            raise e

requests.post(url='', files={'file': open('test.xls', 'rb')}, headers={'Content-Type': 'binary'})
requests.get(url='', params={'key1': 'value1', 'key2': 'value2'}, headers=headers)
requests.post(url='', data={'key1': 'value1', 'key2': 'value2'}, headers=headers)
**requests.post(url='', json={{'key1': 'value1', 'key2': 'value2'}}, headers=headers) (传入json格式文件)**
requests.post(url='', data=json.dumps({'key1': 'value1', 'key2': 'value2'}), headers=headers)（传入json格式文件）

三、json文件
test1及test2为两个测试用例；url,data,headers,method为四个参数

{
   "test1": {"url": url1,
          "data": {"userName": "[email protected]", "password": "212abddsfsdf"},
          "headers": {"Content-Type": "application/x-www-form-urlencoded; charset=UTF-8"},
          "method": "post"
        },
   "test2": {"url": url2,
         "data": {"userName": "liyali_10110", "password": "222"},
          "headers": {"Content-Type": "application/x-www-form-urlencoded; charset=UTF-8"},
         "method": "post"
        }
}
