which tool to use
I have web application developed on asp.NET,I want to automate this application.This web pages contains so many bar and pie charts.Is it possible to automate,if it as many images.Since front end becomes html pages,can i use any web automation tool.Since QTP is for .net also costly.
Re: which tool to use
If its asp.net you should still be able to use any web testing tool.
If you are refering to a .NET web app then, again, you should still be able to use any web test tool to test the front end.You will be looking at the HTML.
If you need to go deeper, or if the app is not just web based then you may need to go for a specific tool to test .NET, like QTP with the .NET addin.
Hope this helps
