Python+requests+unittest+excel搭建接口自动化测试框架

一、框架结构

工程目录【文末有配套视频和资料免费领取】

代码：基于python2编写

二、Case文件设计

三、基础包 base

3.1 封装get/post请求（runmethon.py）

import requests
import json
class RunMethod:
    def post_main(self,url,data,header=None):
        res = None
        if header !=None:
            res = requests.post(url=url,data=data,headers=header)
        else:
            res = requests.post(url=url,data=data)
        return res.json()
 
    def get_main(self,url,data=None,header=None):
        res = None
        if header !=None:
            res = requests.get(url=url,data=data,headers=header,verify=False)
        else:
            res = requests.get(url=url,data=data,verify=False)
        return res.json()
 
    def run_main(self,method,url,data=None,header=None):
        res = None
        if method == 'Post':
            res = self.post_main(url,data,header)
        else:
            res = self.get_main(url,data,header)
        return json.dumps(res,ensure_ascii=False,sort_keys=True,indent=2)

3.2 封装mock（mock.py）

from mock import mock
#模拟mock 封装
def mock_test(mock_method,request_data,url,method,response_data):
    mock_method = mock.Mock(return_value=response_data)
    res = mock_method(url,method,request_data)
    return res

四、数据操作包 operation_data

4.1 获取excel单元格中的内容（get_data.py）

#coding:utf-8
from tool.operation_excel import OperationExcel
import data_config
from tool.operation_json import OperetionJson
from tool.connect_db import OperationMysql
class GetData:
    def __init__(self):
        self.opera_excel = OperationExcel()
 
    #去获取excel行数,就是case的个数
    def get_case_lines(self):
        return self.opera_excel.get_lines()
 
    #获取是否执行
    def get_is_run(self,row):
        flag = None
        col = int(data_config.get_run())

        if run_model == 'yes':
            flag = True
        else:
            flag = False
        return flag
 
    #是否携带header
    def is_header(self,row):
        col = int(data_config.get_header())
        header = self.opera_excel.get_cell_value(row,col)
        if header != '':
            return header
        else:
            return None
    #获取请求方式
    def get_request_method(self,row):
        col = int(data_config.get_run_way())

        return request_method
 
    #获取url
    def get_request_url(self,row):
        col = int(data_config.get_url())
        url = self.opera_excel.get_cell_value(row,col)
        return url
 
    #获取请求数据
    def get_request_data(self,row):
        col = int(data_config.get_data())
        data = self.opera_excel.get_cell_value(row,col)
        if data == '':
            return None
        return data
 
    #通过获取关键字拿到data数据
    def get_data_for_json(self,row):
        opera_json = OperetionJson()
        request_data = opera_json.get_data(self.get_request_data(row))
        return request_data
 
    #获取预期结果
    def get_expcet_data(self,row):
        col = int(data_config.get_expect())
        expect = self.opera_excel.get_cell_value(row,col)
        if expect == '':
            return None
        return expect
 
    #通过sql获取预期结果
    def get_expcet_data_for_mysql(self,row):
        op_mysql = OperationMysql()
        sql = self.get_expcet_data(row)
        res = op_mysql.search_one(sql)
        return res.decode('unicode-escape')
 
    def write_result(self,row,value):
        col = int(data_config.get_result())
        self.opera_excel.write_value(row,col,value)
 
    #获取依赖数据的key
    def get_depend_key(self,row):
        col = int(data_config.get_data_depend())
        depent_key = self.opera_excel.get_cell_value(row,col)
        if depent_key == "":
            return None
        else:
            return depent_key
 
    #判断是否有case依赖
    def is_depend(self,row):
        col = int(data_config.get_case_depend())
        depend_case_id = self.opera_excel.get_cell_value(row,col)
        if depend_case_id == "":
            return None
        else:
            return depend_case_id
 
    #获取数据依赖字段
    def get_depend_field(self,row):
        col = int(data_config.get_field_depend())
        data = self.opera_excel.get_cell_value(row,col)
        if data == "":
            return None
        else:
            return data

