i guess he wants just to test his map after compilin a bsp
then u should have your bsp file (eg. yourmap.bsp) in base\maps\ folder,
for your comfort u can keep your .map files there too... then when u compile ur .bsp file i should appear there, if not - put it there
then just simply run tremulous, bring on console (~) and type /sv_pure 0, ENTER, /devmap yourmap (no need to type yourmap.bsp)... and u should see ur map on the screen... if not - report your errors - maybe problem lies in your map (like sv_brushmodel NULL error, or couldnt find spawn point etc.)
report HOW it is not working... what trem says
and i really recommend u runnin your map for test via console, not Play -> Create Server - etc
