DbFit - How to query 2 databases from different servers?

Question

We can setup test and query one database on the server (or multiple dbs on the same server) using the foll.:

    !|dbfit.SQLServerTest|

!|Connect|RSSPL25|sa|sa|DatabaseB|

!|Query| select 'test' as x|

Within the same test, how do we query another database from a different server?

Any simple example will help me.
