接口测试 PICT 组合 +PageObject+Python asyncio 接口测试
之前写过组合测试生成参数在接口测试中的探索篇,现在正式运用的项目中
说明
全对偶接口生成参数
功能
- python3.4 多线程，在使用 asyncio aiohttp 时，遇到接口非 200 时，卡着一直
- unittest 参数化
- pageobject
- 数据维护用的 YMAL
- 基于 PICT 全对偶生成接口参
代码分析
aiohttp asyncio 封装
class request():
def __init__(self, **kwargs):
'''
http请求的封装，传入dict

'''
self.req = kwargs
def get(self, url, param):
data = {}
_url = self.req["protocol"] + self.req["host"] + ":" + str(self.req["port"]) + url
print(_url +" get请求参数为:"+str(param))
try:
response = yield from aiohttp.request("GET", _url, headers=self.req["header"], params=param)
string = (yield from response.read()).decode('utf-8')
if response.status == 200:
data = json.loads(string)
else:
print("data fetch failed for")
print(response.content, response.status)
data["status_code"] = response.status
print(data)
except asyncio.TimeoutError:
print("访问失败")
except UnicodeDecodeError:
print("接口崩溃了")
return data
def post(self,url, param):
data = {}

其他
- 后续会加上统计报告
- 后续加上检查点的检查
- 查看开源地址
补充
- 在使用 asyncio aiohttp 时，遇到接口非 200 时，一直卡着，设置了超时也不行，后续再研究下！现在采用的是多线程

有个疑问, 一组要求顺序 POST 的请求, 可以用 asyncio 吗
还没看，先顶一下
楼主你这是针对参数少的，像我们公司接口都是 20 多个参数，难道也这样去排列组合？那接口多的话是不是太耗时间

比如我要发一个购买接口，发这个接口之前需要先发送登录，取 Cookie，这种情况可以用 asyncio 吗。我的理解是，不等待返回直接执行下面的语句，这样的话不适合这类情况把？

恩，我的疑惑是使用 asyncio 会造成请求顺序的更改吗，比如一组接口，登录->购买->支付->退货 ，看起来是顺序执行的，这样的话能使用吗

你想严格控制接口的访问顺序，在用 unittest 的时候你可以这样处理,不知道是不是你想要的：
def login():
pass
def buy():
pass
def pay():
pass
def testShopping():
login()
buy()
pay()
