unittest blocks are skipped completely by the compiler when the 
-unittest command line option is not passed. So you can leave 
unittest code embedded in between the rest (specially for proper 
unit tests of functions and classes) and there is no need to 
worry about file separation. Even when you write a separate file 
with tests, all its code inside unittest blocks can be skipped 
for the compiler.

In the case of dub, it has a dedicated option, "dub test" instead 
of "dub build" or "dub run"
