单元测试参数化

（1）编写测试方法

http_requests.py

import requests

class HttpRequest:

    def http_request(self, url, data, method,headers = None):
        '''url:请求地址 http://xxxx:port
           param:传递的参数 非必填参数 字典的格式传递参数
           method:请求方式  支持get,post,put...
           cookie：请求的时候传递的cookie值
        '''

        if method.lower() == 'get':
            res = requests.get(url, data)
        elif method.lower() == 'post':
            res = requests.post(url, data, headers=headers)
        else:
            res = requests.patch(url, data, headers=headers)
        return res

(2)编写测试用例方法

test_http.py

import unittest
import json
from TestAuto.api_item.qingchengdai_Parameterization.http_request import HttpRequest
from TestAuto.api_item.qingchengdai_Parameterization.get_data import GetData



class TestHttp(unittest.TestCase):
    def setUp(self):
        pass

    def __init__(self,methodName,url,data,method,expected):  # 通过初始化函数来传参数
        super(TestHttp,self).__init__(methodName)  # 保留父类的方法
        self.url = url
        self.data = data
        self.method = method
        self.expected = expected

    def test_login_api(self):  # 登录
        # for item in test_data_login:
            res = HttpRequest().http_request(self.url, json.dumps(self.data), self.method,getattr(GetData,'headers'))
            try:
                self.assertEqual(self.expected,res.json()['code'])
            except AssertionError as e:
                print("test_login_api error is {}".format(e))
                raise e
            print(res.json())
    def test_recharge_api(self): # 充值(需要登录的均可使用改api)
        login_url = 'http://api.lemonban.com/futureloan/member/login'  # 登录地址
        test_data_login = {'mobile_phone': '18669019958', 'pwd': '12345678'}
        Auth_json = HttpRequest().http_request(login_url, json.dumps(test_data_login), 'POST',getattr(GetData, 'headers')).json()
        token = Auth_json['data']['token_info']['token']
        token_type = Auth_json['data']['token_info']['token_type']
        Authorization_value = token_type + ' ' + token
        getattr(GetData, 'headers')['Authorization'] = Authorization_value
        # for item1 in test_data_recharge:
        res = HttpRequest().http_request(self.url, json.dumps(self.data), self.method,
                                         getattr(GetData, 'headers'))
        try:
            self.assertEqual(self.expected,res.json()['code'])
        except AssertionError as e:
            print("test_login_api error is {}".format(e))
            raise e
        print(res.json())


    def tearDown(self):
        pass

请求头方法：

get_data.py

class GetData:
    headers = {'X-Lemonban-Media-Type': 'lemonban.v2', 'Content-Type': 'application/json; charset=UTF-8','Authorization':None}

(3)测试数据与生成测试报告

test_suite.py

import unittest
import time
from TestAuto.api_item.qingchengdai_Parameterization.test_http import TestHttp  # 类名
import HTMLTestRunner

login_url = 'http://api.lemonban.com/futureloan/member/login'# 登录地址
recharge_url = 'http://api.lemonban.com/futureloan/member/recharge'# 充值地址
test_data_login = [{'url':login_url,'data':{'mobile_phone': '18669019958', 'pwd': '12345678'},'method':'post','expected':0},
            {'url':login_url,'data':{'mobile_phone': '18669019958', 'pwd': '12345'},'method':'post', 'expected':1001}]
test_data_recharge = [{'url': recharge_url, 'data': {'member_id': '899710', 'amount': '1000'}, 'method': 'post',
                      'expected': 0},
                      {'url': recharge_url, 'data': {'member_id': '899711', 'amount': '1000'}, 'method': 'post',
                       'expected': 1007}]



suite = unittest.TestSuite()
for item in test_data_login:  # 创建登录实例
    suite.addTest(TestHttp('test_login_api',item['url'],item['data'],item['method'],item['expected']))  # 实例的方式加载用例
for item1 in test_data_login:  # 创建充值实例
    suite.addTest(TestHttp("test_recharge_api",item1['url'],item1['data'],item1['method'],item1['expected']))


with open('test_report_qingchengdai_Parameterization.html','wb') as file:
    runner = HTMLTestRunner.HTMLTestRunner(stream=file,
                                           verbosity=2,
                                           title= time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(time.time())) +'测试报告标题',
                                           description='测试报告描述' )

    runner.run(suite)

if'__name__' == '__main__':
    unittest.TestCase()
