[Haskell-beginners] Where do you put your tests?

AFAIK, it's a good engineering practice to separate the tests from the code
they are supposed to test. Code management issues will be there, but those
can be taken care with the help of cabal like tool.
That way, a person who wants to test will use the test-files and the one
who doesn't want will be spared the trouble of separating tests from the
intended function code.
