A recovery test is a test to see if the information given by the owener of the account,to see if incase the account gets hacked you can recover without having to contact the owner.
But be warned the owner can give you just enough information to pass the test but that doesn't mean that the account is completly yours.
The owner could always withold enough information to hack the account back with no problem also the owner has the original ip.
Also incase of the account being locked if the owner provides enough information the account could be his again and if you try to recovery it with the information given to you orginaly you will fail everytime.
Hope this cleared things up.
