What is the best tool for functional testing of a complex web application?

I can confirm that iMacros (that you mentioned) works very well with all kinds of tree views and file uploads. It even supports Flash-based or "ajaxy" file uploads: http://blog.alertfox.com/2011/03/are-file-upload-scripts-on-your-website.html.

Admittedly I am biased, but may I suggest Telerik Test Studio which you can find here: . I just verified we can record and playback clicks on the special expander of a jsTree without any difficulty whatsoever. We also have built-in support for handling file uploads.

What else do you need?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
