简单api接口测试框架

最近公司开发了一个app项目，需要进行api接口测试，为了让不会写代码的同事也能参与进来，我写了一个简单的接口测试框架，本身这是第一次写，自己的代码经验也不多，想和大家分享下，评论下不足。
首先这个简易框架有四部分组成：framework公共函数、case测试用例、data数据驱动、report测试报告。整个框架的流程是这样的，用一个循环执行一个api的所有测试用例，测试数据源从excel中读取，执行其中一个case的时候，会调用一个公共的流程，最后将执行结果写入文档。这边重点介绍下公共流程，首先是发送请求，然后对服务器的反馈进行判断，如果是一个有效操作，例如code=0,预期msg和实际一致，那么进行数据库插入数据比对，如果都正确，那么结果正确（当然这边有缺陷，如果是不需要查询数据库的，这个流程就不能用了，需要改进），如果是一个非法操作，那么只判断code和msg，具体代码如下：

#!/usr/bin/env python
#-*- coding:utf-8 -*-
import hashlib
import requests
import MySQLdb
from openpyxl import load_workbook
import sys
import time
class FrameWork(object):
def __init__(self):
self.CaseSuccessful = 'TRUE'
self.CaseFalse = 'FALSE'
self.reportPath = '***'
#字符串md5
def toMd5(self,s):
return hashlib.md5(s).hexdigest()
#高亮
def highlight(self,s):
return "%s[30;2m%s%s[1m"%(chr(27), s, chr(27))
#红色字体
def inRed(self,s):
return self.highlight('') + "%s[31;2m%s%s[0m"%(chr(27), s, chr(27))
#绿色字体
def inGreen(self,s):
return self.highlight('') + "%s[32;2m%s%s[0m"%(chr(27), s, chr(27))
#写入测试结果
def report(self,fileName,caseTitle,describe,resultFlag):
with open(self.reportPath+fileName,'a+') as fp:
if resultFlag == 0:
fp.write(caseTitle+':\t'+self.inGreen(self.CaseSuccessful)+'\t'+describe+'\n')
else:
fp.write(caseTitle+':\t'+self.inRed(self.CaseFalse)+'\t'+describe+'\n')
#get请求
