开发的伴侣就是单元测试,没有测试用例的开发,或者说是没有自动测试的开发是噩梦般的。
在sae python微信公众项目的开发过程中,建立单元测试框架可以大大提高开发效性、项目的稳定性。
下面提供我自己使用的简单sae python测试框架(weixin_unitest.py):
# -*- coding: utf-8 -*- #/usr/bin/env python import sys, urllib, httplib, time, hashlib, random # 配置 interface_url = '***.sinaapp.com:80' # 注意不能加http:// interface_path = '/your path' Token = 'your token' messages = { # 用户关注消息 'subscribe' : '''<xml><ToUserName><![CDATA[your name]]></ToUserName> <FromUserName><![CDATA[tester name]]></FromUserName> <CreateTime>123456789</CreateTime> <MsgType><![CDATA[event]]></MsgType> <Event><![CDATA[subscribe]]></Event> <EventKey><![CDATA[EVENTKEY]]></EventKey> </xml>''', # 用户发送文本信息 'text': '''<xml><ToUserName><![CDATA[your name]]></ToUserName> <FromUserName><![CDATA[test name]]></FromUserName> <CreateTime>1348831860</CreateTime> <MsgType><![CDATA[text]]></MsgType> <Content><![CDATA[test text]]></Content> <MsgId>1234567890123456</MsgId> </xml>''' } def make_post(action): '''模拟用户行为产生的消息提交给接口程序''' conn = httplib.HTTPConnection(interface_url) headers = { "Content-type": "text/xml", "Content-Length": "%d" % len(messages[action])} # 生成签名相关变量 timestamp = int(time.time()) nonce = random.randint(1,100000) signature = makeSignature(Token, timestamp, nonce) params = urllib.urlencode({'signature': signature, 'timestamp': timestamp, 'nonce': nonce}) conn.request("POST", interface_path + "?" +params, "", headers) print messages[action] conn.send(messages[action]) response = conn.getresponse() print response.status, response.reason print response.read() conn.close() def makeSignature(Token, timestamp, nonce): '''生成签名''' try: Token = int(Token) except Exception, e: pass sorted_arr = map(str, sorted([Token, timestamp, nonce])) sha1obj = hashlib.sha1() sha1obj.update(''.join(sorted_arr)) hash = sha1obj.hexdigest() return hash def listAction(): print("======Supported actions:======") for i in messages.keys(): print(i) print("==============================") if __name__ == '__main__': if len(sys.argv) < 2: print (u"Please input your action") listAction() else: if (messages.has_key(sys.argv[1])): make_post(sys.argv[1]) else: print("No this action") listAction()
运行:
python weixin_unitest.py subscribe python weixin_unitest.py text
结合SAEPython(sae服务器),在本地完成开发测试就很方便了。
