Improve performance of unit-tests which use parse.com API's

My application is deeply integrated with parse.com and has a lot of unit tests written and much more to go.

And, surprise, I need to generate some test data for each test. The problem is that running all specs could take a lot of time, because app has to communicate with remote parse.com servers.

Is there any library which would store data on local machine instead of sending it to parse? This would make unit testing much more easier.

Thanks
