Using the planner without an imp

Im still waiting for my delivery of imp & extra parts from sparkfun.
ive already made a small android app for my project im about to build,
and i wish to continue working…is it possible?
to start programming and testing my code without actually having the hardware yet?
In a manners of some input received (even http post/get) and then see reactions of hardware such as pin1 = high, pin2=low…and so on

I’m afraid this isn’t possible right now, sorry.
