Is eValid unique? I mean, there seem to be a lot of test tools that are somehowrelated to a browser, but eValid seems to be the only one that really IS a browser? Why is that?

Yes, eValid is unique and certain aspects of how eValid is put together have qualified it for two US Patents, so far. Other patents are "applied for".

And, yes, there do appear to be a lot of test tools around that look like they are build into a browser, but most of them accomplish test playback through use of the JavaScript engine. This is an attrative method to use because it easy, the APIs are well known, and most of the time it works well. But not when you have an AJAX application, which also uses the JavaScript engine. In that case a resource contention arises that causes the test playback process to interfere with the web application that is being tested -- with unpleasant un-realistic behavior the result.

Instead, eValid takes the direct approach by effectively incorporating the entire IE browser engine inside the eValid executable, thereby providing direct access to the internal DOM. This way, when eValid runs an AJAX applications, it does NOT interfere with the operation of AJAX. The result is that timing and bytecount (capacity) measurements are completely realistic.
