Well, it's certainly possible to use parallel directory structures -- 
this is one way to do it:

module Xyzzy.Gizmo where

module Test.Gizmo where
import Xyzzy.Gizmo
main = ...

ghc --make -main-is Test.Gizmo.main Test/Gizmo.hs

Or without -main-is,

module Main where
import Test.Gizmo
import Test.Bar
main = testGizmo, testBar ...

ghc --make Tests
