python：当文件中出现特定字符串时执行robot用例

 

 

#coding:utf-8
import os
import datetime
import timedef execute_rpt_db_full_effe_cainiao_city():flag = Truewhile flag:# 判断该文件是否存在# os.path.isfile("/home/ytospid/opt/docker/jsc_spider/jsc_spider/log/call_proc.log")# 存在则获取昨天日期字符串yesterday = datetime.datetime.now()+ datetime.timedelta(-1)yesterday_str = datetime.datetime.strftime(yesterday,'%Y%m%d')# 判断该日志文件中是否包含该字符串，如果存在则表示今日数据已经爬完入库
with open('/home/ytospid/opt/docker/jsc_spider/jsc_spider/log/call_proc.log') as f:for line in f.readlines():if yesterday_str in line:# 再执行30场景检查该表os.system("robot -i rpt_db_full_effe_cainiao_city -l case30_log.html -r case30_report.html -o case30_output.xml /home/ytospid/opt/spider_monitor/菜鸟指数爬虫监控/01_测试用例/接口测试用例/菜鸟指数爬虫结果监控.txt")# print lineprint '已执行30场景'flag = Falsereturn 'OK'print u'休眠5秒'time.sleep(60)execute_rpt_db_full_effe_cainiao_city()if __name__ == '__main__':execute_rpt_db_full_effe_cainiao_city()

例子： 每5秒检查一次test.txt文件，如果出现“hello”，则打开计算器，

import os,timedef execute():with open('test.txt') as f:for line in f.readlines():if 'hello' in line:os.system("calc.exe")returnprint '休息10秒再试试'time.sleep(5)execute()if __name__ == '__main__':execute()