4.2 获取excel中每个列（data_config.py）

#coding:utf-8
class global_var:
    #case_id
    Id = '0'
    request_name = '1'
    url = '2'
    run = '3'
    request_way = '4'
    header = '5'
    case_depend = '6'
    data_depend = '7'
    field_depend = '8'
    data = '9'
    expect = '10'
    result = '11'
#获取caseid
def get_id():
    return global_var.Id
 
#获取url
def get_url():
    return global_var.url
 
def get_run():
    return global_var.run
 
def get_run_way():
    return global_var.request_way
 
def get_header():

def get_data():
    return global_var.data
 
def get_expect():
    return global_var.expect
 
def get_result():
    return global_var.result
 
def get_header_value():
    return global_var.header

4.3 解决数据依赖（dependent.py ）

#coding:utf-8
import sys
import json
sys.path.append('C:/Users/lxz/Desktop/InterFace_JIA')
from tool.operation_excel import OperationExcel
from base.runmethod import RunMethod
from operation_data.get_data import GetData

#coding:utf-8
import xlrd
from xlutils.copy import copy
class OperationExcel:
    def __init__(self,file_name=None,sheet_id=None):
        if file_name:
            self.file_name = file_name
            self.sheet_id = sheet_id    
        else:
            self.file_name = '../dataconfig/case1.xls'
            self.sheet_id = 0
        self.data = self.get_data()
 
    #获取sheets的内容
    def get_data(self):

        tables = data.sheets()[self.sheet_id]
        return tables
 
    #获取单元格的行数
    def get_lines(self):
        tables = self.data

        write_data = copy(read_data)
        sheet_data = write_data.get_sheet(0)
        sheet_data.write(row,col,value)
        write_data.save(self.file_name)
 
    #根据对应的caseid 找到对应行的内容
    def get_rows_data(self,case_id):
        row_num = self.get_row_num(case_id)

        row_data = tables.row_values(row)
        return row_data
 
    #获取某一列的内容
    def get_cols_data(self,col_id=None):
        if col_id != None:

            str_one = str_one.encode('unicode-escape').decode('string_escape')
        return cmp(str_one,str_two)
        if str_one in str_two:
            flag = True
        else:
            flag = False
        return flag
 
 
    def is_equal_dict(self,dict_one,dict_two):
        '''
        判断两个字典是否相等
        '''
        if isinstance(dict_one,str):
            dict_one = json.loads(dict_one)

class OperationHeader:
 
    def __init__(self ,response):
        self.response = json.loads(response)
 
    def get_response_url(self):
        '''
        获取登录返回的token的url
        '''
        url = self.response['data']['url'][0]
        return url
 
    def get_cookie(self):
        '''
        获取cookie的jar文件
        '''
        url = self.get_response_url( ) +"&callback=jQuery21008240514814031887_1508666806688&_=1508666806689"
        cookie = requests.get(url).cookies
        return cookie
 
    def write_cookie(self):
        cookie = requests.utils.dict_from_cookiejar(self.get_cookie())
        op_json = OperetionJson()
        op_json.write_data(cookie)
 
if __name__ == '__main__':
 
    url = "http://www.jd.com/passport/user/login"
    data = {
        "username" :"18513199586",
        "password" :"111111",
        "verify" :"",
        "referer" :"https://www.jd.com"
    }
    res = json.dumps(requests.post(url ,data).json())
    op_header = OperationHeader(res)
    op_header.write_cookie()

5.4 操作json文件（operation_json.py）

#coding:utf-8
import json
class OperetionJson:
 
    def __init__(self,file_path=None):
        if file_path  == None:
            self.file_path = '../dataconfig/user.json'
        else:
            self.file_path = file_path
        self.data = self.read_data()
 
    #读取json文件
    def read_data(self):
        with open(self.file_path) as fp:
            data = json.load(fp)
            return data
 
    #根据关键字获取数据
    def get_data(self,id):
        print type(self.data)
        return self.data[id]
 
    #写json
    def write_data(self,data):
        with open('../dataconfig/cookie.json','w') as fp:
            fp.write(json.dumps(data))
 
 
 
if __name__ == '__main__':
    opjson = OperetionJson()
    print opjson.get_data('shop')

5.5 操作数据库（connect_db.py）

 #coding:utf-8
import MySQLdb.cursors
import json
class OperationMysql:
    def __init__(self):
        self.conn = MySQLdb.connect(
            host='localhost',
