Hi.
We're working on a web application that will integrate (embed) a test from Inquisit Web.
From what we've seen in the video (https://www.millisecond.com/products/inquisit4/weboverview.aspx), a licence must be purchased and used before hand.
We need the ability to test our application with the embedded inquisit web test in advance, and once it's working the way we need it to, then purchase and use the timed license for actual client testing.

How would we go about doing this?
