using plesk without a domain

[michaeld9999]

hi
Plesk 9.3 is being provided to us by a hosting company who have provided us with a virtual sql server database.
Currently the website uses a shared sql server database from a different service provider.
I am trying to understand plesk and get everything set up and working before moving the domain and data to the new hosting.
I am told that there is a way within Plesk to use a temporary domain so I can set up the sql server database and the email facility and test it all.
Would someone let me know how this works please.
