Clear db with mongoid3

I like to perform a set up before each time I run a unit test and clear my mongo db, how do I do it with mongoid?

I found some links about it while googling but nothing seemed to work.

If you're using Rails, you can run rake db:mongoid:purge to drop all collections except the system collections.

Or, run rake db:mongoid:drop to drop the database from the current Rails.env.

You might want to take a look at database_cleaner gem which abstracts cleaning databases in specs

This discussion(Delete All Collections in Mongoid 3) in mongoid group seems relevant. There are two methods purge! and truncate!. Purge drops the collections, which means also the indexes. Truncate only drops the documents in each collection, which means you retain indexes, but it is slower than purge.
