The recommended approach, and the one a lot of us use for testing, is setting up a "local dedicated server". If your run arma3server.exe with the exact same mod line as your game but including @aliveserver as well, you can then join this from your normal game client.
Then you can add the details to War Room using your servername and IP address and benefit from all the persistence, maps, AAR and showing off your shiny stats on the profile, and make use of the automated performance data. Just be sure to check your IP address is the same each time you run it up (if you don't have a static IP from your ISP).
BI Community Wiki has lots of details about how to set up dedi servers with server.cfg etc.
