Coverage decreased (-2.8%) to 53.913% when pulling bd6524d on gustavojnt:master into 21ed26d on mikemclin:master.

Is there a reason while you chose the method drop? I didn't know if this was common nomenclature for removing a persisted state (like session/cache) in a different package, etc. To me, it seems more like a flush?

The method name can be flush. Thanks for the remark!

Thanks for the contribution. I'll tag it in this evening.
