Testing a storm Bolt

I'm new to apache storm and I was looking for methods to test a bolt without actually building the complete topology. Just wanted to avoid Mock testing. Instead I tried to call the methods of the bolt to emit the output in the OutputCollector object. But I was trying to find a method to get the data from the OutputCollector object and found no method as such. Is there any way I can simply access the values emitted in the OutputCollector object?
