Hi,
When facing an application with complex logic performed on the client, I
find that the most convenient way to test is to play by the rules when
submitting the input in the browser, allowing it to perform whatever checks
it wishes.
Simply intercept the request with a proxy and manipulate the fields in the
raw HTTP request. This is sometimes the only way to be able to intelligently
test the application as the JS code might add parameters or perform some
other critical functions that you might remove by accident when editing the
HTML.
Good luck,
Eyal Udassin.

Subject: Testing a web app with heavy JS use
Anybody know of a good way to strip or catch and manipulate input to a web
app that uses JS to do error checking AND specify the input target address?
...oh and the "submit button" is JS driven too...
Other than hand editing 30 screens of JS code?
