`dub test` adds its own main file, and removes yours. So essentially, 
it's not building your app.d file at all.

`dub test` is a utility used to test libraries, which typically do not 
have a main function. It's definitely suspect for dub to do this, and 
it's based on historical baggage.

To test an application with dub, use `dub -b unittest`, which builds the 
application the same as always, just with the `-unittest` switch.
