Qunar机票搜索场景
访问Qunar机票首页http://flight.qunar.com，选择“单程”，输入出发、到达城市，选择today+7日后的日期，点“搜索”，跳转到机票单程搜索列表页。
在列表页停留1分钟，至到页面上出现“搜索结束”。
如果出现航班列表，对于出现“每段航班均需缴纳税费”的行随机点选“订票”按钮，在展开的列表中会出现“第一程”、 “第二程”；对于没有出现“每段航班均需缴纳税费”的行随机点选“订票”按钮，在展开的列表底部中会出现“报价范围”
如果不出现航班列表，则页面会出现“该航线当前无可售航班”

请使用maven创建java工程，引入Selenium框架，编写WebUI代码，实现上述人工操作和验证。要求能随机验证100个城市对的3个月内的任意搜索条件。
