In any case you should have configurations in your dub json. For 
the first configuration, the name does not matter, it is used by 
default for command "dub" or "dub build", here you set targetType 
library. The second configuration you name unittest, you set 
targetType executable and you also have to set attribute 
mainSourceFile. This configuration is used automatically by 
command "dub test".
