Selenium Grid
Okay next is selenium grid. So I thing we are running short of time so I will take some of the questions on the last five minutes okay. The challenge with the online app is that on the user side there could be any kind of combination of various variables. You know text boxes check, so one is that there are various kinds of variables on the web page and then there are other the environments themselves on the user side are different.
So somebody is using windows 7, somebody is using windows 8, somebody is using Redhat, somebody is using ubuntu, somebody is using Mac then there are these versions of these then there are these service packs over there. So let us say on OS side windows, Mac and Linux are three variants and browsers are IE, Firefox, chrome, Safari etc.
