简单实现接口自动化测试(基于python+unittest) - 51Testing软件测试论坛

Method：POST
URL：api/match/image/getjson
Request：
{"category": "image","offset": "0","limit": "30","sourceId": "0","metaTitle": "","metaId": "0","classify": "unclassify","startTime": "","endTime": "","createStart": "","createEnd": "","sourceType": "","isTracking": "true","metaGroup": "","companyId": "0","lastDays": "1","author": ""}Response示例：
{"timestamp" : xxx,"errorMsg" : "","data" : {"config" : xxx}Postman测试方法见截图：

测试思路1.获取Postman原始脚本
2.使用requests库模拟发送HTTP请求**
3.对原始脚本进行基础改造**
4.使用python标准库里unittest写测试case**
原始脚本实现
未优化
该代码只是简单的一次调用，而且返回的结果太多，很多返回信息暂时没用，示例代码如下
import requests
url = "http://cpright.xinhua-news.cn/api/match/image/getjson"
querystring = {"category":"image","offset":"0","limit":"30","sourceId":"0","metaTitle":"","metaId":"0","classify":"unclassify","startTime":"","endTime":"","createStart":"","createEnd":"","sourceType":"","isTracking":"true","metaGroup":"","companyId":"0","lastDays":"1","author":""}
headers = { 'cache-control': "no-cache", 'postman-token': "e97a99b0-424b-b2a5-7602-22cd50223c15" }
response = requests.request("POST", url, headers=headers, params=querystring)
print(response.text)优化第一版
调整代码结构，输出结果Json出来，获取需要验证的response.status_code，以及获取结果校验需要用到的results['total']

#获取http请求的status_codeprint "Http code:",response.status_code
#获取结果中的total的值print results['total']#print(response.text)优化第二版
接口调用异常处理，增加try，except处理，对于返回response.status_code，返回200进行结果比对，不是200数据异常信息。
