Yes, the trial is fully-featured, though obviously, you will get a watermark on every output you produce, but that should be fine for testing purpose.

Regarding the dev license, I'm not aware of any difference in terms of features between a dev and prod license, unless your dev license is a different "level", in other words, a Watch or Office license instead of a Production license. That could affect the available features. You'd have to call Activations and check with them exactly what kind of license you have, and what restrictions it has.

But for the trial, it should be full-featured, with a watermark on the outputs you produce using it.
