【开源自动化测试疑难FAQ】【WebDriver】WebDriver对SWFUpload的

? ? ? ?发现个极品开发在上载的时候毫无由头的不去用公司通用的标准控件，居然用一个flash控件，一查发现叫SWFUpload。上google查了好一会，貌似目前WebDriver还是不支持对这玩意的处理的。

? ? ? ?思考了一会，对网页上的组件做自动化无非就是考虑js或者浏览器接口，既然这二者都行不通，那么也许改考虑一下GUI工具，最不济的就是鼠标键盘动作的模拟。所以又查了一会autoit对flash的处理，没有找到对这个页面上这个组件的好的处理方式，因为用暴力的坐标定位的方法可能不具备可移植性。没办法只好用键盘模拟了，试了一下，在flash控件的前一个div单击或者双击之后用一次TAB键，就可以聚焦到flash控件（图中的上载）上，然后再给一个ENTER/RETURN应该可以。反复试了几次，发现TAB可以，而ENTER/RETURN是不行的，幸好我还有点QTP基础，对vbs烂熟，索性调用vbs的键盘模拟试试……结果发现是可以的。
