python_自动化测试用例参数化

参数化有三种，代码驱动，数据驱动，关键字驱动

代码驱动，测试数据写在代码中 如下：

import requests,json
import unittest
import BeautifulReport
fido_url = 'http://192.168.6.162:8080/uaf/reg/receive'
'''代码驱动，代码实现做参数化的例子'''
reg_receive_data1 = {
    "context": {
        "appID":"",
        "transNo":"",
        "userName":"mh",
        "transType":"",
        "authType":"",
        "opType":"",
        "devices":{"deviceName": "HUA WEI", "deviceType": "iPhone 7", "deviceID": ""}
    }
}
reg_receive_data2 = {
    "context": {
        "appID":"",
        "transNo":"",
        "userName":"mh",
        "transType":"",
        "authType":"",
        "opType":"",
        "devices":{"deviceName": "HUA WEI", "deviceType": "iPhone 7", "deviceID": ""}
    }
}
headers = {
"Connection": "keep-alive",
"Content-Type": "application/json",
"Content-Length": "",
"Host": "192.168.6.162:8080",
"User-Agent": "Apache-HttpClient/4.2.6 (java 1.5)"
}
def fido_reg(url,data,headers):
    r = requests.post(url=url,data=json.dumps(data),headers=headers).json()
    return r
print(fido_reg(fido_url,reg_receive_data1,headers))#正常的返回
class Reg_receive(unittest.TestCase):
    def test(self):
        '''请求正常'''
        result = fido_reg(fido_url,reg_receive_data1,headers)
        self.assertEqual(1200,result.get('statusCode'))
        self.assertEqual('OK',result.get('description'))
    def test_02(self):
        '''appid为空'''
        result = fido_reg(fido_url,reg_receive_data2,headers)
        self.assertEqual(1401,result.get('statusCode'))
        self.assertEqual('Parameter- appID is EMPTY',result.get('description'))

bf = BeautifulReport.BeautifulReport(unittest.makeSuite(Reg_receive))
bf.report(filename='测试报告1',description='接口测试报告')

数据驱动，代码读取excel，或txt

import xlrd
import requests
import unittest
import BeautifulReport as bf
import time
import parameterized
import json
path = 'testcase_adapter.xlsx'#定义测试用例名字
testreport = time.strftime('%Y%m%d',time.localtime())#定义测试报告名字
class Op_excel:
    def r_excel(self,path):
        r_workbook = xlrd.open_workbook(path)
        r_sheet = r_workbook.sheets()[0]
        return r_sheet,r_workbook
    #读excel

    def get_nrows(self,r_sheet):
        nrows = r_sheet.nrows
        return nrows

e = Op_excel()#实例化一个操作excel的类的对象
newsheet = e.r_excel(path)[0]#对象调用类的操作读excel方法返回操作的sheet给newsheet
newnrows = e.get_nrows(newsheet)#对象调用类返回行数nrow给newrows
testdata = []
for i in range(1,newnrows):#循环读取excel中的测试用例，把用例加到testdata中生成二维数组
        testdata.append(newsheet.row_values(i))

def reg_receive(url,data,headers):#定义发送的post请求
    r = requests.post(url=url,data=json.dumps(data),headers=headers).json()
    return r

class Test_case(unittest.TestCase):
    @classmethod #类函数，执行测试用例开始前执行
    def setUpClass(cls):
        print('接口测试开始')

    @classmethod #类函数，执行测试用例结束后候执行
    def tearDownClass(cls):
        print('接口测试结束')

    @parameterized.parameterized.expand(testdata)#testdata是存的excel中的测试case
    def test_reg_receive(self,url,data,headers,expect,desc):
        '''测试用例'''
        self._testMethodName=desc#desc是对用例的描述
        result = reg_receive(url,json.loads(data),json.loads(headers))
        statuscode = result['statusCode']#返回状态码
        self.assertEqual(int(expect),statuscode)#与测试用例中的状态码进行比对

# unittest.main()
bf = bf.BeautifulReport(unittest.makeSuite(Test_case))
bf.report(filename=testreport,description='接口测试报告')
